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.
