Traveling 545 miles within the state, U.S. 1 is the longest route in Florida. With origins in Downtown Key West, U.S. 1 follows the Overseas Highway northeast to link the Florida Keys chain of islands with Miami-Dade County at Florida City. There U.S. 1 succumbs to heavy development as a local route northward through Homestead to Kendall, Coral Gables and Miami.
A 2013-relocation moves U.S. 1 away from Brickell Avenue onto the first two miles of Interstate 95 in Miami. The US route turns east from I-95 along the Downtown Distributor (SR 970) to rejoin its surface alignment along Biscayne Boulevard. North from there, U.S. 1 parallels Interstate 95 for the remainder of its path along the east coast of Florida. Often times the business route for the city it serves, U.S. 1 travels slowly through North Miami, Hollywood, Fort Lauderdale, West Palm Beach and Jupiter through South Florida. A brief reprieve from development takes the highway northward to Hobe Sound and Stuart, where it again travels as a commercial arterial.
North through Port St. Lucie and Fort Pierce, U.S. 1 reaches the Space Coast from Vero Beach to Cocoa and Titusville. This stretch hugs the Intracoastal Waterway to Cape Canaveral as either a divided highway or commercial arterial. North of Mims, U.S. 1 becomes rural ahead of Edgewater and New Smyrna Beach.
Within Volusia County, U.S. 1 joins New Smyrna Beach, Port Orange, Daytona Beach and Ormond Beach mostly as a business route. Having stayed east of Interstate 95 since Exit 2A, the US route and freeway trade places beyond Ormond Beach, with U.S. 1 veering inland to Bunnell. Remaining rural, U.S. 1 crosses paths with I-95 again en route to St. Augustine.
North from Florida's oldest city, U.S. 1 again turns away from the Atlantic Ocean to another meeting with Interstate 95 at Southside Jacksonville. The route becomes an urban arterial there en route to the Main Street Bridge with U.S. 90 into Downtown. An Alternate route for U.S. 1 encircles central Jacksonville mostly as a freeway while U.S. 1 bisects the central business district along Main Street.
U.S. 1 overtakes Martin Luther King, Jr. Parkway west from Main Street and U.S. 17 to again cross Interstate 95 en route to an overlap with U.S. 23. U.S. 1 & 23 take New Kings Road northwest from Jacksonville to Callahan in Nassau County, where U.S. 301 ties in for a three-way overlap to Hilliard and Folkston, Georgia.
