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 closures will happen in night and early-morning hours. Schedules may change based on the work and the weather.

Other traffic changes

On Nov. 4, I-285 westbound between Ashford-Dunwoody Road and Peachtree-Dunwoody Road will have one right lane traffic-paced — meaning that police cars will force other vehicles to temporarily slow or stop. Hours: 7 a.m. to 8 p.m.

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.
