Florida State Road 5

State Road 5 (SR 5) is a mostly-unsigned state highway in the state of Florida. It is mainly signed as US 1 from its south end in Key West, Florida to Jacksonville, Florida, and US 17 from Jacksonville to the Georgia state line at the Saint Marys River. US 1 is SR 15 northwest from Jacksonville.

However, from northern Lantana through Lake Worth to Belvedere Road in West Palm Beach, SR 5 is separate from US 1, which runs to the west on the older but wider Dixie Highway. Here, SR 5 runs along a road named Olive Avenue.

SR 5 uses the parallel Olive Avenue from just north of County Road 812 (Lantana Road) in Lantana until Belvedere Road in West Palm Beach, where it turns west one block to rejoin Dixie Highway and US 1. Olive Avenue and Dixie Highway are parallel and extremely close to each other for this entire length. Olive Avenue is also signed as Federal Highway, but this name is not used as much.

Until around 2004, Olive Avenue carried northbound US 1 (and SR 5) north from Dixie Highway (new US 1 / SR 805) to SR A1A. In 2004, US 1 was re-routed onto Dixie Highway without SR 5. Afterwards, FDOT started periodically relinquishing SR 5 in fragments between July 1, 2004 and April 7, 2011. FDOT has relinquished all of former SR 5 in the city of West Palm Beach. Therefore, SR 5 has a gap starting at the West Palm Beach-Lake Worth city line, and resumes at the US 1 intersection with Belvedere Road in West Palm Beach.

State Road 5A, known locally as Nova Road, is a north-south road that runs 15.613 miles (25.127 km) through the cities of Port Orange, Daytona Beach, South Daytona and Ormond Beach in Volusia County. It serves as an alternate route to US 1 (SR 5), which runs to the east of SR 5A.

County Road 5A (also known as Stuckway Road) is a 1-mile (1.6 km) spur route of State Road 5 (U.S. Route 1.) It is the northernmost Brevard County route, and also the shortest. From Interstate 95, it provides access to Oak Hill and Scottsmoor, the northernmost town in Brevard. However, at its eastern terminus, it isn't in the town limits of Scottsmoor. Geographically, it is bounded by Volusia County to the north, and Aurantia to the south. The western terminus is with an interchange with Interstate 95 (exit 231), although Stuckway Road continues west as a dirt road. The eastern terminus is with an intersection with U.S. Route 1/State Road 5 near Scottsmoor.

State Road 5F is the unsigned designation for the Southeast 2nd Street and Southeast 2nd Avenue frontage road in Downtown Miami. The road runs 0.128 miles (0.206 km) from Southeast 3rd Avenue to the Downtown Distributor and is a one-way southbound street. SR 5F runs in the same right-of-way as US 1 (SR 5) and is separated only by a concrete curb.

State Road 5S is the unsigned designation for both Yacht Club Drive and Gilberts Resort Drive in Key Largo, running 0.246 miles (0.396 km) and 0.524 miles (0.843 km) respectively. The roads serve as access roads for motorists on US 1 (SR 5) as well as destinations for Gilbert's Resort & Marina and the Anchorage Resort & Yacht Club.
