FDOT Project on the US1 Bridge

The Florida Department of Transportation (FDOT) will replace the U.S. 1 Bridge FDOT US1 bridge rendering Opens in new windowover 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. It will also feature a concrete bridge deck to reduce traffic noise, a new tender house and pedestrian overlooks. 

In preparation for a 20-month bridge closure and detour, temporary intersection improvements that consist of additional turn lanes will occur at: U.S. 1 at Indiantown Road, Alternate A1A and Indiantown Road and U.S. 1 and Alternate A1A/Beach Road. Permanent intersection improvements also will occur at Alternate A1A and Old Dixie Highway. Intelligent Transportation System devices will be installed to improve traffic flow.
