Project Description

The  4.1 mile US 1 Bridge Replacement Project will replace the existing bridge over the Loxahatchee River and Intracoastal Waterway in the Town of Jupiter from CR A1A to CR 707/Beach Road. The replacement bridge will consist of two 11-foot travel lanes, 7-foot bicycle lanes and 8-foot sidewalks in each direction. The new bridge will have up to 42 feet of vertical clearance, and the navigable-channel width will be increased to 125 feet. An intelligent transportation system will be installed to improve traffic flow. Permanent intersection improvements will occur at Alternate A1A and Old Dixie Highway. In addition, there will be minor repairs to the Alternate A1A bridge over the Loxahatchee River. Construction began on October 18, 2021.   

One outside lane in each direction will be closed continuously on the Alternate A1A bridge over the Loxahatchee River beginning Thursday, Nov. 18, until Wednesday, Dec. 22, for concrete repairs.
