Weekend Traffic Outlook: Multiple lane and ramp closures along GA-400 & I-285

It will be a busy weekend along GA-400 and I-285 in Sandy Springs & Dunwoody for the Transform 285/400 project with multiple lanes and ramps closed throughout the weekend. I-285/northbound on the west side of town will also see delays north of I-20. In Cobb County, expect slow zones along I-75 between Marietta and Kennesaw. Also, if Tennessee bound, please note the closure along I-75/nb and I-24/wb near the state line that will last all weekend. WSB will have live traffic updates all weekend to guide you around the delays. As always, please drive safely and remember to use caution in these work zones to keep workers safe.

**All construction is as GDOT reports it and is weather-permitting. All times, lanes blocked, and locations could change.
