completed. With loans from the Lummus brothers, Collins had begun work on a 2½-mile-long wooden bridge, the world's longest wooden bridge at the time, to connect the island to the mainland. When funds ran dry and construction work stalled, Indianapolis millionaire and recent Miami transplant Fisher intervened, providing the financing needed to complete the Collins Bridge the following year in return for a land swap deal. That transaction kicked off the island's first real estate boom. The Collins Bridge cost over $150,000 and opened on June 12, 1913. Fisher helped by organizing an annual speed boat regatta, and by promoting Miami Beach as an Atlantic City-style playground and winter retreat for the wealthy. By 1915, Lummus, Collins, Pancoast, and Fisher were all living in mansions on the island, three hotels and two bathhouses had been erected, an aquarium built, and an 18-hole golf course landscaped. The Town of Miami Beach was chartered on March 26, 1915; it grew to become a City in 1917. Even after the town was incorporated in 1915 under the name of Miami Beach, many visitors thought of the beach strip as Alton Beach, indicating just how well Fisher had advertised his interests there. The Lummus property was called Ocean Beach, with only the Collins interests previously referred to as Miami Beach. In 1925, the Collins Bridge was replaced by the Venetian Causeway, described as "a series of drawbridges and renamed the Venetian Causeway". Carl Fisher was the main promoter of Miami Beach's development in the 1920s as the site for wealthy industrialists from the north and Midwest to and build their winter homes here. Many other Northerners were targeted to vacation on the island. To accommodate the wealthy tourists, several grand hotels were built, among them: The Flamingo Hotel, The Fleetwood Hotel, The Floridian, The Nautilus, and the Roney Plaza Hotel. In the 1920s, Fisher and others created much of Miami Beach as landfill by dredging Biscayne Bay; this man-made territory includes Star, Palm, and Hibiscus Islands, the Sunset Islands, much of Normandy Isle, and all of the Venetian Islands except Belle Isle. The Miami Beach peninsula became an island in April 1925 when Haulover Cut was opened, connecting the ocean to the bay, north of present-day Bal Harbour. The great 1926 Miami hurricane put an end to this prosperous era of the Florida Boom, but in the 1930s Miami Beach still attracted tourists, and
