The MTA has finalized a $57 million deal that it says will shave more than a year off of its planned overhaul of its busiest LIRR station on Long Island — Hicksville.

The Metropolitan Transportation Authority Board last week unanimously approved the $56.7 million contract to the joint venture of Railroad Construction Company/Citnalta to rehabilitate the 55-year old station.

The work will include installing new platforms, canopy roofs, drainage systems, platform waiting rooms, staircases, escalators, lighting, and signs. The work is part of a larger $120 million effort at the station that will include the construction of more than 3,000 feet of new track to connect to a nearby train storage area.

Although initially slated to take nearly three years, the LIRR said, by taking one track and platform out of service for most of the summer of 2017, it expects to be able to finish the work in 22 months.

“Hicksville station is the LIRR’s third busiest station — topped only by Penn and Jamaica — and it’s a key transfer point for customers on the Port Jefferson and Ronkonkoma branches,” Gov. Andrew M. Cuomo said in a statement. “To have such an important transportation hub encumbered by construction for three years was out of the question.”

Work on the project is expected to begin in July.
