U.S. Route 1 in Florida

U.S. Route 1 (US 1) in Florida runs along the state's east coast from Key West to its crossing of the St. Marys River into Georgia north of Boulogne, and south of Folkston. US 1 was designated through Florida when the U.S. Highway System was established in 1926.

US 1 runs in the state of Florida, and is maintained by FDOT. From it's national southern terminus in Key West, it carries the Overseas Highway, the Keys main highway north to the mainland, entering South Florida. From South Florida to Jacksonville, US 1 runs close to the coastline of the Atlantic Ocean and the Intracoastal Waterway, generally east of I-95 and west of State Road A1A, running roughly parallel with both roads. North of Jacksonville, US 1 curves inland towards the St. Mary's River as it enters Georgia.

As is the case with all Florida roads with Federal designations, the entirety of US 1 has a hidden Florida Department of Transportation designation: State Road 5 south of Callahan (except for as SR 805 in Palm Beach County); State Road 15 north of Callahan. US 1 is a designated Blue Star Memorial Highway along its entire route through the state. Markers are placed at various locations, including one in Rockledge, Florida and Fort Lauderdale, Florida. State Road A1A runs next to the Atlantic Ocean, roughly parallel to US 1 for much of its path through Florida.
