What’s next: In a few weeks, GDOT will begin construction of I-285 bridges over Glenridge Drive, Ga. 400 and Peachtree Dunwoody Road. That construction will require I-285 to be reduced from five lanes to three in each direction from Roswell Road to Ashford Dunwoody Road. The reduction in lanes will continue through the end of the year. It could be a major traffic headache.
