SR 5/US-1 Federal Highway Bridge Project Development & Environment (PD&E) Study
The SR 5/US-1 Federal Highway Bridge (Bridge Identification Number 930005) is a low-level bascule bridge originally constructed in 1958 and located in the Town of Jupiter, Palm Beach County, Florida. It spans over Loxahatchee River and the Atlantic Intracoastal Waterway (ICWW) connecting communities within the Town of Jupiter to the south and the Village of Tequesta to the north.
In September 2014 the bridge was structurally inspected and received an unsatisfactory sufficiency rating providing justification for replacement. The deck and superstructure and of the bridge obtained satisfactory ratings, yet the corrosive condition of the substructure deemed the bridge structurally insufficient. The vertical clearance between mean high water (MHW) and the bottom of the superstructure of the existing bridge is 25 feet which meets the United States Coast Guard’s (USCG) 21-foot vertical clearance requirement. However, the existing horizontal clearance does not meet the USCG 125-foot requirement, with only 90 feet clearance between fenders.
The current bridge is functionally deficient because it lacks bicycle and pedestrian accommodations which is a concern as pedestrians and bicyclists cross the bridge. Based on various studies conducted by the Florida Department of Transportation (FDOT) over the last several years, project stakeholders including the Town of Jupiter and the Palm Beach Metropolitan Planning Organization (MPO) expressed the need to provide dedicated facilities for pedestrian and bicycle traffic. Based on the bridge inspection and engineering evaluation it is not feasible to add these facilities to the existing bridge structure.
