The Gwinnett County Department of Transportation is adding operational and safety improvements to the T-shaped intersection at West Park Place and Rockbridge Road south of Lilburn near Stone Mountain.

The intersection will go from one to two left-turn lanes from eastbound West Park Place Boulevard onto northbound Rockbridge Road. Dual right-turn lanes will be constructed through the intersection for vehicles going north on Rockbridge Road. A raised median will also be added for about 500 feet on West Park Place Boulevard west of Rockbridge Road to separate traffic going in opposite directions.

Construction will begin later this year with completion in the fall of 2020.

The $2.17 million project is being funded using the 2017 SPLOST program.
