Spanish River Boulevard is a short east–west highway in Boca Raton, Palm Beach County, Florida. The eastern 0.5 miles (0.80 km) is signed as State Road 800 (SR 800), though the western segment was formerly SR 800 as well. The western terminus of the boulevard is at Military Trail, but the state route does not begin until Federal Highway. Both the state route and the road itself terminate at Ocean Boulevard near the Atlantic Ocean shoreline at the northeastern corner of Spanish River Park, near Highland Beach.

U.S. Highway 1 (US 1) in Florida runs 545 miles (877 km) along the state's east coast from Key West to its crossing of the St. Marys River into Georgia north of Boulogne and south of Folkston. US 1 was designated through Florida when the U.S. Numbered Highway System was established in 1926. With the exception of Monroe County, the highway runs through the easternmost tier of counties in the state, connecting numerous towns and cities along its route, including nine county seats. The road is maintained by the Florida Department of Transportation (FDOT).
