Dauphin Island Bridge, Road bridge in Mobile County, United States.
The Dauphin Island Bridge extends across the Gulf Intracoastal Waterway with a central span of 400 feet and total length of 17,814 feet.
Hurricane Frederic destroyed the initial 1955 structure in 1979, leading to the construction of the current bridge, which opened in 1982.
The bridge carries the name of Seth Gordon Persons, the 46th governor of Alabama, commemorating his service to the state administration.
The two-lane bridge section of Alabama State Route 193 provides the only direct road access between Mobile County mainland and Dauphin Island.
Engineers used precast concrete segments to construct the bridge, establishing new structural standards for spans of this scale in the region.
