FDOT will be performing a foundation test in advance of the upcoming US-1 Jupiter Bridge Replacement project. The test will consist of placing one concrete pile in Loxahatchee River adjacent to the northeast side of the US-1 Jupiter Bridge. The anticipated duration of the foundation testing is from December 15th through December 19th. The testing will not affect vehicular traffic on the existing bridge or vessels from accessing the navigational channel. Please click here to view the press release that includes more information.

The existing four lane SR-5/US-1 Federal Highway Bridge over the Loxahatchee River/Atlantic Intracoastal Waterway (AICW), constructed in 1958 and includes a 116-ft twin double-leaf bascule span over the main channel, is to be replaced due to a combination of structural deficiencies and functional obsolescence. The existing bridge typical section includes two eleven-foot inside travel lanes, two twelve-foot outside travel lanes, and two-foot outside shoulders. Dedicated sidewalks and bicycle lanes are not provided, nor does a barrier exist between vehicles and pedestrians traveling along the two-foot wide raised curb along the bridge. Adjacent historic properties include the World War II Married Men’s Quarters Building and the Jupiter Inlet Lighthouse. The bridge will be replaced with a new bridge that has 35 feet of vertical clearance and 125 feet of horizontal clearance. Seven-foot buffered bicycle lanes and eight-foot sidewalks will be provided on both sides.

The Jupiter US 1 Bridge Project has been approved by the Florida Department of Transportation (FDOT). FDOT granted Location and Design Concept Acceptance (LDCA) for the Project Development and Environment (PD&E) Study prepared for the bridge project on March 8, 2019.
