The original Cortlandt Street station was built by the Interborough Rapid Transit Company (IRT) and opened in 1918 as part of the Dual Contracts. The station was renovated in the 1960s when the original World Trade Center was built. Around that time, the portion of Cortlandt Street above the station was demolished to make way for the World Trade Center. The Cortlandt Street station was destroyed on September 11, 2001. Although service on the Broadway–Seventh Avenue Line through the area was restored in 2002, the station's reconstruction was delayed until 2015 because the Port Authority of New York and New Jersey had to first rebuild the World Trade Center PATH station beneath it. After an extensive reconstruction, the Cortlandt Street station reopened on September 8, 2018, as WTC Cortlandt.
