Navy Marine Corps Stadium does have two elevators, as well as multiple wheelchair ramps - one ramp located at each corner of the stadium.
Handicap accessible parking is available and can be accessed at northern most portions of the Navy and Gold parking lots (just south of Farragut Road). Handicap parking passes should be obtained in advance, and must be accompanied by a state issued handicapped parking placard or license plate. The closest entry gate to the Navy Lot Handicap parking is Gate G (near the northwest corner of the stadium), while the closest entry to the Gold Lot Handicap parking is Gate J (near the northeast corner of the stadium).
