I-285/I-20 East Interchange
The I-285/I-20 East Interchange project will improve traffic flow and safety at this heavily travelled junction in DeKalb County. The project consists of:
• Reconstructing I-285/I-20 East Interchange ramps with more direct alignments and additional lanes where warranted
• Constructing new collector-distributor (CD) road along westbound I-20 and an additional lane in the eastbound I-20 CD road between the I-285/I-20 East Interchange and Wesley Chapel Road
• Adding auxiliary lanes along I-20 and I-285
• Replacing the Miller Road bridge over I-20, and the I-20 bridges over Snapfinger Creek, and Fairington Road
• Widening the I-285 northbound bridge over Snapfinger Road
• Constructing new noise barriers where feasible and reasonable per the preliminary noise impact assessment
The project team released an updated visualization video in September 2020 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.
Additional Project Information
• Construction of new I-20 westbound (WB) to I-285 southbound (SB), I-20 WB to I-285 northbound (NB), and I-285 SB to I-20 eastbound (EB) ramps
• Widening of the I-20 EB to I-285 NB ramp from one to two lanes
• Construction of I-20 WB CD lanes between Wesley Chapel Road and the I-285/I-20 East Interchange
• Construction of one I-20 WB auxiliary lane between Lithonia Industrial Boulevard and Wesley Chapel Road
• Construction of one I-20 EB auxiliary lane from Panola Road to Lithonia Industrial Boulevard
• Extension of auxiliary lanes on I-285 NB to Glenwood Road north of the I-285/I-20 East Interchange
• Extension of one auxiliary lane in the I-20 EB CD Road from the I-285/I-20 East Interchange to the Wesley Chapel Road Interchange off-ramp
• Construction of replacement bridges along I-20 to accommodate the new auxiliary and CD lanes
• Realignment of Fairington Road to be contiguous with DeKalb Medical Parkway
• Construction of new noise barriers where feasible and reasonable per the preliminary noise impact assessment
*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. Auxiliary lanes are the extra lanes alongside the main lanes that give drivers more time to merge in or out when entering or exiting the highway.
Project Public Participation
Virtual Information Meeting/Public Hearing Open House
Following the Federal Highway Administration’s approval of the project’s Draft Environmental Assessment (EA) and in consideration of the COVID-19 pandemic and the resulting social distancing measures in place, Georgia DOT hosted several public outreach events in August and September 2020 to inform the public of the project status and to allow for public comments on the project. Through a combination of a Virtual Information Meeting, Call-in Question and Answer Session, and an outdoor, physically distanced in-person Public Hearing Open House (PHOH), approximately 320 people were engaged.
These events have enabled Georgia DOT to move the I-285/I-20 East Interchange Project forward in a responsible manner that meets requirements for public outreach on federally funded projects. Comments that were received from these events during the public comment period which ended on September 24, 2020 have been collected and responses published in an official PHOH Comment Response document that has been posted in the Document Library.

Public Information Open House
Two Public Information Open Houses (PIOHs) were held in November 2019. The purpose of the PIOHs was to provide opportunities for the public to view current plans, ask questions, and provide feedback. More than 230 people attended and submitted 91 total comments. View the materials displayed at the PIOHs and the public comment response letter in the
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.
