The weekly Gwinnett road closure report from the Gwinnett Department of Transportation for March 2-8 plus advisory about lane closings on I-85 and Pleasant Hill Road due to Diverging Diamond Interchange construction:

"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. PleasantHill Road lane closures will take place between 9 a.m. and 4 p.m. and between 9 p.m. and 6 a.m.

"Gwinnett County is continuing the construction of converting the existing Pleasant Hill Road bridge over I-85 into a Diverging Diamond Interchange, or DDI. The DDI’s innovative design relieves congestion, improves safety and is less expensive than replacing the bridge. 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."
