DDI construction impacts I-85

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 8:00pm to 5:00am Sunday through Thursday, 8:00pm Friday to 7:00am Saturday, and 8:00pm Saturday to 9:00am Sunday. Pleasant Hill Road closures will take place between 9:00am and 4:00pm and 9:00pm and 6:00am. 

Gwinnett County is continuing the construction of converting the existing the 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 or widening 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. Find out more about how to drive the diamond at
