Double lane closures are planned nightly from Nov. 27 to Dec. 1 for I-285 eastbound in the top-end Perimeter area of North Fulton and DeKalb counties.

Weather permitting, the two left lanes of I-285 eastbound from west of Glenridge Drive to east of Peachtree Dunwoody Road will be closed from 11 p.m. to 5 a.m. for “geotechnical investigations,” according to the Georgia Department of Transportation.

The work is a part of the Transform 285/400 project, the reconstruction of the I-285/Ga. 400 interchange in the Sandy Springs-Dunwoody-Brookhaven area.
