H&H is serving as the Engineer of Record for the replacement of the Jupiter Federal Bridge. During the preliminary design phase, H&H addressed the existing US-1/SR-5 Jupiter Federal Bridge’s structural and functional deficiencies over the Intracoastal Waterway from CR-A1A (Ocean Boulevard) Beach Road by studying vertical and horizontal alignment bridge replacement alternatives. The project incorporates intersection improvements and improving traffic functions at both ends of the approximately 2,960-foot long (0.56 mile) project corridor.
The new bridge configuration has an overall length of 915 feet. The main span over the navigation channel is a 267-foot-long twin double‐leaf trunnion-type bascule span. The south approach span unit is 480 feet long and includes three concrete spans (at 152, 160, and 168 feet) with a continuous deck. The approach span unit to the north has a single concrete span at 168 feet. The bridge will have a constant overall width of 100.5 feet that accommodates two 30-foot-wide roadways divided by a 19.5-foot-wide median. Each roadway will include two ADA 11-foot travel lanes, an 8-foot outside shoulder, with a seven-foot buffered bike lane. An 8-foot-wide sidewalk will be provided outboard each roadway, separated by a traffic railing and bordered by a pedestrian/bicycle railing.
The existing Jupiter Federal Bridge, originally constructed in 1958 (with a 116-foot movable span length) and recently deemed by FDOT to be functionally obsolete and structurally deficient, is a four-lane, divided, low-level bascule bridge that connects Palm Beach County’s Jupiter Inlet District and Tequesta communities.
