It is eight to 12 lanes wide, with the northern part from I-75 to Georgia 400 to I-85 the most heavily traveled. One segment of the highway near Spaghetti Junction (a large, flyover highway interchange northeast of Atlanta) with Interstate 85 widens to 18 lanes, including collector-distributor lanes. Exits are numbered clockwise, starting at the southwestern-most point at I-85, and ending just east of there where it meets I-85 again near Hartsfield-Jackson Airport.
