SR A1A North Causeway Bridge

Welcome

The SR A1A North Causeway Bridge is a movable bridge located in St. Lucie County that was constructed in 1963. It spans over the Intracoastal Waterway (ICWW) connecting the barrier island to the mainland in the City of Fort Pierce. In March 2016 the bridge was structurally inspected and received ratings providing justification for replacement.

As a result of the completed planning study, a high level fixed bridge has been selected as the preferred alternative. The new bridge will provide a minimum vertical navigational clearance of 85ft.

The new bridge will cross over the FEC Railroad corridor and Old Dixie Highway. The project also includes improvements to Old Dixie Highway and the extension of Juanita Avenue between US 1 and Old Dixie Highway.
