Dauphin Island Bridge

The Dauphin Island Bridge is a two-lane road crossing that spans the Gulf Intracoastal Waterway in Mobile County. It serves as the only direct road link connecting the mainland with Dauphin Island, making it essential for traffic between these two areas.

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 construction employed precast concrete segments, a method that set new building standards for bridges of this scale in the region. This technique allowed for faster and more efficient assembly.
