It took almost 17 years, but the MTA is finally reopening the Cortlandt Street subway station that’s been shuttered since 9/11.

The station on the No. 1 line returns to service Saturday — three days short of the 17th anniversary of the terrorist attack on the World Trade Center.

The MTA chose to add World Trade Center to the name to honor the site, said officials.

“The station’s name references its location within the World Trade Center site as well as its legacy under Cortlandt Street, which existed above the station when the 1 line originally opened in July 1918 but was demolished during the construction of the World Trade Center in the late 1960s,” the MTA said in a statement.

The station will feature fewer columns, a new ventilation system, and a mosaic by artist Ann Hamilton, including text from the 1776 Declaration of Independence and the 1948 United Nations Universal Declaration of Human Rights.

The station took so long to reopen because the Port Authority kept it shuttered while it was busy working on the rest of the reconstruction of the World Trade Center complex.

The MTA has been rebuilding the station since 2015.
