The U.S. Department of Transportation has approved a $2.52 billion federal loan for Alabama's Interstate 10 Mobile River Bridge and Bayway project, which is part of a larger $4.15 billion infrastructure initiative. This funding will address chronic traffic congestion by constructing a new cable-stayed bridge over the Mobile River that can handle up to 80,000 vehicles daily, compared to the current two-lane tunnel designed for about 35,000 vehicles. The project also includes rerouting hazardous materials away from urban areas through the construction of a direct route across the river for commercial hazmat traffic.

The new cable-stayed bridge will offer six lanes across the Mobile River with a vertical clearance of more than 215 feet, allowing large container ships and oil tankers to pass freely to and from the Port of Mobile.
asserted
ships → stay → Mobile
Along with the river crossing, the project includes replacing and widening the existing low-lying Bayway bridges across Mobile Bay, building a raised structure above 100-year storm surge levels.

project → include → levels
Rerouting hazardous materials away from urban centers
Federal safety rules currently ban vehicles carrying hazardous, flammable, or toxic materials from entering the Wallace Tunnel beneath the Mobile River.
asserted
rules → reroute → River
Because of this, chemical tankers and hazmat trucks must detour through downtown Mobile streets and residential neighborhoods before crossing the river via the Bankhead Tunnel or the Cochrane-Africatown USA Bridge.
asserted
tankers → detour → Tunnel
Official project details released by ALDOT confirm that the new Mobile River Bridge will offer a direct, designated route across the river for commercial hazmat traffic.
asserted
Bridge → release → traffic
Moving heavy hazardous cargo onto the elevated interstate bypass takes dangerous materials off local streets, lowering safety risks for downtown residents and historic business districts.
asserted
Moving → move → residents
The financing secured through the US Department of Transportation operates under the Transportation Infrastructure Finance and Innovation Act (TIFIA), which offers flexible repayment terms backed by future toll revenue.
asserted
which → secure → revenue
