ATLANTA METRO - Crews for Georgia Department of Transportation (GDOT) crews will install lane closures on Interstate 75 (I-75) overpass tunnels in Cobb County and Interstate 20 (I-20) in Fulton County. These closures are a part of a project to upgrade the existing tunnel lighting to energy efficient LED and repair or replace lighting equipment at 14 key locations throughout metro Atlanta, including the ones listed below: the Connector at Capital Avenue/SR 154/Memorial Drive Overpass Tunnel, the Connector at Ralph McGill Boulevard at Baker Street Overpass Tunnel, and I-85 from I-75 to Lenox Road.

Weather permitting, these are the scheduled lane and ramp closures:

9 p.m. on Friday, July 31 until 5 a.m. on Monday

I-75 at Windy Hill Tunnel
  • One right lane, one left lane and the shoulder lanes closed northbound or southbound
5 a.m. on Sunday, August 2 until 5 am. on Monday

I-20 from Linkwood Drive to I-75/I-85 Connector
  • Shoulder lanes closed at each entrance and exit ramp between SR 280/Hamilton E. Holmes Drive (exit 52) and Joseph E. Lowery Boulevard (exit 55A)
GDOT is investing $30 million in 14 projects to replace and upgrade the lighting in the overpass tunnels throughout metro Atlanta.
Motorists are advised to expect delays, exercise caution, and reduce their speed while traveling through the work zone during the project work hours. Before heading out, get real-time information on work status and traffic conditions. Call 511, visit 511ga.org, or download the Georgia 511 app.
