SR 786 (PGA BOULEVARD) RECONSTRUCTION FROM SR 710 (BEELINE HIGHWAY) TO THE C-18 CANAL
Palm Beach County, FL
This high-visibility, award-winning project combined necessary roadway improvements with significant environmental sensitivity and wetlands expertise. The centerline grade was raised to alleviate roadway flooding, re-establish hydrologic connections associated with the Loxahatchee Slough and Grassy Waters Preserve, and provide wetland mitigation for impacts to federally protected species. WGI’s ATC’s on this project accelerated construction and reduced project costs by $745,000 for a winning bid. Our staff optimized water flows; reduced environmental impacts and future maintenance; and improved mobility during construction. Specifically, our design eliminated one acre of wetland impacts, improved wildlife passage under PGA Boulevard, reduced maintenance and project costs, and shortened the original construction schedule. The new bridge allows wildlife and recreational boaters to pass beneath while maintaining the waterway opening and a wildlife path adjacent to the channel. Its lower profile reduced environmental impact and increased durability. The team’s comprehensive design included a construction sequence that maintained the existing function of the facility for a resulting increase in function and safety. The project earned an Honor Award from the Florida Chapter of the Design-Build Institute of America.
