Bridge Closure Information

The Florida Department of Transportation has provided incentives / disincentives to the contractor to limit the detour’s duration. The contractor can receive up to $3.5 million if the detour ends in less than 20 months and one lane of traffic in each direction is open on the new bridge. The contractor faces a $35,000 per day penalty if the detour extends past 20 months. The contractor may earn an additional “no excuse” bonus of $1.5 million to open two lanes of traffic in each direction by November 2024.

Traffic will be detoured to Alternate A1A. See map below.

Intelligent Transportation System (ITS) devices have been placed along the detour route to allow 24/7 monitoring and active traffic management by the Florida Department of Transportation and Palm Beach County. These enhancements will improve travel times, alleviate congestion, allow real-time adjustments of traffic signal timing and allow advance notification to the public of traffic delays. A system that allows emergency vehicles to receive green lights at signalized intersections also has been deployed to reduce emergency response times.

 The following intersection improvements were constructed along the detour route to improve traffic flow:

• Alt A1A at Old Dixie Highway (permanent)
  • Shifting the intersection to the southwest
  • Adding a traffic signal
  • Lengthening the left-turn lane from northbound Alt A1A to northbound Old Dixie Highway
• US 1 at SR 706/Indiantown Road (temporary)
  • Three left-turn lanes from northbound US 1 to westbound SR 706 (two left-turn lanes currently)
• SR 706/Indiantown Road at Alt A1A (temporary)
  • Two left-turn lanes from southbound Alt A1A to eastbound SR 706 (single left-turn lane currently)
  • Two right-turn lanes from westbound SR 706 to northbound Alt A1A
• Alt A1A at US 1 (temporary)
  • Two right-turn lanes from southbound US 1 to westbound Alt A1A

Marine traffic will be maintained. However, occasional channel restrictions may occur.

Anticipated completion is early 2026.

The replacement bridge will have a wider section to accommodate sidewalks and bike lanes in each direction. The new bridge will consist of two 11-foot travel lanes in each direction as well as 8-foot sidewalks and 7-foot bikes lanes in both directions. The replacement bridge also will have a higher vertical profile.

Yes. The Coast Guard has approved a moratorium on bridge openings during the following hours: 7 a.m. to 9 a.m. and 4:30 p.m. to 6:30 p.m. Monday through Friday. This moratorium will be in place from March 13, 2023, to September 7, 2023
