I-285/I-20 East Interchange P3, Georgia

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 includes ramp reconstruction, construction of collector-distributor lanes between Wesley Chapel and I-285 interchange, and a west-bound auxiliary lane between Lithonia Industrial Boulevard and Panola road. The project results in 18 additional lane miles and consists of: Construct new I-20 westbound (WB) to I-285 southbound (SB), I-20 westbound to I-285 northbound (NB) and I-285 SB to I-20 eastbound (EB) ramps Widen the I-20 EB to I-285 northbound ramp from one to two lanes Construct WB collector-distributor (CD) lanes* between Wesley Chapel Road and I-285/I-20 East Interchange Construct one WB auxiliary lane between Lithonia Industrial Boulevard and Wesley Chapel Road Construct one EB auxiliary lane from Panola Road to Lithonia Industrial Boulevard Extend auxiliary lanes on I-285 NB Extend one auxiliary lane in the I-20 EB CD lanes to the Wesley Chapel Road off-ramp Replace the Miller Road and Fairington Road bridges over I-20, and the I-20 bridge over Snapfinger Creek to accommodate the new auxiliary and CD lanes Replace the Miller Road and Fairington Road bridges over I-20, and the I-20 bridge over Snapfinger Creek to accommodate the new auxiliary and CD lanes This project is part of Georgia's Major Mobility Investment Program (MMIP): The Georgia Department of Transportation (Georgia DOT) is making major investments in the state’s transportation network to deliver projects that will meet a community need and deliver positive benefits to drivers.
