The Georgia Department of Transportation has announced the latest round of lane and ramp closures and other traffic changes for Transform 285/400, its massive project to reconstruct the I-285/Ga. 400 interchange.
The main lane and road closures will happen in night and early-morning hours. Schedules may change based on the work and the weather.
I-285 lane closures
Sept. 29-30: Eastbound and westbound between Lake Forrest Drive underpass and east of Ashford-Dunwoody Road, one right lane and one left lane. Hours: 8 p.m. to 6 a.m.
Ga. 400 lane closures
Sept. 29-30: Northbound and southbound between Glenridge Connector and Pitts Road, one right lane and one left lane. Hours: 8 p.m. to 6 a.m.
Ga. 400 ramp closures
Oct. 2-5: Soutbound ramp to I-285 eastbound closed; traffic to detour onto Glenridge Connector. Hours: 9 p.m. to 5 a.m.
Other traffic changes
I-285 eastbound and westbound ramps 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.
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.
