The projects listed below are just a few of the 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
The CID is not resting on its laurels. While the DDI continues to function effectively, plans must be made for continued improvements to the interchange and surrounding intersections. The CID completed the Pleasant Hill Road at I-85 Interchange Assessment report.
I-85 at Pleasant Hill Road NB Ramp Improvement Project
In partnership with the CID and as a result of CID traffic studies, Gwinnett County DOT directed a project to extend the two lanes at the northbound on-ramp at I-85 and Pleasant Hill Road. The merge point on the on-ramp was pushed further downstream, using existing shoulder space. This initiative gives vehicles more space to merge and reduce the frequency of back-ups extending into the intersection. Construction was completed in August 2019.
Club Drive at Pleasant Hill Road Intersection Improvement Project
The Club Drive intersection improvement project was completed in summer 2018. The project installed northbound triple left lanes on Pleasant Hill Road and eastbound dual right lanes at Club Drive. These added lanes are helping alleviate traffic delays and facilitate better movement through the intersection.
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.
