Starting Tuesday, March 5, and going for about three months, controlled blasting for the I-285/Ga. 400 interchange project will affect traffic and MARTA operations in the Dunwoody-Brookhaven area.

The Georgia Department of Transportation announced blasting will occur between 1:30 and 2 p.m. twice a week along eastbound I-285 from the Perimeter Center Parkway overpass to the MARTA bridge, and along westbound I-285 from Perimeter Center to Peachtree Dunwoody Road.

The operation will require traffic pacing on I-285 and Perimeter Center, GDOT said. Blasting will halt traffic on Perimeter Center from Lake Hearn to Hammond drives, and MARTA will provide a flagging operator to coordinate train movements.

Elsewhere in the I-285/Ga. 400 construction zone, GDOT said the ramp from southbound Ga. 400 to westbound I-285 in Sandy Springs will be closed for bridge construction from 9 p.m. to 5 a.m. nightly Monday, March 4 through Friday, March 8.

All work is "weather permitting" and subject to change, GDOT says. Information: https://bit.ly/2jfU8S7
