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 consideration of the COVID-19 pandemic and resulting social distancing measures in place, the project team recently released an updated visualization video that provides an aerial perspective of the I-285/I-20 East Interchange project. The below visualization incorporates changes to the project since the Public Information Open Houses (PIOH) in 2019. To view the current concept design, visit the Document Library.
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. 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
Virtual Information Meeting/Public Hearing Open House
In compliance with social distancing guidelines, and to avoid encouraging the gathering of crowds, Georgia DOT is placing updated project information on an online platform and offering a phone-based, question-and-answer event and physically-distanced, outdoor, in-person Public Hearing Open House (PHOH). The purpose of releasing the updated project information is to allow the public an opportunity to review the proposed project plans and the draft Environmental Assessment (EA), provide feedback, and ask questions about the interchange project. Project materials can be accessed at the following link: https://0013915-gdot.hub.arcgis.com/.
The public is invited to participate in the following ways:
- Review project materials such as the draft EA and conceptual plans and leave comments online at https://0013915-gdot.hub.arcgis.com/.
- Call the project hotline (470) 407-9167 on September 3, 2020, from 5:30 p.m. to 7:30 p.m., to participate in a question-and-answer session with project staff.
- Register to attend a physically-distanced, outdoor, in-person Public Hearing Open House on September 10, 2020, at the Porter Sanford Performing Arts Center, 3181 Rainbow Drive, Decatur, GA 30034. Attendees must register in advance by September 3, 2020, by calling the project hotline (470) 407-9167 and selecting a time slot to attend: 5-6 p.m., 6-7 p.m., or 7-8 p.m.
Comments must be submitted by Thursday, September 24, 2020.
Public Information Open House
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.
