The Jimmy Carter bridge is the heart of the Gwinnett Village Community Improvement District. It is also one of the busiest interchanges along the entire I-85 corridor. When the CID was founded in 2006 it became evident immediately that something was going to have to be done to relieve congestion at this vital access point to our community.

Given the fact that transportation resources are stretched thin already, the CID new that we would have to find an innovative way to relieve congestion for the lowest possible cost.

Design Details

The CID immediately gravitated toward an innovative design known as a Diverging Diamond Interchange (DDI). The design, which originated in France, has begun to see more and more popularity among transportation circles because of its effectiveness in relieving congestion at interchanges while being relatively inexpensive to construct (due to the fact that you can utilize the existing bridge).

Beyond congestion relief the CID saw an opportunity to turn this piece of infrastructure into a defining, memorable piece of architecture that could enhance the character of the entire community. The CID contracted Peter Drey (designer of the 14th Street bridge in Atlanta) to work with CID staff and a group of community stakeholders to come up with a design that was representative of where the community is now and where we envision it in 10-15 years.

The CID is working in partnership with the Gwinnett County Department of Transportation to turn this innovative design into a reality. Gwinnett County is currently working on two DDIs (the one at Jimmy Carter and another at Pleasant Hill Road and I-85). If you’d like to find out more information on these please visit www.gwinnettddi.com.

Construction of the project is underway and the Gwinnett Village CID is working closely with Gwinnett County to complete the project in Spring, 2014.

Current Construction Updates:

• Contractors have begun grading the four quadrant around the bridge to make room for the road reconfiguration
• The sidewalk has been closed on the south side of the bridge while work begins on the bridge facade.
• There will be intermittent lane closure (primarily overnight) while work is done on the actual bridge and roadway.
