By September 2017, much of the communications, power, and ventilation infrastructure was being installed, but contractor work and Port Authority utility relocation were significantly delayed. According to the MTA's Capital Program Oversight Committee, the contractor had to more than double its productivity to ensure an October 2018 opening, with substantial completion in December 2018. In April 2018, several news sources affirmed the possible reopening date of October 2018. By June, the station wiring was complete, architectural finishes and turnstiles were being installed, and elevators and escalators were being installed. Station name signs with the text "World Trade Center" were being installed along the platform walls by August 2018. The reconstruction of the station ultimately cost $181 million, up from earlier projections of $158 million and $101 million. At that point, the television station WCBS-TV estimated that over a million trains had passed through the station without stopping.
