About

Gwinnett County Department of Transportation

Located 30 miles northeast of Atlanta, Gwinnett County has a population of over 900,000 citizens and is one of America's fastest-growing counties in the Metro-Atlanta area. Gwinnett County is one of the most diverse counties in the southeastern United States. Our dynamic and exciting county combines the best of big-city living with the comforts of the suburbs.

An intricate part of Gwinnett County is the Department of Transportation, which is responsible for overseeing the roadway infrastructure system. Gwinnett County' Department of Transportation's mission is to enhance quality of life by facilitating the mobility of people and goods safely and efficiently. This mission is accomplished by planning, constructing, operating, and maintaining the aviation, transit and surface transportation systems.

Gwinnett County's The Department of Transportation consists of three groups: Intermodal Operations, Capital Program Delivery and Traffic Engineering, Operations and Maintenance. The Department maintains an infrastructure system that includes more than 2,500 miles of road, over 700 signalized intersections, thousands of miles of traffic striping, the Gwinnett County Transit System and one of the four busiest airports in Georgia. The Department performs this mission with 155 approved full-time positions and a 2018 adopted operating budget of $44.5 million in multiple funds.

Traffic Engineering oversights include:

  • Ensuring a safe and efficient transportation system by maintaining the countywide traffic signal system
  • Monitoring existing travel conditions
  • Maintaining traffic volume and traffic accident data bases and providing analyses, reports and recommendations for corrective measures
  • Developing and managing the residential speed control and street light programs
  • Maintains over 200 flashers, over 225 miles of fiber optic communications cable and more than 250 CCTV cameras 
  • Traffic Control Center and the GC Smart Commute website.

Special Projects: 

Peachtree Industrial Blvd Smart Corridor

One example of how Gwinnett is seeking to pioneer new transportation solutions is the Peachtree Industrial Blvd. Smart Corridor.  This project will install technology that will enable traffic signals to communicate with drivers via a smart phone app or potentially directly to the vehicle. It could tell you how long until a signal changes, when you’re in a work zone, a school zone or which direction an emergency vehicle is approaching from. Transit buses and emergency vehicles will have the ability to change signals, ensuring buses stay on schedule and first responders arrive at the scene of an emergency safer and faster. The project will add this connected/autonomous vehicle technology to PIB from Peachtree Corners to Hall County and will begin installation in 2019. It will help reduce the number of crashes and enhance the flow of traffic.

Diverging Diamond Interchange

The Diverging Diamond Interchange's (DDI) innovative design relieves congestion, improves safety, and is less expensive than replacing or widening the bridge. A DDI shifts traffic to the opposite side of the road, making left turns onto the interstate easier and improving the flow of traffic across the bridge.
