Successful Completion to first Diverging Diamond (DDI) design project in the State of Alabama on SR Highway 181/I-10 in Malbis

The Alabama Department of Transportation and project contractor Arrington Curb and Excavation Inc. recently completed a successful reconfiguration of the I-10/SR-181 interchange into the diverging diamond design, the first DDI in the state of Alabama.

The I-10/SR-181 interchange is heavily traveled year-round by locals and tourists and is surrounded by many businesses, eateries, residencies, and schools. Prior to its reconfiguration,
I-10/SR-181 was a conventional diamond interchange with two lanes of travel in each direction and a heavy volume of signalized left turns onto the interstate against free-flowing traffic. It would often become congested at daily peak travel times and during holidays.
