The Georgia Department of Transportation will conduct two public information open houses on Thursday, Feb. 5, on its plan to reconstruct the interchange of Interstate 285 and Georgia State Route 400.

Georgia DOT proposes operational improvements along I-285 and SR 400 near the interchange including:

·         Construction of barrier-separated collector-distributor lanes along I-285 and Georgia 400

·         Reconstruction of existing ramps between the two;

·         Building new flyover bridges and reconstructing and widening existing bridges in the interchange area

·         Construction of grade-separated, braided ramps (where one ramp crosses over another) in the vicinity of Ashford Dunwoody Road and Roswell Road to eliminate conflicts between traffic entering and exiting GA 400 and traffic entering and exiting the Roswell Road and Ashford Dunwoody interchanges.

The Department is seeking public comments on the proposal. The first open house is from 11 a.m. until 1 p.m., and the second from 4 to 8 p.m. the same day. Both will be held atCongregation B’nai Torah, 700 Mount Vernon Highway, NE, Sandy Springs.

Comments will be accepted at the open houses and written statements also can be submitted until Feb. 15 to:
