Florida Towns on US-1 and SR A1A, Fernandina Beach to Key West
Two Historic Roads on Parallel Paths
State Road A1A begins in Fernandina Beach at the Georgia state line on the St. Marys river and extends south 390 miles to Miami. A1A is the beach highway along the Atlantic Ocean.
U.S. Highway 1 comes into Florida across the St. Marys River and extends 547 miles to Key West. Its route takes you through older mainland towns that followed the extension of the railroad in the 1800s and 190s.
