Florida Highways
Florida’s interstates, state highways and U.S. Highways are maintained by the Florida Department of Transportation.
Florida’s interstate highway system contains 1,473 miles (2,371 km) of highway, and there are 9,934 miles (15,987 km) of non-interstate highway in the state, such as Florida state highways and U.S. Highways.
Florida’s primary interstate routes include:
* I-4, which bisects the state, connecting Tampa, Lakeland, Orlando, and Daytona Beach, connecting with I-95 in Daytona Beach and I-75 in Tampa.
* I-10, which traverses the panhandle, connecting Jacksonville, Lake City, Tallahassee and Pensacola, with junctions with I-95 in Jacksonville and I-75 in Lake City.
* I-75, which enters the state near Lake City (45 miles west of Jacksonville) and continues southward through Gainesville, Ocala, Tampa’s eastern suburbs, Bradenton, Sarasota, Fort Myers and Naples, where it crosses the "Alligator Alley" as a toll road to Fort Lauderdale before turning southward and terminating in Hialeah/Miami Lakes having junctions with I-10 in Lake City and I-4 in Tampa.
* I-95, which enters the state near Jacksonville and continues along the Atlantic Coast through Daytona Beach Melbourne/Titusville, Palm Bay, Vero Beach, Fort Pierce, Port Saint Lucie, Stuart, West Palm Beach, and Fort Lauderdale before terminating in Downtown Miami, with junctions with I-10 in Jacksonville and I-4 in Daytona Beach.
Prior to the construction of routes under the Federal Aid Highway Act of 1956, Florida began construction of a long cross-state toll road, Florida’s Turnpike. The first section, from Fort Pierce south to the Golden Glades Interchange was completed in 1957. After a second section north through Orlando to Wildwood (near present-day The Villages), and a southward extension around Miami to Homestead, it was finished in 1974.
North-south state highways are all odd numbered, two-digit, with low numbers on the east coast and higher numbers on its west coast and in the panhandle. East-west state highways have three digits. They are low numbered in the north, high numbered in the south. County roads often follow this same system.
