Talk of a bridge to
Key Biscayne, Florida inspired by the bridges connecting
Miami to
Miami Beach, started in 1926. The northern two-thirds of Key Biscayne was owned by
William John “W.J.” Matheson, who had established a
coconut plantation on the island. In February 1926 Matheson entered into an agreement with land developer D. P. Davis to develop and re-sell the northern half of Key Biscayne, including all of what is now Crandon Park and about half of the present Village of Key Biscayne. Later in 1926 the City of
Coral Gables incorporated with Key Biscayne included in its boundaries. There were dreams of a bridge to the island, making Key Biscayne the seaside resort for Coral Gables that Miami Beach had become for Miami. In March 1926, the
U.S. government auctioned off some lots on Key Biscayne that had been retained when the rest of the island was transferred to the State of Florida. The Mathesons wanted to have clear title to all of their land, and determined to outbid other interested parties for the land. They ended up paying US$58,055 for a total of of land, a record price per acre for the auction of U.S. government land up to that date. Then, on September 18, 1926, the
1926 Miami Hurricane crossed over Key Biscayne on its way to Miami. While there were no deaths on the island, most of the buildings on Key Biscayne were destroyed or badly damaged, and many of the plantings were lost, including half of the coconut trees. D. P. Davis was not able to meet his end of the contract; he declared bankruptcy and then disappeared en route to Europe by ship. The Florida Land Boom was over, as were plans for a bridge. William Matheson died in 1930, leaving the island to his children. There was a flurry of interest in 1939, when the
U.S. Navy approved a proposal to develop Virginia Key as an
air base and
sea port. There was even talk of putting an air base on the north end of Key Biscayne, as well. In 1940 William Matheson's heirs donated of land, including two miles (3.2 km) of beach on the
Atlantic Ocean on the northern end of Key Biscayne to Dade County to be used as a public park (Crandon Park). The county commissioner who negotiated the gift, Charles H. Crandon, had offered for the county to build a causeway to Key Biscayne in exchange for the land donation. Planning for the air and sea complex on Virginia Key was still proceeding, and construction on a causeway to Virginia Key started in 1941. The
Attack on Pearl Harbor and the entry of the United States into
World War II stopped all work on the causeway and the development of Virginia Key. After the end of World War II, Crandon pushed on with the project. He got financier
Ed Ball to buy $6 million worth of bonds financing the construction of the causeway. Land for the
toll plaza and the causeway entrance was bought from the estate of
James Deering. Fill dredged from the bottom of Biscayne Bay and dug from the mainland were used as both the
road bed and public
beach areas, both to the west of Virginia Beach and on the southern reaches of the island. In November 1947 the Rickenbacker Causeway – of bridges and of roadway on fill – finally opened. In the late 1960s and 1970s the sites along the Rickenbacker Causeway continued to increase in popularity. After increasing in the mid 1960 because of the American television series
Flipper, attendance to the Miami Seaquarium soared in 1968 when it started to display Hugo, its first
killer whale (two years later, Lolita became their second. The two killer whales performed together until Hugo's death in 1980). Shortly afterward, Planet Ocean, a themed tourist attraction, opened its doors. Newly integrated beaches were often crowded; the causeway near the
drawbridge across the Intracoastal Waterway, and bridgeway near the mainland, became favorite fishing spots. But popularity had a price: by 1980 it became evident that the concrete and steel structures supporting the roadway west of Virginia Key needed replacement. Five years later, the high-rise William Powell Bridge and new bridging nearest the toll plaza were built and opened at a cost of $27 million. With exception of the drawbridge (which was removed) the old bridging was left intact to serve as
fishing piers. In 2011, the West Fishing Pier was demolished. Since the opening of the new bridge, the
MAST Academy took over the site of the defunct Planet Ocean (the theme attraction closed in 1991); the Virginia Key site of the City of Miami's garbage dump became a
Superfund site for cleanup; the beach at Bill Baggs Cape Florida State Park was gaining in popularity; but the
Miami Marine Stadium has been virtually abandoned and the Miami Seaquarium has had a series of setbacks, from being devastated by hurricanes
Andrew (1992) and
Wilma (2005) and being prevented from expanding by threats of legal action by the newly incorporated Village of
Key Biscayne; the Seaquarium eventually closed on October 12, 2025. On the other hand, the entire length of the causeway, plus Crandon Boulevard, have become part of a popular
bicycling route from Key Biscayne to Florida City. == References ==
