About the Project

Project Overview

The purpose of the project is to replace the existing bascule bridge to address structural deficiencies, improve traffic operations, improve bicycle and pedestrian safety and improve the vertical and horizontal clearances at the navigable channel. The existing bridge, constructed in 1958, carries two lanes of traffic in each direction and has 2-foot shoulders with no dedicated sidewalks or bicycle lanes provided. The replacement bridge will include two 11-foot travel lanes in each direction, sidewalks, bike lanes, traffic railing barrier, drainage system improvements and decorative lighting. New signage and pavement markings will be installed throughout the project. The increased vertical (up to 42 feet) and horizontal (125 feet) clearances are anticipated to decrease bridge openings by approximately 44 percent, reducing delays to vehicles and marine traffic. Intelligent Transportation System devices will be installed to improve traffic operations. Intersection improvements to mitigate traffic impacts will occur at: US 1 and SR 706/Indiantown Road, Alternate A1A and SR 706/Indiantown Road, US 1 and Alternate A1A/Beach Road, and Alternate A1A and Old Dixie Highway. Minor bridge repairs will occur on the Alternate A1A bridge over the Loxahatchee River.
