Tremont Avenue is an express station on the New York City Subway's IND Concourse Line. Prior to a 1999 renovation, the station had a full length mezzanine connecting both the ends of the station. The full time booth is on the south side at Tremont Avenue with three street stairs and two stairs to each platform. The street stair on the west side has a small passageway. The part time side at the north end has a former booth that was removed during the renovation and two street stairs (one to each side of the Concourse at 179th Street) and two stairs to each platform. There is also one staircase at the center of each platform. They only lead to a storage area, but the passageway can be seen from platform level. The tile band and name mosaics are replicas of original purple band. A closed towe
