There are several urban myths about the selection of Virginia Key by county officials, each with a kernel of truth – but there was an historic connection of at least several decades’ standing. A 1918 survey map of the "Abandoned Military Reservation" on Virginia Key located a "Negro Dancing Pavilion" on the island's southeastern shore of the "colored-only" beach. From 1945 to 1947, Miami's Blacks traveled to the beach exclusively by boat – public and private. The opening of the Rickenbacker Causeway in 1947 connected Virginia Key and Key Biscayne with the mainland and vehicular travel began.
