The Venetian Islands are a chain of six man-made islands in Biscayne Bay that belong to the cities of Miami and Miami Beach, Florida. The islands are, from west to east: 1) Biscayne Island (Miami) with 20+ dry-lots and 20+ waterfront homes as well as a few mid and high-rise condos in the west and south side of the island. 2) San Marco Island (Miami) is exclusively single family homes with 20 dry-lots and 40+ waterfront residences. 3) San Marino Island (Miami Beach) is exclusively single family homes with 30+dry-lots and 50+ waterfront residences. 4) Di Lido Island (Miami Beach), the largest of all, is exclusively single family homes with 70 dry-lots and 90+ waterfront residences.5) Rivo Alto Island (Miami Beach) is exclusively single family homes with 40+ dry-lots and 60+ waterfront residences; and 6) Belle Isle (Miami Beach) with mid-rise and high-rise condos, school, hotel and more it is the most densely populated of the group.
The islands are connected by bridges from the Miami mainland to Miami Beach. The original wooden toll bridge (called the Collins Bridge) at the time it was completed in 1913 was the longest wooden bridge in the world spanning a total length of 2½ miles and provided a critical link to the newly established city of Miami Beach, formerly accessible only by a ferry service.
The original wooden causeway was replaced in 1925 by a series of arch drawbridges and renamed the Venetian Causeway. Today, the causeway is a popular stretch for people to jog, ride bikes, walk dogs and stroll.
