Florida State Road 1

**State Road 1** (**FL 1**) was the original Florida State Highway designation that ran across the Atlantic Ocean prior to 1945 and 1946. After the 1945 Florida State Road renumbering, the route has changed to State Road A1A to avoid common confusion to State Road 1 itself and U.S. Highway 1 (US 1) and State Road 1 has been removed.

The number "1" reflected its location in the old 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.
