The left lane of Ga. 400 northbound from Hammond to Spalding drives in Sandy Springs will be closed overnight through Jan. 23 for “pre-construction” work for the makeover of the interchange of Ga. 400 and Interstate 285, state officials say.

Weather permitting, contractors of the Georgia Department of Transportation will close the lane from 8 p.m. to 6 a.m. nightly. Exact dates may change due to weather or other factors. Motorists should reduce their speed, pay attention and watch for workers in work zones, GDOT says.

The $800 million interchange reconstruction, called the Transform 285/400 project, entails new flyover ramps, new collector-distributor lanes and other facilities. It affects 4.3 miles of I-285 from west of Roswell Road to east of Ashford Dunwoody Road, and 6.2 miles of Ga. 400 from the Glenridge Connector to Spalding Drive.

Major construction is to begin by spring and be completed in 2020.
