Former U.S. 1 Business - St. Augustine

Decommissioned in 2022 when a portion of the route was transferred from Florida Department of Transportation (FDOT) maintenance to the city of St. Augutine, U.S. 1 Business was the lone business route for U.S. 1 in the state of Florida. Prior to its removal, the loop was state maintained from the south end at U.S. 1 (Ponce de Leon Boulevard) and King Street (CR 214) for 3.2 miles to SR 16 (Picolata Street). SR 5A measures 2.737 miles along the course of U.S. 1 Business, utilizing King Street, a one way couplet with Cathedral Place west and Cordova Street south, Avenida Menendez, S Castillo Drive and San Marco Avenue. This includes a 1.318 mile concurrency with SR A1A from Cathedral Place and the Bridge of Lions in Downtown St. Augustine to May Street beyond Uptown. The northernmost 0.51 miles of U.S. 1 Business along San Marco Avenue was unsigned County Road 5A.

A $9.5 million improvement project underway from Fall 2017 to late 2019 September 2021 reconfigured U.S. 1 Business (San Marco Avenue) at the back to back intersections with West San Carlos Avenue and SR A1A (May Street) in St. Augustine. Utilizing a pair of jughandles, the redesign consolidated the adjacent intersections, addressing congestion by coordinating traffic signal phasing. Pedestrian improvements included the addition of a HAWK signal across May Street.¹
