DDI Construction Requiring Traffic Adjustments

Gwinnett County is continuing to convert the existing Pleasant Hill Road bridge over I-85 into a Diverging Diamond Interchange, or DDI. The construction is requiring traffic adjustments.

Intermittent lane closures and up to three lanes of traffic shifts will take place on I-85 at Pleasant Hill Road from March 1 to approximately March 22, weather permitting.

Pleasant Hill Road from Breckinridge Boulevard/Shackleford Road to Venture Parkway will continue to require intermittent lane closures and traffic shifts through September 2013.

Lane closures on I-85 will take place from 8 p.m. to 5 a.m. Sunday through Thursday, 8 p.m. Friday to 7 a.m. Saturday and 8 p.m. Saturday to 9 a.m. Sunday. Pleasant Hill Road lane closures will take place between 9 a.m. and 4 p.m. and between 9 p.m. and 6 a.m. 

A DDI shifts traffic to the opposite side of the road, making left turns onto the interstate easier and improving the flow of traffic across the bridge.

The DDI is being built to relieve congestion and improve safety. Also, it is less expensive than replacing the bridge.
