Ottawa Road 174 Shield

Ottawa-Carleton Regional Road 174 Shield

The city of Ottawa, Ontario, Canada maintains many regional roads, like most counties and regional municipalities in Southern and Eastern Ontario. The regional road system was created by the Regional Municipality of Ottawa-Carleton (RMOC) and managed by the RMOC until 2001. In 2001, when all six cities, four townships, and one village within the former RMOC amalgamated to form the new city of Ottawa, responsibility of the regional road system was transferred to the new city of Ottawa, and they became today's “Ottawa roads”.

In general, even-numbered routes run east-west and odd-numbered routes run north-south. Also, the lowest-numbered routes are generally found in the southern part of the city for even (east-west) numbered routes, and in the western part for odd (north-south) numbered routes. This pattern, however, has many exceptions. As more roads were added to the numbered-road system, the availability of numbers decreased and consequently, the numbering pattern had to be broken.

Ottawa Road 30 Shield

In smaller communities and rural areas the numbered roads are, for the most part, adequately signed with trapezoid-shaped signs with rounded corners, which are often referred to as "flowerpots" due to the shape of the sign. Older signs installed prior to 2001 have the legend "Ottawa-Carleton" at the top with the route number underneath. Newer signs installed after 2001 use the legend "Ottawa" or simply the "O" portion of the city's wordmark. Most numbered-road signs are not marked with directional tabs indicating the direction of the road (i.e. North, South, East, West), but where these appear, they are always printed in both English and French.

Most numbered roads in the urban areas of Ottawa are not signed with route numbers, despite having official route numbers and being listed on many maps with these numbers. Ottawa's city council adopted an updated route-numbering policy in 2005, under which road numbers are no longer posted inside the Greenbelt except for significant roads such as Ottawa Road 174, a former provincial highway, which is now usually known as "The 174". This effectively makes most Ottawa Roads within the greenbelt useful only for the City's internal purposes, not for wayfinding, as they are not signed. This is especially the case for Ottawa Roads 70, 78, 82, 105, and 113 which have little to no public record, due to the fact that they were likely numbered after numbering was discontinued in the downtown core.

During the mass downloading of Ontario's provincial highways onto regional authorities in 1997 and 1998, the former Regional Municipality of Ottawa-Carleton was given responsibility over former Highways 16, 31, 44, the section of 17 east of Highway 417 and the section of 15 downloaded to the Region. These former highways became known as Regional Roads (subsequently Ottawa Roads) 73, 31, 49, 174 and 29, respectively.
