About Biscayne Bay Islands

The causeways to Miami Beach run over a chain of man-made islands, and three of them belong to the City of Miami rather than to the beach. Biscayne Island and San Marco Island are the two westernmost of the six Venetian Islands, dredged up from the bay bottom by the Bay Biscayne Improvement Company and platted in the early 1920s. Watson Island lies on the MacArthur Causeway, which opened in February 1920 as the County Causeway. The Venetian Causeway that links the first two was dedicated in February 1926 and joined the National Register in 1989.

Averages are weighted as total dollars over total square feet. We calculate averages based on closed sales in the MLS for the past 12 months, as of October 21, 2026. Averages are based on properties that are listed or sold for $350,000 and greater. Additional reports at all price points are available here. Price-per-square-foot figures are rounded to the nearest dollar, up or down. Where fewer than 5 closed sales exist in the window, we report the count rather than an average.
