SR 400 Ramp Closures and Evening Concert Traffic: Atlanta Commute Update for March 4

Commuter Advisory: Major Closures on SR 400

Commuters utilizing State Route 400 should prepare for significant delays today, Wednesday, March 4, as the SR 400 Express Lanes project enters a new phase of active construction. According to the Georgia Department of Transportation (GDOT), the SR 400 Southbound entrance and exit ramps at Holcomb Bridge Road are subject to daily rolling closures from 7:00 a.m. to 5:00 p.m. These closures are necessary for ongoing roadwork and tree clearing within the state right-of-way as crews prepare for heavy construction scheduled for later this spring.

In addition to the daytime ramp work, motorists should be aware of nightly rolling closures between Abernathy Road and SR 141. These single-lane and shoulder closures are scheduled to resume at 9:00 p.m. tonight. Motorists are advised to exercise caution, follow electronic message boards, and reduce speeds when traveling through these active work zones to ensure the safety of roadside crews.

I-285 and I-20 Eastside Construction Update

Work continues on the massive I-285/I-20 East Interchange project in DeKalb County. Crews are currently focused on the new I-20 westbound to I-285 southbound flyover bridge, which is on track for a second-quarter completion. Additionally, the I-20 mainline bridge over Snapfinger Creek is entering its final alignment this week. While no full roadway closures are planned for the peak morning hours, the shifting traffic patterns and narrow lanes near the interchange may cause sudden slowing during the morning and afternoon rush.

MARTA Service and Transit Alerts

Public transit riders should plan for additional travel time due to scheduled station maintenance and long-term detours. MARTA has issued the following alerts for today:

• Escalator and Elevator Maintenance: Ongoing renovations and repairs are affecting access at several key stations, including East Lake, Lenox, Lindbergh Center, and Sandy Springs.
