The I-10 Wallace Tunnels in Mobile top the list of Alabama’s worst transportation chokepoints, along with multiple sections of I-65, I-20 and I-85.

This is according to a new report released Oct. 28 by TRIP, a Washington, D.C.-based national transportation research organization.

TRIP’s report, “Alabama’s Transportation Chokepoints: The Top 40 Chokepoints and Remedies for Relief,” ranks the state’s urban interchanges, highway segments, transit routes, and sections of rural highways that provide inadequate mobility.

These transportation chokepoints impede local, regional or interstate travel, diminish the quality of life of residents and visitors, reduce economic competitiveness, and stifle economic growth and recovery by hampering commuting, commerce and other travel.

In addition to identifying the chokepoints, the report also offers potential improvements for each segment that would ease the burden on travelers and allow for improved mobility.

According to the TRIP report, the worst transportation chokepoint in Alabama is the I-10 Wallace Tunnels under the Mobile River in Mobile County.

The state’s most severe chokepoints also include the following: I-65 from I-20 to US 31 in Jefferson County, US 280 from Brook Highland Parkway to Riverview Road in Jefferson County, I-65 from SR 119 to I-459 in Jefferson and Shelby Counties, US 280 from Cahaba River Road/Dolly Ridge Road to Cherokee Drive in Jefferson County, I-65 from Airport Boulevard to Springhill Avenue in Mobile County, I-65 from County Road 52 to State Road 119 in Shelby County, I-20 from Airport Highway to US 31 in Jefferson County, Birmingham’s regional transit system, and I-85 from I-65 to Taylor Road in Montgomery County.

The report’s appendix contains a full list of the 40 worst chokepoints in the state as well as possible solutions to ease each chokepoint.
