Southern Blvd. Bridge rendering

Florida is making plans to replace Southern Boulevard Bridge, connecting Palm Beach to West Palm Beach.

The Florida Department of Transportation unveiled its plans for replacing the Southern Boulevard Bridge over the Intracoastal Waterway in West Palm Beach while it's still in the midst of building the replacement for the Flagler Memorial Bridge.

This time, the state hopes to avoid the pitfalls that have come with replacing the Flagler bridge. The state transportation department plans to build a temporary bridge to the north of the existing Southern Boulevard bridge to keep traffic moving between the mainland and the island.

Here's what's planned:

  • A two-lane bridge with 10-feet-wide shoulders to accommodate bicyclists and 6-feet-wide sidewalks in both directions;
  • A 21-foot clearance and a span of 125 feet; the old bridge has a 14-foot vertical clearance and an 80-foot span;
  • A smaller relief bridge to the east of the Southern bridge also is being replaced;
  • On the Post Memorial Causeway, there will enhanced parking areas, paved shoulders and new sidewalks; and;
  • There will be a new left-turn lane from the bridge onto Flagler Avenue.

Construction on the Southern Boulevard Bridge is scheduled to begin in the summer of 2016 just as work is finishing up on the new Flagler bridge. Flagler's construction is expected to be completed in late 2016.
