State Road A1A North Causeway Bridge

under construction

The new North Causeway Bridge in Fort Pierce is a fixed span bridge over the Indian River Lagoon, replacing the existing drawbridge built in 1963. It provides a more reliable connection between S.R. A1A and U.S. 1, spanning the Florida East Coast Railway, Old Dixie Highway, and the Intracoastal Waterway, eliminating bridge openings for marine traffic and reducing delays for motorists. The bridge features one 12-foot-wide travel lane in each direction, navigational clearances of 85 feet vertical and 125 feet horizontal, barrier-protected sidewalks and shared-use paths, buffered bicycle lanes, and an observation deck beneath the west side of the structure. Additional improvements include shared-use paths, new access roads, and extended avenues connecting to Old Dixie Highway.
