Major Lane Closures on GA 400 Expected to Impact North Fulton Commutes Today

Georgia 400 Express Lane Project Triggers Major Closures

Commuters in North Fulton and Forsyth counties should prepare for significant disruptions as heavy construction begins on the $4.6 billion Georgia 400 express lanes project. The Georgia Department of Transportation (GDOT) has confirmed that rolling lane closures and shoulder work will be in effect throughout the day on Tuesday, March 10, 2026. These disruptions are part of a massive five-year project aimed at adding two express lanes in each direction from the North Springs MARTA Station to McFarland Parkway.

Key closures impacting the Tuesday morning and afternoon commutes include:

• Northridge Road: Daily rolling closures on the SR 400 NB exit ramp (right lane) and the entrance ramp (left lane) from 7:00 a.m. to 5:00 p.m.
• Mansell Road: Bus lane and shoulder closures on the SR 400 NB entrance ramp through the early morning hours.
• Webb Bridge Road: Nightly single lane closures at the SR 400 overpass starting at 9:00 p.m. tonight.
• Old Dogwood Road: A right turn lane closure at Holcomb Bridge Road is scheduled to begin at 9:00 p.m.

MARTA Transit Updates and Service Changes

MARTA riders should note several service adjustments today. As the transit agency prepares for the full rollout of the NextGen Bus Network next month, ambassadors are currently stationed at major hubs like Lindbergh Center and Kensington to assist with trip planning. The newly launched MARTA Reach on-demand service is now available in 12 regional zones to provide connectivity in areas with modified bus routes.

• Rail Service: Red Line trains are operating between North Springs and Lindbergh Center. Passengers heading further south must transfer at Lindbergh Center.
• Station Alerts: Escalator repairs are ongoing at Lenox Station, though most are expected to return to service by mid-morning.
• Fare Modernization: Installation of new "Better Breeze" tap-to-pay gates continues at Doraville and East Point stations; please allow extra time for navigating these work zones.

Arterial Incidents and Roadworks

Beyond the major work on GA 400, several other incidents are slowing traffic across the metro area this morning:

• I-75/85 (Downtown Connector): Expect delays northbound near Edgewood Avenue due to emergency pothole repairs blocking two center lanes.
• I-85 Southbound: A center lane remains blocked near Collinsworth Road for ongoing roadway maintenance.
• I-20 Eastbound: A crash near McDaniel Street is causing localized tailbacks in the right lane.

Commuters are advised to utilize navigation apps to monitor real-time speeds and consider taking MARTA to avoid the heaviest congestion points in the North Fulton corridor. GDOT encourages all drivers to reduce speeds and remain alert when traveling through active work zones.
