Big changes coming for Mount Vernon Highway, GDOT says

Motorists who use Mount Vernon Highway in Sandy Spring and Dunwoody can expect big changes before year’s end around its bridge over Ga. 400, the Georgia Department of Transportation says.

Crews are laying pipe next to and across Mount Vernon, according to GDOT's latest online newsletter on the I-285/Ga. 400 interchange reconstruction in North Fulton and DeKalb counties. "This work requires a daytime continuous closure, nightly lane closures and some weekend lane closures," GDOT says.

It’s all preliminary to switching traffic to the new bridge at Ga. 400 so crews can begin demolishing the old bridge. The work affects Mount Vernon between Barfield Road and Crestline Parkway

Meanwhile, along Abernathy Road, crews are relocating a gas line to prepare for a new diverging diamond interchange at Ga. 400. Crews will be working in the area until the end of the year. During that time, the sidewalk on Abernathy in front of the Mercedes-Benz headquarters will remain closed to pedestrians and bicyclists.
