The Georgia Department of Transportation's Transform 285/400 improvement project is designed to help reduce traffic congestion and enhance safety in the area near the I-285/SR 400 interchange in metro Atlanta. This priority project adds new flyover ramps, new collector-distributor lanes and other facilities to aid east-west travel along I-285 and north-south travel along SR 400.

The project will improve 4.3 miles of I-285 from west of Roswell Road to east of Ashford Dunwoody Road and 6.2 miles along SR 400 from the Glenridge Connector to Spalding Drive.

Intermittent Flexible Shoulder Lane Closures Planned: 

Crews will implement daily closures on northbound and southbound SR 400 flexible shoulder lanes between the MARTA North Springs station ramp and Pitts Road, daily between 7 a.m. and 7 p.m.

Lanes will be closed intermittently to facilitate construction of the Transform 285/400 improvement project. Near-term closures will facilitate tree clearing efforts and utility relocations in preparation for interchange reconstruction.
