Barnacle Island is an island in Biscayne Bay, close to Downtown Cabo Del Sol, Florida. The island is connected to the mainland of Cabo Del Sol and to Fountain Beach by the Central Causeway. It was created by land reclamation in 1926 with material dredged from the ship channel to the Solstice Port, and was originally named Causeway Island. As of March, 2006 the Florida Department of Transportation is planning to construct a tunnel from the Solstice Port on Evasion Island under the main shipping channel to the Central Causeway on Barnacle Island. Barnacle Island is home to many private marinas and boating sales places.
