Dauphin Island Bridge, Road bridge in Mobile County, United States.
The Dauphin Island Bridge, formally the Gordon Persons Bridge, carries a two-lane section of Alabama State Route 193 across the Gulf Intracoastal Waterway at Pass Aux Herons. Its long, low flat span rests on closely spaced vertical piers, while the left end rises into a single tall arched section with a curved underside. The bridge separates the Mississippi Sound on the west from Mobile Bay on the east.
The original bridge was built in 1955 but was destroyed by Hurricane Frederic in 1979. The current structure was completed in 1982 as its replacement.
The bridge is named after Seth Gordon Persons, the 46th governor of Alabama, honoring his contributions to state government. Many travelers crossing it are unaware of this naming tribute.
The bridge forms part of Alabama State Route 193 and accommodates standard vehicle traffic. Visitors should be aware that this is the sole road access to the island, particularly important to consider during uncertain weather or planned maintenance work.
The 1982 replacement bridge's central main span was the first use of a 400-foot (122 m) span on a precast concrete segmental bridge. The structure carries Alabama State Route 193 over Pass Aux Herons, the natural channel of the Gulf Intracoastal Waterway.
