TRANSPORTATION

The Florida Department of Transportation (FDOT) has begun a bridge rehabilitation and safety project along SR A1A/MacArthur Causeway East Bridge (bridge number 870077) from Terminal Island to Alton Road

WORK TO BE PERFORMED

• Repairing concrete elements under the bridge such as beams, columns, painting bridge steel spans and repairing the fender system and electrical components to the navigational bridge lighting
• Repairing elements on top of the bridge such as concrete deck replacement

LANE CLOSURE AND DETOUR INFORMATION
To do this work safely, it will be necessary to close travel lanes and establish detours at times. One continuous lane closure will occur in the westbound lanes followed by the eastbound lanes for approximately nine months.

On Thursday, March 7, the contractor began work in the center eastbound lane of the causeway. The middle eastbound lane will be continuously closed for approximately two months while workers replace the bridge deck in this area. A second eastbound lane closure will occur as needed, from 10 p.m. to 6 a.m. 

On Sunday, April 14, the westbound temporary barrier wall in the center eastbound lane was extended. Eastbound drivers in the left lane of the causeway will be restricted to only turning into Alton Road, while drivers in the right lane will be able to only enter Miami Beach.

Daytime and nighttime work will be performed both on top and underneath the bridge. At least one eastbound and one westbound travel lane will remain open at all times.

Lane closure and project information will be posted weekly on the department’s website.
