SR A1A North Causeway Bridge over ICWW St. Lucie County, Florida Client Florida Department Transportation District 4 Donovan Pessoa 954-777-4466 Start / Completion Date 2016-2019 Project Value $50,000,000 Hardesty & Hanover is providing engineering design services for the replacement of SR A1A North Causeway Bridge. Scope of services includes bridge design, geotechnical, drainage, hydrogeology, lighting, signalization, signage, paving marking, utility/railroad/marine coordination, public involvement, maintenance, control and protection of vehicular and marine traffic, as well as additional roadway design services which will address adjacent state, frontage and access roads and railway crossings affected by the project. Constructed in 1963, this movable bascule bridge spans over the Intracoastal Waterway (ICWW) connects the barrier island to the mainland in the City of Fort Pierce. In March 2014, the bridge was structurally inspected and found to be structurally deficient and functionally obsolete. The PD&E Study is currently underway to evaluate bridge replacement alternatives to resolve the structurally-deficient conditions and enhance regional mobility. It is likely that a high-level fixed bridge with improved safety for pedestrians and bicyclists and improved traffic operation will be deemed the most viable option. The preferred horizontal alignment of the replacement bridge is just north of the existing structure. The west end tie-down of the new bridge will be at US-1 and the east end tie-down will be near the North Causeway Island Park. The design will maintain local US-1 access beneath the new bridge spans via an extension of Juanita Avenue to Old Dixie Highway. New roadways for traffic crossing the FECRR to the marina will be either designed directly beneath the new bridge or parallel to the new bridge piers. F-23
