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.
