The corridor included approximately 1.5 miles of roadway improvements beginning at Manth Lane and a 0.75-mile bridge over the North Fork of the St. Lucie River, ending at the intersection with U.S. 1. The bridge traverses an environmentally sensitive area, which required minimization of wetland impacts and protection of the Savannas Preserve State Park. This project features unique architecture for the city's signature bridge, drainage design, utility coordination/ design, and extensive landscaping. The PD&E process took more than 10 years, leaving federal funding jeopardized and on the brink of expiration if they did not let for construction soon. To secure funding more quickly, the city used design-build to expedite the process. To minimize the environmental challenges, the team decided to design the bridge with geotechnical information that had been obtained from either land side approach intending to complete geotechnical investigations via temporary trestle during construction. This eliminated a separate permit to obtain geotechnical information.
