U.S. Route 1 (US 1) in Florida runs 545 miles (877 km) 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. The road is maintained by the Florida Department of Transportation (FDOT).
From its national southern terminus in Key West, US 1 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:
Among other designations, 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.
