The renovations would cost between $800 million and $1 billion. There were two options: a partial closure for three years or a full closure for 18 months. It was later announced that the MTA had chosen the 18-month full closure option. To provide alternate service, the MTA devised preliminary mitigation plans in which it proposed adding shuttle bus, ferry, and subway service; adding bus and high-occupancy vehicle lanes; extending train routes; and providing free or improved transfers. The MTA named Judlau Contracting and TC Electric as the project's contractors on April 3, 2017. At this time, the duration of the shutdown was shortened to 15 months, so the shutdown would begin in April instead of in January. In June 2018, as part of a lawsuit settlement, additional changes were made to the shutdown mitigation plans.
