The projects listed below are just a few of the recently completed projects by the CID.
Pleasant Hill Road Bridge
The Pleasant Hill Road Bridge is a Diverging Diamond Interchange (DDI) that opened over I-85 on June 9, 2013. A DDI is a traffic interchange in which two directions of traffic on the non-freeway road cross to the opposite side on both sides of the bridge, forming a diamond-shaped pattern. The Pleasant Hill Road Bridge at I-85 was the first DDI in Gwinnett County and the second in Georgia.
This innovative traffic design of shifting vehicles to the opposite side of the road proves to be effective in reducing possible points of conflict and eliminating left turns waiting to clear opposing traffic. The traffic flow results, since the Pleasant Hill Road DDI was implemented, show a 51 percent decrease in the average number of stops and a 43 percent decrease in total delay along that portion of Pleasant Hill Road at Club Drive and Satellite Boulevard.
The DDI also allowed for the addition of:
- New traffic signals that align with the new lane configurations and improved signal timing to aide traffic flow
- New sidewalks and streetscapes along the Pleasant Hill Road corridor from Breckinridge Boulevard/Shackelford Road to Venture Drive/Venture Parkway
Pleasant Hill Road at Gwinnett Place Drive/Venture Drive Intersection Improvement Project
In January 2017, construction was completed for a shared right turn lane and through-lane on Gwinnett Place Drive across Pleasant Hill Road along with the addition of a left turn access lane from eastbound Pleasant Hill Road to provide southbound access to Gwinnett Place Drive. Traffic signals and pedestrian facilities at the intersection were also updated as part of the project.

Pleasant Hill Road at Sweetwater Drive Improvement Project
Construction was completed to extend the left turn lane approaching from Sweetwater Road to Pleasant Hill Road in October 2017. This intersection enhancement provides improved vehicular capacity and safety by keeping through-lanes clear of left-turning vehicles waiting for a clear opportunity to turn.
Pleasant Hill Road at Breckinridge Boulevard Intersection Improvement Project
The improvement project for the intersection of Breckinridge Boulevard at Pleasant Hill Road consisted of removing an existing striped island in order to add a second left turn lane, along with approximately 60 feet of an existing center median island planter to lengthen the existing southbound turn lane, turning east onto Pleasant Hill Road.
The construction was due to the partnership of the Gwinnett Place CID with the Gwinnett County DOT (funded through the 2014 Special Purpose Local Option Sales Tax (SPLOST) program).
Old Norcross Road at Breckinridge Boulevard Intersection Improvement Project
In August 2017, Gwinnett County DOT added a second northeast bound left turn lane on Old Norcross Road at Breckinridge Boulevard and improved on pedestrian facilities. Traffic flow was increased with improved vehicular capacity and safety.
