The Loop

State Road A1A is a north-south Florida State Road that runs along the Atlantic Ocean, from Key West at the southern tip of Florida, to Fernandina Beach, just south of Georgia on Amelia Island. It is the main road through most oceanfront towns. Part of SR A1A is designated the A1A Scenic and Historic Coastal Byway, a National Scenic Byway. A portion of A1A that passes through Volusia County is designated the Ormond Scenic Loop and Trail, a Florida Scenic Highway. It is also called the Indian River Lagoon Scenic Highway from State Road 510 at Wabasso Beach to U.S. Route 1 in Cocoa. A1A is famous worldwide as the center of beach culture in the United States, a scenic coastal route through most Atlantic coastal cities and beach towns, including the unique tropical coral islands of the Florida Keys. A1A also serves as a major thoroughfare through Miami Beach and other south Florida coastal cities. Other than SR A1A Alternate , only two other Florida state roads have begun with a letter: SR A19A , and SR G1A . The road was designated as State Road 1 in the 1945 renumbering, mostly replacing the former State Road 140 designation. The number reflected its location in the new grid as the easternmost major north–south road. About a year and a half later, in November 1946, the State Road Board resolved to renumber the route due to confusion with the parallel U.S. Highway 1. The new designation, A1A, was chosen to keep the number 1 in its place in the grid.The East Coast Greenway, a system of trails that connects Maine to Florida, travels along sections of State Road A1A.
