Background

The Florida Department of Transportation (FDOT) inspectors advised that three interior Duck Key bridges that affect Harbour Island, Plantation Island, and Yacht Club Island need to be replaced. The Bimini Bridge, constructed in 1955, was already scheduled for replacement. County staff accelerated the bidding process for the Bimini Bridge with an estimated contract period to complete the replacement is 18 months. The County approved a strengthening plan for the existing north lane of the Bimini Bridge. This will allow one lane of traffic to cross while the south side of the permanent bridge is being constructed. The strengthened section will allow Florida legal weight limits to cross without a reduced weight load. Bimini Bridge affects Harbour, Plantation, and Yacht Club islands and also connects to the Harbour Drive and Seaview bridges.
