The Metropolitan Transportation Authority announced today it's signed a 99-year lease with Related Companies and Oxford Properties Group to develop its Hudson Yards property into a mixed-use community.

The MTA says the 26-acre neighborhood on Manhattan's West Side will include 12 acres of public open space, a public school and 12 million square feet of commercial and residential development.

"This is a tremendously exciting development project that together with the extension of the 7 line will turn this area into a vibrant residential and commercial neighborhood,” said MTA Chairman and CEO Jay Walder. "We were also able to maximize value for the MTA and provide a new revenue stream to support many of our vital capital projects."

The developers will build a deck over the Long Island Rail Road tracks to avoid service disruptions.
