I-10 Mobile River Bridge: Latest Status, Cost, and Timeline for 2026
The I-10 Mobile River Bridge is a major interstate infrastructure megaproject designed to replace aging transit corridors and expand highway capacity between Mobile and Baldwin County, Alabama, making the i-10 mobile river bridge a critical regional priority. Spanning approximately 12 mi, the project overseen by ALDOT addresses major freight bottlenecks along Interstate 10 while preserving maritime commerce access to the Port of Mobile. Developed under a public-private partnership (P3) funding model supported by federal grants, the updated route map and highway alignment will feature a high-clearance cable-stayed bridge and expanded Bayway structure. Thorough environmental review assessments and official plans have guided the ongoing right-of-way process to ensure compliance with federal standards. As engineering work advances toward an estimated completion date in 2029, the project remains essential for enhancing Gulf Coast mobility, driving long-term regional economic growth, and providing reliable hurricane evacuation capacity across Mobile Bay.
