Dauphin Island Causeway Shoreline Restoration Update

Activity on the Dauphin Island Causeway Shoreline Restoration Project began last week to maintain the access channels and degrade dredged material berms built last fall, the Mobile County Commission announced. The access channels were created at the beginning of the Dauphin Island Shoreline Restoration Project construction so barges could be brought into position to build the rock breakwaters along approximately 3.5 miles of the Dauphin Island Causeway (State Road 193) between Mobile County’s Bayfront Park and Cedar Point. Access channels from deeper water will continue to be used in later project phases. This work is in preparation for the next phase of the Dauphin Island Causeway Shoreline Restoration Project, during which the U.S. Army Corps of Engineers will place dredged material from the Choctaw Turning Basin behind the recently constructed rock breakwaters to create a marsh platform. This is approved and permitted beneficial use of dredge material, which will restore marshland in Mobile County with sediment from Mobile County. The project is funded by grants from the National Fish and Wildlife Foundation Emergency Coastal Resilience Fund and Gulf Environmental Benefit Fund.
