Contractors are working on the new SR 324/Gravel Springs Road interchange on Interstate 85. The Gwinnett Board of Commissioners in mid-2019 approved a construction agreement with the Georgia Department of Transportation to fund the construction of the new interchange. Commissioners awarded the construction contract to E.R. Snell Contractor, Inc.

This project will construct a new interchange around the existing bridge at SR 324/Gravel Springs Road at I-85. The project includes four new ramps from Gravel Springs Road, with turn lanes and traffic signals, sidewalks, sound barriers and retaining walls.

This project has $20,000,000 in federal funds to cover the construction contract amount of $19,000,000 in addition to construction engineering, inspection, and testing costs.

The County funded engineering costs through the 2014 Special Purpose Local Option Sales Tax (SPLOST). Right of way was purchased with federal and state funds.

Weather permitting, construction is to forecast for completion in mid-2022. View the project layout (PDF).
