On February 24, 2016, the MTA allocated $66 million to speed up the construction of the first phase so that it could open in December. However, by June, the project was not being built at a rate that would allow a December 2016 completion. Concerns about the line's timely opening persisted through October and November, with key systems such as elevators, escalators, and fire alarms not having been tested. Test trains started running on October 9, 2016, and out-of-service Q trains started running through the subway in November 2016.
