US 1 Bridge Replacement Project From CR A1A to CR 707

Project At-A-Glance

The Florida Department of Transportation will replace the SR 5/US 1 Bridge over the Loxahatchee River/Intracoastal Waterway in the Town of Jupiter. The replacement bridge will consist of two 11-foot travel lanes in each direction, 8-foot sidewalks and 7-foot bike lanes in both directions. Pedestrians will be separated from traffic with permanent concrete barriers. The new bridge will be a twin double-leaf drawbridge with up to 42 feet of vertical clearance and a navigable channel width of 125 feet. The new bridge also will feature a concrete bridge deck to reduce traffic noise, a new tender house and pedestrian overlooks. For the 20-month bridge closure and detour, temporary intersection improvements that consist of additional turn lanes were constructed at: US 1 at SR 706/Indiantown Road, Alternate A1A and SR 706/Indiantown Road and US 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.
