I-285 / I-20 East Interchange – DeKalb County, GA

GDOT’s primary objective for this project is improving traffic flow within the I-285/I-20 East Interchange and along portions of I-20 east of the I-285/I-20 East Interchange, one of the most heavily traveled areas in the Atlanta region. This project consists of the following:

• Reconstructing I-285/I-20 East Interchange ramps with more direct alignments and additional lanes
• Constructing new collector-distributor (CD) road along westbound I-20
• Constructing 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 and Fairington Road bridges over I-20, and the I-20 bridge over Snapfinger Creek
• Widening the I-285 northbound bridge over Snapfinger Road
• Constructing new noise barriers

For this project ICE serves as the Lead Design Consultant, performing overall design management along with roadway, drainage, and structures design for the main interchange and mainline work west of Wesley Chapel Road, as well as geotechnical engineering services for the entire project. ICE was responsible for the completion of design and engineering drawings and the coordination of the design team, including major and minor subconsultants. ICE was responsible for the supervision and quality of all design work and design processes throughout the term and ensured accuracy, adequacy, and conformance of the work to the technical provisions, professional standards of practice, and other applicable standards, specifications, and criteria, including conformance of the constructed project to the design. Currently, ICE is providing construction support services through Final Acceptance.
