USDOT announced a TIFIA loan of up to $2.52 billion for Alabama's I-10 Mobile River Bridge and Bayway project, including a six-lane bridge, added Bayway capacity and a direct interstate route for hazmat trucks.
USDOT announced the financing on September 18
The U.S. Department of Transportation said on September 18, 2026 that the Alabama Toll Road, Bridge, and Tunnel Authority will receive a Transportation Infrastructure Finance and Innovation Act loan of up to $2.52 billion. The Build America Bureau loan is intended to help fund construction of the Mobile River Bridge and Bayway Project on Interstate 10.
The loan is federal financing, not a $2.52 billion grant
TIFIA provides long-term federal credit assistance to eligible transportation projects. USDOT described this action as a loan of up to $2.52 billion, not a direct grant for that amount and not the project's complete price tag. The Alabama authority is the borrower, while the Alabama Department of Transportation will construct and manage the project.
A new six-lane bridge will cross the Mobile River
The federal announcement says the project includes a new six-lane, cable-stayed bridge over the Mobile River. It is designed to address congestion around the George Wallace Tunnel and the I-10 corridor through Mobile. The release says the completed improvements could reduce travel times by up to 30 minutes; it does not promise that reduction on every trip or during construction.
The Bayway will gain capacity
The project will reconstruct approximately one mile of the existing Bayway and restripe the full 7.5-mile Bayway from two to three lanes in each direction. It also includes interchange, intersection and traffic-flow improvements in Mobile and Baldwin counties. Those elements are intended to support the new bridge, expanded Bayway capacity and hurricane evacuation.
Freight access to the Port of Mobile is an explicit project goal
USDOT identified improved freight access to the Port of Mobile as one of the project's expected benefits. The I-10 corridor connects Gulf Coast freight movements with port, industrial and regional destinations. Added capacity can matter to carriers, but the announcement does not set a construction-phase truck route, delivery window or guaranteed port travel time.
Hazmat trucks are a central operating issue
The federal release says hazardous materials are prohibited from using the George Wallace Tunnel, forcing hundreds of trucks each day to detour through downtown Mobile and nearby neighborhoods. USDOT says the project will provide those vehicles with a direct interstate route. Until that route is open and officially authorized, drivers must continue to follow current tunnel restrictions, signs and approved hazmat routing.
The loan builds on a separate $550 million bridge grant
USDOT noted that FHWA announced a $550 million Bridge Investment Program grant for the same corridor in May 2025. The grant and the newly announced TIFIA loan are different financing tools. Adding the headline figures without accounting for project finance structure, eligible costs and loan repayment would not produce a reliable estimate of total project funding or cost.
Construction will require current route checks
Major bridge, Bayway and interchange work can change lane configurations, shoulders, work-zone speeds, ramp access and oversize or hazmat routing. Dispatchers and drivers should consult current ALDOT notices, official 511 information, permit instructions and roadside signs before each movement. A federal financing announcement is not an operational route bulletin.
Hazmat compliance remains unchanged
The loan does not waive hazardous-material endorsements, shipping papers, placarding, security-plan duties, route restrictions or vehicle requirements. It also does not alter hours-of-service, CDL, medical, size-and-weight or out-of-service rules. A future direct interstate path becomes usable only under the rules and official opening conditions in effect at that time.
Carriers should separate long-term planning from today's dispatch
Long-term network planning can consider the project's stated freight and port benefits. Daily dispatch should still price current detours, congestion, tolls, construction delay, fuel, legal parking and appointment risk. Contracts should identify which party absorbs route changes and tolls rather than assuming the announced loan immediately changes lane economics.
No completion date was stated in the USDOT release
The September 18 federal announcement describes project elements, financing and expected benefits, but it does not state a construction completion date. CDL Truck Pro has not inferred one. Drivers and fleets should use later project documents and official construction updates for start dates, phasing, openings and restrictions.
What the announcement means for truck operators
The concrete news is that USDOT announced up to $2.52 billion in TIFIA financing for a defined I-10 bridge and Bayway project with freight, hazmat and port-access components. It does not mean the new route is open, the tunnel restriction has ended or every I-10 shipment will save 30 minutes. Those distinctions matter for safe routing and accurate customer expectations.
