US 1 Bridge Replacement Project From CR A1A to CR 707

The Florida Department of Transportation has replaced the S.R. 5/U.S. 1 Bridge over the Loxahatchee River/Intracoastal Waterway in the Town of Jupiter. The replacement bridge consists of two 11-foot travel lanes in each direction, 8-foot sidewalks and 7-foot bike lanes in both directions. Pedestrians are separated from traffic with permanent concrete barriers. The new bridge is a twin double-leaf drawbridge with up to 42 feet of vertical clearance and a navigable channel width of 125 feet. The new bridge features a concrete bridge deck to reduce traffic noise, a new tender house and pedestrian overlooks. For the 21-month bridge closure and detour, temporary intersection improvements consisted of additional turn lanes constructed at: U.S. 1 at S.R. 706/Indiantown Road, Alternate A1A and S.R. 706/Indiantown Road and U.S. 1 and Alternate A1A/Beach Road. Permanent intersection improvements also were constructed at Alternate A1A and Old Dixie Highway. Intelligent Transportation System devices were installed to improve traffic flow.
