This week marks the 50th anniversary of the opening of Interstate 285, well-known across metro Atlanta as "The Perimeter."

The Georgia Department of Transportation worked with the Atlanta History Center to compile these old photographs — which come from the history center's collection — to illustrate I-285's early history, from the 64-mile perimeter's opening to the opening of Spaghetti Junction.

GDOT officials announced an exhibit about the history and use of I-285 will be on display through Saturday in a pop-up exhibit near Dillard's on the lower level of Perimeter Mall, which is located at 4400 Ashford Dunwoody Road in Dunwoody.

The exhibit will include historical photographs, a demonstration about mobility on the interstate has evolved and a reproduction of I-285 that was built by LEGOLAND Discovery Center Atlanta and HNTB.
