Transportation + Infrastructure Improvements

I-285 at GA 400

The I-285 at GA 400 interchange is undergoing a major upgrade that will add roadway capacity, improve traffic flow, safety and access, and generate opportunity for new investment.

Ashford Dunwoody DDI

The Diverging Diamond Interchange (DDI) design shifts the flow of traffic to the opposite side of the road, reduces points of traffic conflict,  and improves traffic flow and safety.

Flyover Bridge

This 1,100-foot multi-modal bridge has innovative design features such as 4-foot wide bicycle lanes and 6-foot wide pedestrian lanes. HOV access to MARTA is on the horizon.

The half-diamond interchange—named for how it looks from above as it connects the two roads—provides an exit off of Ga. 400 and reduces traffic congestion.
