I-285/I-20 East Interchange
The I-285/I-20 East Interchange project will improve traffic flow and safety at this busy interchange. This critical junction in DeKalb County requires operational and geometric improvements to address inefficient flow of traffic and safety performance. The project consists of:
- Reconstructing ramps
- Constructing new collector-distributor (CD) lanes
- Adding auxiliary lanes along I-20 and I-285
- Replacing the Miller Road, I-20 over Snapfinger Creek, and Fairington Road bridges and I-285 northbound over Snapfinger Road
In November 2019, the Georgia DOT presented a design concept of the proposed I-285/I-20 East Interchange Project at two (2) Public Information Open Houses (PIOHs). The PIOHs were hosted to offer attendees the opportunity to view the project displays, submit valuable public comments and ask questions of the project team. Information presented to the public at the PIOHs can be accessed by clicking here. Over 237 people attended and submitted 91 total comments. An official PIOH Comment Response document was developed to address the comments and can be found here.
Additional Project Information
- Constructing new I-20 westbound to I-285 southbound and I-285 southbound to I-20 eastbound ramps
- Widening the I-20 eastbound to I-285 northbound ramp from one to two lanes
- Constructing westbound collector-distributor (CD) lanes between Wesley Chapel Road and the I-285/I-20 East Interchange
- Constructing one westbound auxiliary lane between Lithonia Industrial Boulevard and Wesley Chapel Road
- Constructing one eastbound auxiliary lane from Panola Road to Lithonia Industrial Boulevard
- Extending auxiliary lanes on I-285 northbound
- Extending one auxiliary lane on the I-20 eastbound CD lanes to the Wesley Chapel Road off-ramp
- Constructing replacement bridges along I-20 to accommodate the new auxiliary and CD lanes
*Collector-distributor (CD) lanes run parallel to the main travel lanes of an interstate or highway, connecting them to access roads or entrance ramps in order to improve traffic flow, speed, and safety.
Project Public Participation
A series of Public Information Open Houses (PIOHs) were held in November 2019. The purpose of the meetings was to provide opportunities for the public to view current plans, ask questions, and provide feedback. More than 230 people attended. View the materials displayed at the PIOHs from the Document Library.
Noise barriers will be evaluated as part of this project in accordance with the Georgia DOT noise policy and Federal Highway Administration noise regulations. As the environmental field work and roadway design moves forward, property owners and renters who are eligible for a proposed noise barrier will be notified of the opportunity to participate in noise barrier voting.
