Florida State Road 10

State Road 10 (FL 10) is a 394.524 mile-long (634.925 km) major east–west state highway in the U.S. state of Florida. Mostly unsigned in favor of U.S. Highway 90 (US 90), it runs from the Alabama state line (Perdido River) to State Road A1A (FL A1A) in Atlantic Beach near the Atlantic Ocean. The only sections that are not signed as US 90 are north of Pensacola, where US 90 uses FL 10A and FL 10 is signed as U.S. Highway 90 Alternate, and the 15.087 miles (24.280 km) of its own remaining route, east of south Jacksonville, where US 90 uses unsigned FL 212 (Beach Boulevard), and FL 10 carries Atlantic Boulevard and is the only signed section of FL 10.

Route description

The only signed section of FL 10 is in Jacksonville and Atlantic Beach. Signage begins at the interchange with Interstate 95 (I-95) and U.S. Highway 1 (US 1), where US 1 splits to the south. There is a signed concurrency east to the split with US 90. Where US 90 and FL 10 split, FL 10 is known as Atlantic Boulevard, while US 90 is known as Beach Boulevard (unsigned State Road 212) to Jacksonville Beach.

About a mile (2 km) before the east end of FL 10, at the east end of the bridge over the Intracoastal Waterway, FL A1A (Mayport Road) joins from the north. There is an incorrect overhead sign that says the Mayport Road flyover ramp is FL 101, however the FL 101 designation does not begin on Mayport Road for another 2.3 miles (3.6 km). At the exit, Mayport Road is FL A1A. The two roads run concurrently on Atlantic Boulevard to Third Street, where FL 10 ends and FL A1A turns south. (Atlantic Boulevard continues several blocks further as a local road to the beach.)
