- I-10 Mobile River Bridge, EIS, Mobile and Baldwin Counties, Alabama
Alabama Department of Transportation
Environmental lead and principal author on this $850 million project to provide additional vehicle capacity across the Mobile River in the vicinity of the existing I-10 Wallace Tunnels and to widen the elevated bridges across Mobile Bay. Alternatives were evaluated ranging from multiple new location crossings of the Mobile River and Mobile Bay to design alternatives including tunnels, movable bridges and high air draft clearance, fixed bridges. Through an extensive coordination effort and detailed evaluation of potential maritime economic impacts, the DEIS carried forward four alternatives involving cable-stayed bridges with 215 feet of air draft clearance. Environmental concerns ranged from protected species issues to detailed coordination with resource agencies, Consulting Parties and the Advisory Council on Historic Preservation on view shed impacts to historic properties. The DEIS was reviewed at FHWA Headquarters for legal sufficiency and Section 106 compliance. The DEIS was approved in 2014. Project information is located at www.mobileriverbridge.com.
