Florida State Road 45


A major north-south highway extending almost the entire length of the Florida peninsula, State Road 45 is the unsigned Florida Department of Transportation designation of most of the current U.S. [Route 41 (Florida)|U.S. Route 41] in Florida. The southern terminus of SR 45 is an intersection with SR 90 in downtown Naples; the northern terminus is an intersection with U.S. [Route 441 (Florida)|US 441] in High [Springs, Florida|High Springs]. South of Causeway Boulevard near Tampa, SR 45 is also known as Tamiami Trail.
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.

State Road 45A

State Road 45A is the Venice Bypass, a segment along U.S. Route 41 east of Tamiami Trail in Venice, which was originally part of US 41 until 1965 when that segment was redesignated as US 41 Bus after the Intracoastal Waterway was dredged through Venice by the U.S. [Army Corps of Engineers] in 1964. The route begins near Shamrock Boulevard in Venice Gardens and terminates at Venetia Bay Boulevard in the Eastgate section of Venice.
