The city's contractors have finished the paving project on Winters Chapel Road and have now moved on to Mt. Vernon Road.
Duwnoody motorists can try to avoid Mt. Vernon Road west of Ashford Dunwoody, where construction is going on.
The Mt. Vernon Road closure is designed to avoid peak traffic times. The road is expected to open back up by 4 p.m. Thursday. It will be closed again from 9 a.m. to 4 p.m., according to the city's estimates.
