Gwinnett is adding roundabouts to two intersections in the central and eastern part of the county this summer: Constitution Boulevard at Langley Drive near the Gwinnett Justice and Administration Center in Lawrenceville and the crossroads at Lilburn Stone Mountain Road at Old Tucker Road near Lilburn. Both projects include sidewalks, curbs and gutters, and drainage improvements.

The $1.2 million roundabout in Lawrenceville and the $1 million roundabout in Lilburn are both funded by SPLOST.

Roundabouts allow traffic to flow continuously and reduce the areas of potential conflict between vehicles. As in all crossings, pedestrians should wait for a gap in traffic and cross with care. When entering a roundabout, traffic will be from your left and has the right of way. Do not proceed until there is adequate room for you to safely enter the flow of traffic.
