If you are driving to the Georgia Tech campus, the most convenient visitor parking is located at the North Campus Parking Deck (W23/Visitor Area 5) at 911 State Street NW, Atlanta, GA 30318. 

The entrance to the deck is on State Street. After parking, exit the deck on the side facing Atlantic Drive NW (opposite of State Street). From there, walk up the hill to your RIGHT—the Marcus Nanotechnology Building will be just ahead.
