SR 80 Southern Boulevard Bridge Replacement

This project consists of the replacement of the existing bridge over the Intracoastal Waterway and Lake Worth Lagoon between West Palm Beach and Palm Beach. The new bridges will each carry one lane of traffic in each direction, have 6-foot-wide sidewalks in each direction, and 10-foot-wide paved shoulders with 7-foot-wide bike lanes. The new bridge over the Intracoastal Waterway will be a drawbridge with a vertical clearance of 21 feet. The new bridge over Lake Worth Lagoon (tide relief bridge) will be a low level, fixed bridge similar to the existing bridge. The project also includes reconstruction and paving of the roadway approaches and causeway. Estimated total cost of construction is $93 million and is expected to be completed in November of 2020.
