Treasure Island Causeway is a series of three bridges crossing Boca Ciega Bay between Treasure Island and St. Petersburg in Pinellas County, Florida. The bridge, which carries County Road 150 (CR 150), is owned and maintained by the City of Treasure Island, which used to charge all motorists $1.00 toll, until June, 2006, when the first span of the bridge was reopened with no toll booth.

That tax was eliminated in the spring of 2007. Treasure Island's ownership of the causeway in St. Petersburg was part of a land agreement entered into when these two cities were born: St. Petersburg's founding fathers purchased the Municipal Beach on the shores of the neighboring Gulf of Mexico community, Treasure Island, outside its own city limits to ensure that residents would have direct access to the Gulf of Mexico for generations to come.
