The MTA gained control of the Cortlandt Street station's reconstruction project in 2015. However, in January 2017, an independent engineer for the MTA said that the station's reopening could potentially be pushed back due to disagreements with station contractor Judlau Contracting. At that time, the MTA had spent $800,000 per month on the project, but it would need to spend four times as much money in order to meet the projected August 2018 deadline. The PANYNJ agreed to grant the MTA "full access" to the Cortlandt Street station in June 2017 once the temporary World Trade Center PATH entrance was demolished and the station's foundation was poured. The renovation included new Americans with Disabilities Act-compliant entrances with elevators, track-intrusion systems, fire alarms, Help Points, CCTV cameras, countdown clocks and air conditioning. A $1 million text-based marble mural by Ann Hamilton was installed in the station.
