The Georgia Department of Transportation has announced the latest round of lane closures and other traffic changes for Transform 285/400, its massive project to reconstruct the I-285/Ga. 400 interchange.
The lane closures affect both highways and Mount Vernon Highway, which is a surface street in Sandy Springs. The closures happen only in night and early morning hours: 8 p.m. to 6 a.m.
Among the other traffic changes is “traffic pacing,” or a forced slow-down or stoppage of traffic, on Aug. 6 on a 9-mile stretch of Ga. 400 between central Buckhead and northern Sandy Springs.
Schedules may change based on the work and the weather.
I-285 lane closures
Aug. 4-5: Eastbound and westbound (one right lane and one left lane) between the Lake Forrest Drive underpass and east of Ashford-Dunwoody Road. Hours: 8 p.m. to 6 a.m.
Aug. 9-10: Eastbound (one right lane) between Roswell Road and Glenridge Drive. Hours: 8 p.m. to 6 p.m.
Ga. 400 lane closures
Aug. 4-5: Northbound and southbound (one right lane and one left lane) between the Glenridge Connector and Pitts Road. Hours: 8 p.m. to 6 a.m.
Ga. 400 traffic pacing
Aug. 6: Northbound and southbound, entire highway between Lenox Road and Northridge Road, will have “traffic pacing” –meaning that police cars will force other vehicles to slow or stop — for about 15 minutes between 7 and 10 a.m.
Mount Vernon Highway lane closures
Aug. 7-9: Westbound (one right lane) between Peachtree-Dunwoody Road and Barfield Road. Hours: 8 p.m. to 6 a.m.
Other traffic changes
Ga. 400 flex lanes — where the shoulder of the road is used as an extra travel lane during commuting hours — will be closed intermittently daily between Pitts Road and the North Springs MARTA Station ramp. That is for tree-clearing and utility relocation work. Hours: 7 a.m. to 7 p.m.
I-285 westbound ramp to Ga. 400 will have intermittent “traffic pacing,” meaning that police cars will force other vehicles to temporarily slow or stop. That is for tree-clearing and landscape preparation. Hours: 7 a.m. to 7 p.m.
