context_page_description: U.S. Highway 1 in Florida runs 545 miles 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 United States Numbered Highway System was established in 1926. The road is maintained by the Florida Department of Transportation.
  From its national southern terminus in Key West, US 1 carries the Overseas Highway– the Keys main highway –north to the mainland, entering South Florida. From South Florida to Jacksonville, US 1 runs close to the coastline of the Atlantic Ocean and the Intracoastal Waterway, generally east of Interstate 95 and west of State Road A1A, running roughly parallel with both roads. North of Jacksonville, US 1 curves inland towards the St. Mary's River as it enters Georgia.
  As is the case with all Florida roads with national designations, the entirety of US 1 has a hidden FDOT designation:
context_section_description: As US 1 enters Palm Beach County and Boca Raton, it forms the western boundary to Royal Palm Yacht and Country Club, meeting with the northern terminus of the southern section of State Road 811. It passes through the heart of Boca Raton, becoming a divided road with three lanes each, becoming the eastern terminus of State Road 808, as well as intersecting State Road 800, and becoming the eastern terminus of State Road 794. US 1 then enters Delray Beach, becoming a one-way pair just north of Linton Boulevard, and meets State Road 806 in central Delray Beach. US 1 becomes a divided highway again, entering Boynton Beach, State Road 804 runs concurrent for 2 blocks, providing access to local beaches at Ocean Ridge via the Intercoastal Waterway. At the city limits of Lake Worth and Lantana, just north of Lantana Road, US 1's hidden designation, State Road 5 splits and runs parallel to US 1 a few blocks to the east. In central Lake Worth US 1 intersects State Road 802. Entering West Palm Beach, it first intersects State Road 882, followed by US 98/State Road 80.
  At Belvedere Road, it meets the northern end of State Road 5. In central West Palm Beach, it intersects State Road 704, where US 1 becomes a one way pair through the heart of West Palm Beach. A mile north of SR 704, A1A begins running concurrent with US 1. At Palm Beach Lakes Boulevard, the one way pair ends for US 1, continuing north for 11 blocks, until it hits 23rd/25th street, becoming a one way pair for 4 blocks, as US 1 moves two blocks west as it moves north. US 1 leaves West Palm Beach and enters Riviera Beach via a bridge over the Port of Palm Beach. In Riviera Beach, US 1's concurrency with SR A1A ends at State Road 708. In North Palm Beach it meets the eastern terminus of State Road 850 and State Road 786, where SR A1A becomes concurrent with US 1 for about 1.25 miles before splitting off at the southern end of Juno Beach. In Jupiter it intersects State Road 706, and has another concurrency with SR A1A just south of the Jupiter Inlet. Entering Tequesta at the northern end of the inlet, US 1 then meets up with the northern terminus of the northern portion of SR 811, and leaves Palm Beach County north of County Line Road.
