Bradenton Beach was originally referred to as Cortez Beach since it was close to Cortez. Construction on a wooden bridge to the mainland would begin in the summer of 1921. The 1921 Tampa Bay Hurricane that October would destroy 80% of the bridge that was built up to that point. Despite a majority of the bridge being destroyed, it would later be completed sometime in June 1922; 8 months later. Bradenton Beach started to be known as it's present day name during the mid 1920s as the Florida land boom was occurring. Real estate developers saw this as a way to convince possible buyers that it was closer to Bradenton. Sometime in early 1926, a county bond was approved to build a wooden bridge linking Bradenton Beach to Longboat Key with the bridge being finished in August. However, the bridge was only open until October after a hurricane damaged it. On March 6, 1932 the bridge would be swept away during a high tide. It would not be replaced until 1957. A post office called Bradenton Beach has been in operation since 1941. Bradenton Beach would later be incorporated in 1952. The main wooden bridge to the island from Cortez would be replaced by a concrete one in 1957 as local residents wanted a stronger bridge. A parade lead by an elephant was hosted by the city to display it strength and to convince the local residents as well. To offset the cost of bridge, the local government made it a toll bridge until 1964 when it was reimbursed. Cars were charged 30¢ entering the island and no toll was put in place on those leaving the island.
