Before the construction of the bridge, the typical way to cross the Straits of Mackinac was by ferry. By the 1880s, the area had become a popular resort destination, in particular at nearby Mackinac Island. Year-round boat service across the straits had been abandoned as impractical after several attempts. Following the opening of the Brooklyn Bridge in 1883, local residents began to imagine such a structure could span the Straits. (from Wikipedia)
