GDOT’s I-285 and I-20 Interchange Project

Georgia Department of Transportation releases updates on I-285 / I-20.

Georgia Department of Transportation's I-285/I-20 East Interchange project will improve traffic flow and safety at this busy interchange. This critical junction leading to and from Stonecrest requires operational and geometric improvements to address inefficient flow of traffic and safety performance.


Lane Closure Advisory on the I-285/I-20 East Interchange Project

WHAT: Georgia Department of Transportation (GDOT) Contractors will install overnight lane closures on Interstate 20 (I-20) in DeKalb County this weekend to continue a resurfacing project from Columbia Drive to the Rockdale County line. When complete, this resurfacing project will produce a smoother ride for drivers while also improving the condition of the deteriorating roadway. On-site signage will alert drivers approaching the area of the closures in advance. Drivers are advised to plan additional travel time and/or identify alternate routes to avoid the traffic delays related to these closures. For daily traffic impacts and real-time traffic alerts, please visit Georgia NaviGAtor at
