Eastern Shore Diverging Diamond Project

Find updates to the Eastern Shore Diverging Diamond Interchange project here.


Weather permitting, the Alabama Department of Transportation (ALDOT) is closing the Interstate 10 and State Route 181 interchange on Sunday, June 28, beginning at 9 p.m. in order to prepare it for shifting traffic into the new diverging diamond configuration.

The scope of work for the interchange closure includes, closing the SR-181 north and southbound lanes between Eastern Shore Blvd. and Demetrios Blvd. as well as the I-10 entrance and exit ramps beginning at 9 p.m. Sunday night. Motorists will not be able to exit or enter I-10 at SR-181 nor will they be able to cross the I-10 overpass on SR-181.

The contractor crews will work 24 hours daily to perform striping and lane reconfigurations, barrier rail and guardrail installations, signage installation and modifications, and signalization of the interchange during this time in order to minimize the time of closure. Motorists will be detoured at Exit 35 where they can use US-90 and US-31 to access SR-181 and I-10.

Traffic enforcement officers will be present during this time period to assist in these closure operations. This will also include tow trucks and first responders, whom will be positioned within close proximity to I-10 during the closure to quickly assist with any traffic accidents which could cause additional delays or congestion near the interchange. Business accesses will remain open north and south of the interchange along SR 181.

The interchange will be open with traffic shifted into the new diverging diamond traffic configuration by Wednesday, July 1, at 5 a.m.

In the following weeks after the traffic shift, motorists can expect alternating lane closures throughout the work zone as the contractor places concrete islands, the final asphalt layer and permanent striping, and completes the installation of permanent signals before the project is accepted as complete.

There will be alternating southbound lane closures on SR-181 today from 9am - 4pm between US-90 and the Eastern Shore Center as the contractor performs asphalt operations. Additional signage will be implemented in the work zone. Consider using US-31, US-98, US-90 as an alternate route.

As you approach the traffic signals at each end of the I-10/SR-181 interchange, you will notice the north and southbound SR-181 lanes are now at a new angle in preparation for the traffic shift into the new diverging diamond configuration. While the shift is still a few weeks away, please use caution and pay attention to all signage and traffic control items (barrels, cones, etc) as you adjust to this new angle.
