The highway system of the United States is a network of interconnected state, U.S., and Interstate highways. Each of the fifty states, the District of Columbia, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands own and maintain a part of this vast system, including U.S. and Interstate highways, which are not owned or maintained at the federal level.


Interstate Highways have the highest speed limits and the highest traffic numbers. Interstates are numbered in a grid: even-numbered routes for east–west routes (with the lowest numbers along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). Three-digit Interstates are, generally, either beltways or spurs of their parent Interstates (for example, Interstate 510 is a spur into the city of New Orleans, Louisiana, and is connected to Interstate 10).


U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.


State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.


Scenic byways can be designated over any classification of road in the United States. There are the National Scenic Byways, National Forest Scenic Byways and Bureau of Land Management Back Country Byways at the national level. Most states have their own system for designating byways, some more systematic than others. Native American tribes may designate byways as well.

- Image 1Interstate 496 (I-496) is an auxiliary Interstate Highway that passes through downtown Lansing in the US state of Michigan. Also a component of the State Trunkline Highway System, the freeway connects I-96 to the downtown area. It has been named the R.E. Olds Freeway (sometimes just Olds Freeway) for Ransom E. Olds, the founder of Oldsmobile and the REO Motor Car Company. I-496 runs east–west from I-96/I-69 near the downtown area and north–south along a section that runs concurrently with US Highway 127 (US 127). The trunkline also passes a former assembly plant used by Oldsmobile and runs along or crosses parts of the Grand and Red Cedar rivers.
Construction of I-496 started in 1963, and the freeway opened on December 18, 1970. Segments of the freeway south of downtown Lansing were built in the location of a historically black neighborhood. In the opinion of some, this neighborhood was formed based on the segregationist practices of the early 20th century. Community leaders worked for different housing opportunities for the black residents displaced by I-496 rather than fight the freeway. As the trunkline neared completion, competing proposals to name it resulted in two similar, but separate designations applied to I-496. The city originally approved one name in honor of a former mayor. The local historical society proposed that the state name it as a memorial to Olds after the demolition of the Olds Mansion. The city renamed it the Oldsmobile Expressway, the name under which it opened in December 1970. Two years later, the Michigan Legislature restored its preferred name and it has been the Olds Freeway since.

It begins at NY 52 in Lake Carmel, and intersects Interstate 84 (I-84) shortly thereafter. It crosses NY 164 and NY 292 as it heads into the northeastern part of the county, finally curving east to reach its northern terminus at NY 22 just south of the Dutchess County line. The route passes several historical sites.
Part of modern-day Route 311 was originally the Philipstown Turnpike, a road built in 1815 to overcome a lack of transportation when the Hudson River froze during the winter months. The turnpike was a large business center for the county, though it was abandoned due to insufficient tolls to maintain it. Another section was constructed in the early 1900s, from the Patterson Baptist Church near the modern-day intersection of Route 311 and Route 164 to the Village of Patterson, by a group of Italian immigrants.

US 41) was a state trunkline highway that served as a business loop off US 41 and M-28 in Marquette, Michigan, along Washington and Front streets. The streets serve the downtown area of Marquette and are bordered by several commercial properties and businesses. Those two streets originate with the early founding of the city in the middle of the 19th century. Jurisdiction over them was transferred to the city as part of a highway swap that resulted in the decommissioning of the trunkline in 2005. It was also previously co-designated Bus. M-28, mirroring the Bus. US 41/Bus. M-28 designation previously used along Bus. M-28 in Ishpeming and Negaunee. Washington and Front streets had been a part of the state highway system since the 1910s, and a part of the United States Numbered Highway System since 1926. The business loop designation dates back to the 1960s and was removed in 2005. (Full article...)
- Image 4Interstate 696 (I-696) is an east–west auxiliary Interstate Highway in the Metro Detroit region of the US state of Michigan. The state trunkline highway is also known as the Walter P. Reuther Freeway, named for the prominent auto industry union head by the Michigan Legislature in 1971. I-696 is a bypass route, detouring around the city of Detroit through the city's northern suburbs in Oakland and Macomb counties. It starts by branching off I-96 and I-275 at its western terminus in Farmington Hills, and runs through suburbs including Southfield, Royal Oak and Warren before merging into I-94 at St. Clair Shores on the east end. It has eight lanes for most of its length and is approximately 10 miles (16 km) north of downtown Detroit. I-696 connects to other freeways such as I-75 (Chrysler Freeway) and M-10 (Lodge Freeway). Local residents sometimes refer to I-696 as "The Autobahn of Detroit".
Planning for the freeway started in the 1950s. Michigan state officials proposed the designation I-98, but this was not approved. Construction started on the first segment in 1961, and the Lodge Freeway was designated Business Spur Interstate 696 (BS I-696) the following year. The western third of the freeway opened in 1963, and the eastern third was completed in January 1979. The central segment was the subject of much controversy during the 1960s and 1970s. Various municipalities along this stretch argued over the routing of the freeway such that the governor locked several officials into a room overnight until they would agree to a routing. Later, various groups used federal environmental regulations to force changes to the freeway. The Orthodox Jewish community in Oak Park was concerned about pedestrian access across the freeway; I-696 was built with a set of parks on overpasses to accommodate their needs. The Detroit Zoo and the City of Detroit also fought components of the freeway design. These concessions delayed the completion of I-696 until December 15, 1989. Since completion, the speed limit was raised from 55 to 70 miles per hour (89 to 113 km/h). In addition, some interchanges were reconfigured in 2006.

It is the longest primary highway in the state and is maintained by the Iowa Department of Transportation (Iowa DOT). The route in Iowa begins at the Missouri River crossing at Blair, Nebraska, and ends at the Mississippi River crossing at Clinton, Iowa. Along the way, it serves Denison and Carroll in western Iowa, Boone, Ames, and Marshalltown in central Iowa, and Tama, Cedar Rapids, and DeWitt in eastern Iowa. Cutting across the central portion of the state, US 30 runs within close proximity of the Union Pacific Railroad's Overland Route for its entire length.
US 30 was conceived as a part of the Lincoln Highway, the first transcontinental highway in the United States. A route through Iowa was chosen because of the important link between Omaha, Nebraska, and Chicago, Illinois. As the U.S. Highway System came into being in the 1920s, and the Lincoln Highway became US 30, federal money started to pay for paving Iowa's dirt roads. By 1931, the route had been paved across the entire state.

It is a 2.37-mile (3.81 km) extension of the Atlantic City Expressway, connecting it to New Jersey Route 87, which leads into Brigantine via the Marina district of Atlantic City. Locally, the freeway is known as "the Tunnel", due to the tunnel along its route that passes underneath the Westside neighborhood. The freeway is owned and operated by the South Jersey Transportation Authority (SJTA); it has an unsigned state highway designation of Route 446X.
Proposals for a similar connector road in Atlantic City date to 1964; planning began in 1995 after businessman Steve Wynn proposed a new casino hotel in the Marina district. The goals were to reduce traffic on Atlantic City streets and improve access to the Marina district and Brigantine. It was supported by Governor Christine Todd Whitman and Mayor Jim Whelan, but faced major opposition during its planning. Residents whose homes were to be destroyed for the tunnel construction fought the project, and competing casino owner Donald Trump filed lawsuits to prevent its construction.

It begins at Interstate 8 (I-8) in El Cajon and continues to Lakeside as the San Vicente Freeway before becoming an undivided highway through the eastern part of Poway. In the town of Ramona, the route turns into Main Street before ending at SR 78. SR 67 provides direct access from the city of San Diego to the East County region of San Diego County, including Ramona and Julian.
The route has existed as a railroad corridor since the turn of the 20th century. A highway known as the Julian road was built by 1913, and was designated as Legislative Route 198 in the state highway system by 1935. Route 198 was renumbered SR 67 in the 1964 state highway renumbering. A freeway south of Lakeside was built in the late 1960s, and opened to traffic in 1970. Since then, the portion of the highway north of Lakeside has become known for a high number of traffic accidents and related fatalities. The California Department of Transportation (Caltrans) has made several attempts to remedy the problem and make the road safer. (Full article...) - Image 8US Highway 16 (US 16), also called Grand River Avenue for much of its length in the state, was a principal road prior to the post-World War II construction of freeways in the state of Michigan. Before the creation of the United States Numbered Highway System in 1926, the highway had been designated as a state highway numbered M-16. The modern route of Grand River Avenue cuts across the Lower Peninsula in a northwest–southeast fashion from near Grand Rapids to Detroit. Before the late 1950s and early 1960s, US 16 followed other roads between Muskegon and Grand Rapids, and then Grand River Avenue through Lansing to Detroit. In the years immediately preceding the creation of the Interstate Highway System, US 16 was shifted from older roads to newer freeways. Later, it was co-designated as an Interstate Highway. When the gap in the freeway was filled in around Lansing, the US 16 designation was decommissioned in the state. The freeway was solely designated Interstate 96 (I-96) east of Grand Rapids and I-196 west of that city.
The original pathway along the Grand River Avenue corridor was an Indian trail, a footpath used by the native population. The first European settlers to the area also used this trail and in some areas enlarged it for the passage of wagons. In Detroit, Grand River is one of five major avenues (along with Woodward, Michigan, Gratiot, and Jefferson) planned by Judge Augustus Woodward in 1805 that extended from Downtown Detroit in differing radial directions; Grand River Avenue extends northwesterly from the city's downtown. In the middle of the 19th century, the trail was expanded into a plank road that formed the basis for one of the first state trunkline highways as M-16 in the early 20th century. Later, the highway was rerouted to replace M-126 and create M-104. Current segments of the roadway are still part of the state highway system as sections of M-5, M-11, M-43 or business loops off I-96. The portion of Grand River Avenue in Detroit between I-96 and the intersection with Cass Avenue and Middle Street in Downtown Detroit was formerly an unsigned state trunkline, sometimes referred to as Old Business Spur I-96 (Old BS I-96) until 2016 when it was designated as an extension of M-5.

The north–south freeway serves as a bypass route of I-5 along the east side of Portland, Oregon, and Vancouver, Washington. It intersects several major highways and serves Portland International Airport.
The freeway is 37 miles (60 km) long and connects to I-5 at both of its termini: to the south in Tualatin, Oregon, and to the north in Salmon Creek, Washington. I-205 is named the Veterans Memorial Highway and East Portland Freeway No. 64 in Oregon (see Oregon highways and routes). From Oregon City to Vancouver, the corridor is paralleled by a multi-use bicycle and pedestrian trail, as well as portions of the MAX Light Rail system between Clackamas and northeastern Portland.

In Michigan, it is a state trunkline highway that enters the state south of New Buffalo and runs eastward through several metropolitan areas in the southern section of the state. The highway serves Benton Harbor–St. Joseph near Lake Michigan before turning inland toward Kalamazoo and Battle Creek on the west side of the peninsula. Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossing I-69 in the process. I-94 then runs through Jackson, Ann Arbor, and portions of Metro Detroit, connecting Michigan's largest city to its main airport. Past the east side of Detroit, the Interstate angles northeasterly through farmlands in The Thumb to Port Huron, where the designation terminates on the Blue Water Bridge at the Canada–United States border.
The first segment of what later became I-94 within the state, the Willow Run Expressway, was built near Ypsilanti and Belleville in 1941, with an easterly extension to Detroit in 1945. This expressway was initially numbered M-112. In the mid-1950s, state and federal officials planned an Interstate to replace the original route of US Highway 12 (US 12). By 1960, the length of I-94 was completed from Detroit to New Buffalo. Two years later, the US 12 designation was dropped from the freeway. Subsequent extensions in the 1960s completed most of the rest of the route, including the remaining sections between Detroit and Port Huron which superseded the routing of US 25. The last segment opened to the public in 1972 when Indiana completed its connection across the state line. Since completion, I-94 has remained relatively unchanged; a few interchanges have been rebuilt, a second span was constructed for the Blue Water Bridge, and, in 1987, a plane crashed on the freeway during takeoff from the airport in Detroit. The routing of I-94 is notable for containing the first full freeway-to-freeway interchange in the United States, connecting to the Lodge Freeway (M-10), and for comprising the first complete border-to-border toll-free freeway in a state in the United States. The highway has one auxiliary route, I-194, which serves downtown Battle Creek, and eight business routes. Various segments have been dedicated to multiple people and places. (Full article...) - Image 11State Route 75 (SR 75) is a 13-mile (21 km) north-south state highway in San Diego County in the U.S. state of California. It is a loop route of Interstate 5 (I-5) that begins near Imperial Beach, heading west on Palm Avenue. The route continues north along the Silver Strand, a thin strip of land between the Pacific Ocean and San Diego Bay, through Silver Strand State Beach. SR 75 then passes through the city of Coronado as Orange Avenue and continues onto the San Diego–Coronado Bay Bridge, which traverses the bay, before joining back with I-5 near downtown San Diego.
The Silver Strand Highway was constructed and open to the public by 1924. What would become SR 75 was added to the state highway system in 1933, and designated Legislative Route 199 in 1935. SR 75 was not officially designated until the 1964 state highway renumbering. The Coronado Bay Bridge opened in 1969, and provided a direct connection between San Diego and Coronado. Since then, various proposals have taken place to relieve commuter traffic between San Diego and Naval Air Station North Island that traverses the city of Coronado. However, none of these proposals have gained support, including an attempt in 2010.

It was created in 2003 as a renumbering of U.S. Route 666 (US 666). With the US 666 designation, the road was nicknamed the "Devil's Highway" because of the significance of the number 666 to many Christian denominations as the Number of the Beast. This Satanic connotation, combined with a high fatality rate along the New Mexico portion, convinced some people the highway was cursed. The problem was compounded by persistent sign theft. These factors led to two efforts to renumber the highway, first by officials in Arizona, then by those in New Mexico. There have been safety improvement projects since the renumbering, and fatality rates have subsequently decreased.
The highway, now a spur route of US 91 via its connection to US 191, runs through New Mexico, Colorado and Utah, as well as the tribal nations of the Navajo Nation and Ute Mountain Ute Tribe. The highway passes by two mountains considered sacred by Native Americans: Ute Mountain and an extinct volcanic core named Shiprock. Other features along the route include Mesa Verde National Park and Dove Creek, Colorado, the self-proclaimed pinto-bean capital of the world. (Full article...) - Image 13U.S. Highway 8 (US 8) is a United States Numbered Highway that runs primarily east–west for 280 miles (451 km), mostly within the state of Wisconsin. It connects Interstate 35 (I-35) in Forest Lake, Minnesota, to US 2 at Norway, Michigan. Except for the short freeway segment near Forest Lake, a section near the St. Croix River bridge, the interchange with US 51, and a three-mile (4.8 km) stretch west of Rhinelander, Wisconsin, it is mostly an undivided surface road. As a state highway in the three states, US 8 is maintained by the Minnesota, Wisconsin and Michigan departments of transportation (MnDOT, WisDOT, and MDOT, respectively).
The highway was originally commissioned on November 11, 1926, with the rest of the original U.S. Highway System. At the time, it ran between Forest Lake, Minnesota, and Pembine, Wisconsin, with a planned continuation to Powers, Michigan. Several changes have been made to the routing of the highway since then. The western end was extended south to Minneapolis before it was truncated back to Forest Lake. Other changes on the east end have moved that terminus from the originally planned end location at Powers to the current location in Norway. Internal WisDOT and MDOT map files at various times have shown plans to reroute the highway to connect to the original planned 1926 terminus. US 8's course through the three states has also been shifted to follow different alignments over the years. (Full article...) - Image 14M-6, or the Paul B. Henry Freeway, is a 19.7-mile-long (31.7 km) east–west freeway and state trunkline highway in the United States that serves portions of southern Kent and eastern Ottawa counties south of Grand Rapids, Michigan. Although the freeway is named for Paul B. Henry, local residents and the press continue to use the original name, South Beltline as well on occasion. The freeway connects Interstate 196 (I-196) on the west with I-96 on the east. M-6 also provides a connection to U.S. Highway 131 (US 131) in the middle of its corridor while running through several townships on the south side of the Grand Rapids metropolitan area in Western Michigan. Each end is in a rural area while the central section has suburban development along the trunkline.
The freeway was originally conceived in the 1960s. It took 32 years to approve, plan, finance, and build the freeway from the time that the state first authorized funding in 1972 to the time of the ribbon-cutting ceremony in 2004 that opened the South Beltline to traffic. The project cost around $700 million or around $35 million per mile (approximately $22 million per kilometer). Initial construction started in November 1997, with the first phase opened in November 2001. The full freeway was opened in November 2004. The first phase of construction was completed in asphalt, while the second and third phases were built in concrete. The project was built with two firsts: the first single-point urban interchange (SPUI; /ˈspuːiː/) in Michigan, and a new technique to apply the pavement markings, embedding them into the concrete to reduce the chance of a snowplow scraping them off. In advance of the opening of the freeway to traffic, the Michigan Department of Transportation (MDOT) allowed the public to walk or bike the South Beltline in an open-house event called the "Southbelt Shuffle". (Full article...) - Image 15Maryland Route 36 (also known as MD 36 or Route 36) is a 29.43-mile (47.36 km) state highway located in Allegany County, Maryland, United States. MD 36's southern terminus is at the West Virginia Route 46 (WV 46) bridge in Westernport and its northern terminus is at U.S. Route 40 Alternate (US 40 Alt.) near Cumberland. Between Westernport and Frostburg, it is known as Georges Creek Road, and from Frostburg to Cumberland it is known as Mount Savage Road. Like the majority of Maryland state highways, MD 36 is maintained by the Maryland State Highway Administration (MDSHA).
MD 36 serves as the main road through the Georges Creek Valley, a region which is historically known for coal mining, and has been designated by MDSHA as part of the Coal Heritage Scenic Byway. MD 36 is the main road connecting the towns of Westernport, Lonaconing, and Midland in southwestern Allegany County, as well as Frostburg, Mount Savage, and Corriganville in northwestern Allegany County.

- Image 1Mississippi Highway 365 (MS 365) is a state highway in northeastern Mississippi. The route starts at MS 30 in Burton and travels northward. It travels into Burnsville and intersects U.S. Route 72 (US 72). MS 365 continues northeastward and ends at MS 25 west of Pickwick Lake. The route was designated by 1950, connecting from MS 30 to MS 364. It was extended northward to MS 356 around 1958 and was completely paved by 1964. The route replaced parts of MS 356 in 1965, and its northern terminus was changed to MS 25. (Full article...)
- Image 2U.S. Route 206 (US 206) is a 130.23-mile-long (209.58 km) north–south United States Numbered Highway primarily in the state of New Jersey. Its southern terminus is at an intersection with US 30 and Route 54 in Hammonton, while its northern terminus is at an intersection with US 209 near Milford, Pennsylvania. For much of its length, US 206 is a rural two-lane undivided road that passes through the Pine Barrens, agricultural areas, and the Appalachian Mountains of northwestern New Jersey, with some urban and suburban areas. The route connects several cities and towns, including Bordentown, Trenton, Princeton, Somerville, Roxbury, Netcong, and Newton. The road is known as the Disabled American Veterans Highway for much of its length.
What is now US 206 in New Jersey was designated as part of several state routes prior to 1927, including pre-1927 Route 2 between Bordentown and Trenton in 1916, pre-1927 Route 13 between Trenton and Princeton in 1917, and pre-1927 Route 16 between Princeton and Bedminster Township in 1921. The current routing along pre-1927 Route 2 became a part of US 130 in 1926. In 1927, current US 206 became Route 39 between Hammonton and White Horse, Route 37 between White Horse and Trenton, Route 27 between Trenton and Princeton, Route 31 between Princeton and Newton, and Route S31 between Newton and the Delaware River. In the later 1930s, US 206 was designated to connect US 30 in Hammonton north to US 6 and US 209 in Milford; the northern terminus was moved to its current location in the 1940s. The state highways running concurrently with US 206 in New Jersey were removed in 1953. In the 1960s, two separate freeways were proposed for US 206 but never built. The first freeway was to connect Hammonton south along the Route 54 corridor toward Route 55 and the planned Route 60 in Vineland and Millville. The other US 206 freeway was planned in northwestern New Jersey, connecting Interstate 80 (I-80) in Netcong north to Montague Township. Construction began for a bypass of US 206 around Hillsborough Township in 2010 and was completed in 2021. The New Jersey Department of Transportation (NJDOT) widened the route in Byram Township to alleviate congestion, with completion in 2013.

Officially, NY 324 begins at NY 384 in Niagara Falls and overlaps Interstate 190 (I-190, the Niagara Section of the New York State Thruway) south to Grand Island, where it separates from I-190 and continues southward as Grand Island Boulevard. As signed, however, NY 324 begins at the southern end of the official overlap and is contained entirely within Erie County. At the southern edge of Grand Island, NY 324 joins I-190 to cross over to the mainland, where it runs due east across three towns before reaching its eastern end at a junction with NY 5 in the town of Clarence.
NY 324 is known by two names along its routing: Grand Island Boulevard on Grand Island and Sheridan Drive in the northern suburbs of Buffalo. As the latter, the route serves as a major commercial strip for Tonawanda, Amherst, and Clarence. NY 324, assigned c. 1933, is one of two routes to occupy part of Sheridan Drive; the other is New York State Route 325, which follows the westernmost 1.42 miles (2.29 km) of the street. NY 324 once extended northwest to downtown Niagara Falls; however, it was truncated to its current western terminus on January 1, 1962. (Full article...) - Image 4New York State Route 215 (NY 215) was a north–south state highway located within the town of Hamlin in Monroe County, New York, in the United States. It served as the primary highway to and from Hamlin Beach State Park prior to the construction of the Lake Ontario State Parkway. The southern terminus of the route was at an intersection with NY 360 east of the hamlet of Morton. Its northern terminus was at the park on the shore of Lake Ontario. The entirety of NY 215 was named Redman Road.
NY 215 was assigned in the early 1940s to provide a signed connection between NY 360 and Hamlin Beach State Park. It ceased to exist in the early 1970s once it was severed from the Lake Ontario shoreline by a westward extension of the Lake Ontario State Parkway. However, the remaining portion of NY 215 remained state maintained for another 30 years as New York State Route 941P, an unsigned reference route. Ownership and maintenance of NY 941P was transferred to Monroe County as part of a highway maintenance swap that took effect on November 26, 2007. The former routing of NY 941P is now part of unsigned County Route 236 (CR 236).

In Delaware, the route runs a southwest–northeast path through Sussex County. Even though US 9 is signed north–south for the remainder of its route, the segment in Delaware is signed east–west. The highway runs from its western terminus at US 13 in Laurel northeast to the Cape May–Lewes Ferry terminal in Lewes, where the ferry carries the route across the Delaware Bay to North Cape May, New Jersey. US 9 passes through rural areas and serves the communities of Laurel, Georgetown, and Lewes. US 9 intersects Delaware Route 20 (DE 20) in Hardscrabble, US 113 and DE 18/DE 404 in Georgetown, DE 30 in Gravel Hill, DE 5 in Harbeson, and DE 1 at the Five Points intersection in Nassau. US 9 runs concurrent with DE 404 between Georgetown and Five Points and with DE 1 between Five Points and Carpenters Corner.
What is now US 9 in Delaware was originally built as a state highway during the 1920s and designated by 1936 as Delaware Route 28 (DE 28) between Laurel and Georgetown and a part of DE 18 between Georgetown and Lewes. US 9 was extended to Delaware from New Jersey by way of the Cape May–Lewes Ferry in 1974, replacing all of DE 28 and the portion of DE 18 between Georgetown and Five Points, with the route aligned to bypass Lewes. DE 404 was designated concurrent with the portion of US 9 between Georgetown and Five Points by 1987.

The highway connects SH 87 to Coast Guard Station Galveston, on the eastern portion of Galveston Island. At just under 0.9 miles (1.4 km) in length, SH 168 is the second-shortest Texas state highway. The road travels along the edge of residential area for most of its length before it bends northeast and runs through a small marsh.
The route was first proposed by 1932; it would have traveled through Atascosa and Wilson counties. Portions of the proposal were replaced by SH 97 by at least 1935, while the rest was cancelled. State Highway 87 first followed the routing of SH 168, but was moved by 1961. A short railroad spur was built along the course of the route, and SH 168 was officially designated on October 24, 1985.

It was opened as a toll road in 1971 and classified as a state road two years later. The tolls were removed in 1990. It was named after Pineda, a former village east of Suntree on U.S. Route 1 (US 1). With interchanges at US 1 (SR 5), South Tropical Trail (County Road 3, CR 3), and South Patrick Drive (SR 513), the Pineda Causeway is (along with SR A1A) the primary access for Patrick Space Force Base and the southern end of Merritt Island. From US 1 to the eastern terminus, it is part of the Indian River Lagoon Scenic Highway system. (Full article...)
- Image 8Interstate 295 (I-295) in Delaware, New Jersey, and Pennsylvania is an American auxiliary Interstate Highway. It is designated as a bypass around Philadelphia, and a partial beltway of Trenton.
The route begins at the interchange with I-95 south of Wilmington, and runs to an interchange with I-95 in Bristol Township, Pennsylvania. The highway heads east from I-95 and crosses the Delaware River into New Jersey on the Delaware Memorial Bridge, running concurrently with US 40. Upon entering New Jersey, I-295 runs concurrently with the New Jersey Turnpike and US 40 for a brief 0.5 miles (0.80 km) until splitting away at exit 1 and runs parallel to the turnpike for most of its course in the state. After a concurrency with US 130 in Gloucester County, I-295 has an interchange with I-76 and Route 42 in Camden County. The freeway continues northeasterly towards Trenton, where it interchanges with I-195 and Route 29 before bypassing the city to the east, north, and west, crossing the Delaware River on the Scudder Falls Bridge into Pennsylvania. In Pennsylvania, I-295 is signed as an east–west road and heads south to its other terminus at I-95. I-295 is one of two auxiliary Interstates in the US to enter three states, the other being the I-275 beltway around Cincinnati, which enters Ohio, Indiana, and Kentucky.

It links Rochester to its eastern suburbs and to western Wayne County. The western terminus of the route is at exit 7 on NY 590 just inside the Rochester city limits. Its eastern terminus is at NY 350 in Walworth. NY 286 is named Browncroft Boulevard from NY 590 to its junction with Qualtrough and Clark roads in Penfield. This portion of the highway passes through predominantly residential areas. East of this intersection, the route is known as Atlantic Avenue and traverses more rural areas.
The entirety of NY 286 east of Blossom Road was originally designated as part of NY 35 during the 1930 renumbering of state highways in New York. NY 35 exited Rochester on Blossom Road and followed it east to modern NY 286. The remainder of Browncroft Boulevard was designated as New York State Route 35B, an alternate route of NY 35, in the mid-1930s. The NY 35 and NY 35B designations were eliminated in the early 1940s and replaced with NY 383 and New York State Route 383B, respectively. NY 383 was truncated to downtown Rochester in 1949, at which time its former routing from Rochester to Walworth became NY 286. NY 383B was renumbered accordingly to New York State Route 286A.

State Route 546 (SR 546) is a state highway in Whatcom County, Washington, United States. It runs east–west for 8 miles (13 km) near the Canadian border, connecting SR 539 near Lynden to SR 9 near Nooksack and Sumas. The highway is a major freight corridor and serves as an alternate route between Bellingham and the Sumas border crossing.
The highway runs along Badger Road, which was built in the 1890s and paved by the county government in 1922 per the request of citizen petitions. It was incorporated into the state highway system from 1937 to 1951 as part of Secondary State Highway 1A (SSH 1A), which connected to Blaine and Sedro-Woolley. The Lynden section was replaced with a southerly route and re-designated as a branch of SSH 1B in 1957. During the 1964 state highway renumbering, SR 546 replaced the SSH 1B branch, while the rest of the highway became SR 539. Between 2013 and 2016, the state government built a set of three roundabouts on SR 546 in northern Lynden to replace intersections that had been the site of major collisions.

Proposals have been heard from since the 1960s, including highways connecting from I-5 all the way to the Canada–US border, and some just between I-5 and I-90. The Washington State Department of Transportation (WSDOT) has no projects designated I-605 at this time. However, some I-605 proposals have included State Route 18, which has been partially constructed as a freeway. (Full article...)
- Image 12Arden Valley Road is an east-west parkway located in Southfields, New York, in the United States, that travels through Harriman State Park and is owned by the Palisades Interstate Park Commission. At 5.2 miles (8.4 km) long, it begins at New York State Route 17 (NY 17) in Southfields and ends at Seven Lakes Drive in Harriman State Park. Arden Valley Road also serves a trout stocking area for the Ramapo River. The road is located entirely in Orange County and is home to the Elk's Pen Trailhead in Harriman State Park. In 1921, plans arose by the commission to construct the road, which was completed the same year and stretched along the borderline with the Harriman estate. Major William A. Welch ordered 75 elk from Yellowstone National Park to be placed in a wired cage between Arden and Southfields in 1919. The elk eventually disappeared from the pen by 1942, and the area became the current Elk's Pen trailhead for trails within Harriman State Park. (Full article...)
- Image 13Interstate 95 (I-95) is an Interstate Highway on the east coast of the United States, connecting Florida with Maine. Within the state of New Hampshire, it serves the Seacoast Region and is a toll road named the Blue Star Turnpike or New Hampshire Turnpike. The sixteen-mile (26 km) turnpike is maintained by the New Hampshire Department of Transportation (NHDOT) Bureau of Turnpikes and has a single toll plaza near Hampton.
The Blue Star Turnpike begins near the Massachusetts state line in the town of Seabrook and travels north through Hampton and its neighboring municipalities. It then continues around Portsmouth and crosses the Piscataqua River Bridge at the Maine state line, where it becomes the Maine Turnpike. New Hampshire's portion of I-95 is the shortest of any state that the Interstate passes through; the highway is the main thoroughfare between urban areas in Massachusetts and points in Maine.

It travels a distance of 34.62 miles (55.72 km) and is one of the few roads that provides direct access from McHenry County to Interstate 94 (Tri-State Tollway) in Lake County. Throughout its length, it shifts between two and four lanes as it passes through a setting that consists of open rural areas, as well as larger developments and heavy congestion.
Although small capacity expansions have been made over time, a lengthy two lane section of road in the Grayslake vicinity has yet to see any major expansion. This key segment has been the subject of much debate regarding the greater traffic flow across north-central Lake County. In October 2009, a special council approved a unified vision for a plan for most of the Lake County portion of Illinois 120, which includes a long discussed bypass around downtown Grayslake.

Also known as the Veterans Memorial Highway, it runs 40.54 miles (65.24 km) from an intersection with Route 47 in Port Elizabeth north to an interchange with Route 42 in Gloucester County. The Route 55 freeway serves as a main road through Cumberland and Gloucester counties, serving Millville, Vineland, and Glassboro. It is used as a commuter route north to Philadelphia and, along with Route 47, as a route from the Delaware Valley to the Jersey Shore resorts in Cape May County. Route 55 has a posted speed limit of 65 miles per hour (105 km/h) for most of its length.
What is now Route 55 was originally proposed in the 1950s as a toll road called the Cape May Expressway that was to run from the Walt Whitman Bridge to Cape May. In 1962, the New Jersey Expressway Authority was created to build the Cape May Expressway and the Atlantic City Expressway. However, by 1965, the road to Cape May was turned over to the New Jersey Department of Transportation (NJDOT) and designated as Route 55, which was to run from Westville to Cape May Court House. The first portion of the route opened around Millville in 1969 while the section bypassing Vineland was completed in the 1970s. Route 55 was completed north to Deptford in 1989. (Full article...)
