This underground station, opened on January 5, 1918, has two tracks and two side platforms. It is the closest station on the BMT Broadway Line to the former World Trade Center and an exit at the north end once led to the lower concourse. The station sustained significant damage during the collapse of the adjacent World Trade Center towers on September 11, 2001. It was closed for repairs, which included removal of debris, fixing structural damage, and restoring the track beds, which had suffered flood damage in the aftermath of the collapse. The station reopened on September 15, 2002.
The Cortlandt Street BMT station sign is the only one in the NYC system with a bright yellow border.
