State Road 45 (SR 45) is a major north–south highway extending almost the entire length of the Florida peninsula. It is the mostly unsigned designation from the Florida Department of Transportation (FDOT) for most of the current U.S. Highway 41 (US 41) in the state. The southern terminus of SR 45 is an intersection with SR 90 in downtown Naples; the northern terminus is an intersection with US 441 (SR 25) in High Springs. South of Causeway Boulevard (SR 676) near Tampa, SR 45 is also known as Tamiami Trail.

SR 45 in South Seminole Heights, Tampa, south of SR 574 (April 8, 2006)

South and east of Naples, US 41 turns eastward as SR 90 as the Tamiami Trail crosses the Everglades on its way to Miami; north of High Springs, US 41 overlaps US 441 until their split in Lake City (from there US 41 continues to the Georgia border with the hidden SR 25 designation).
