The Georgia Department of Transportation released the following updated schedule of lane closures for I-285 and I-20 for the estimated $1.2 billion I-285/I-20 West Interchange project. The primary impacts of this work are on the western portion of the City of Atlanta, and Mableton, Smyrna and the Vinings/Cumberland area in Cobb County.
This week’s updated schedule begins Monday, October 5, and continues through Monday, October 12:
Weather permitting, the Georgia Department of Transportation (Georgia DOT) contractors will temporarily close interstate lanes for the I-285/I-20 West Interchange project. This project will reconstruct and widen several interstate system-to-system ramps at the I-285/I-20 West Interchange and add a combination of collector-distributor lanes or connecting lanes, and auxiliary lanes along I-20 west and I-285 north of the interchange.
