Dunwoody Get Ready for Heavy Traffic at I-285/Ga. 400

From Heneghan’s Dunwoody Blog

Traffic at one of the most congested interchanges in metro Atlanta is about to get dramatically worse as construction peaks at I-285 and Ga. 400.

The weekend after Labor Day, the Georgia Department of Transportation will shrink the Perimeter from five lanes to three lanes in each direction from Roswell Road to Ashford Dunwoody Road, creating a colossal headache for hundreds of thousands of motorists. And it won’t be a short-term hassle.

“This is going to be a long-term, monumental (traffic) shift to get things finished,” GDOT spokesperson Natalie Dale said. “Do you really need to go through this interchange?”

The next phase of construction involves replacing I-285 bridges over Glenridge Drive, Ga. 400 and Peachtree Dunwoody Road. The weekend after Labor Day, GDOT will reduce I-285 from five lanes to three in each direction through the area.

Reducing the number of lanes by 40% will have a dramatic effect on traffic, and GDOT hopes people will avoid the area if they can.

GDOT now says the I-285 lanes will be reduced through June 2022.

PS: what the article doesn’t tell you is that after this phase is completed the bridge over Chamblee Dunwoody will also be replaced which may also reduce 285 lane widths therefore the date of June for a return to normal traffic flow for us may not be accurate.
