Cortlandt Street (also known as Cortlandt Street–World Trade Center) was a station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. The station and the surrounding subway tunnels were severely damaged in the September 11, 2001 attacks, and the line south of Chambers Street was temporarily closed. The steel I-beams of the station were crumpled. What was left of the station was completely demolished, and walls were constructed where the platforms used to be. This portion of the line was entirely rebuilt, and reopened on September 15, 2002, with trains traveling directly between Chambers Street and Rector Street.
The station was named after Cortlandt Street, which formerly ran east west from Broadway to West Street in Lower Manhattan, nicknamed "Radio Row" because of the many electronics dealers on the street. In 1965, Cortlandt Street west of Church Street was demolished to create the superblock of the World Trade Center. The station, with entrances at Vesey Street and inside the World Trade Center concourse, was not particularly close to the remaining block of Cortlandt Street. The station is expected to be reopened as part of the World Trade Center site reconstruction.
