In a press conference held yesterday at Madison Square Garden, New York governor Andrew Cuomo detailed his plans for the complete—and very much needed—overhaul of Pennsylvania Station. The transportation hub is the busiest in North America, serving some 650,000 passengers each day, though the current space was designed to accommodate only 200,000. The state, working with Amtrak and the Metropolitan Transportation Authority, is seeking developers for two separate projects: one to improve the existing station by broadening its corridors, bringing natural light into the space, and expanding its retail offerings; and another to transform the neighboring James A. Farley Post Office into a train hall for Amtrak, New Jersey Transit, the Long Island Rail Road, and the new AirTrain to LaGuardia Airport.

The proposal would see the return of glass ceilings to Penn Station, reminiscent of its original 1910 building.

Combined, the projects, which will double Penn Station’s size, are estimated to cost $3 billion, funded by a public-private partnership. Ground is expected to be broken in 2016 with construction to be completed in the next three years. The renovation is just one part of the governor’s modernizing vision for New York State’s transportation network, which he touted in a press conference as “the biggest construction program in our state’s history.” Cuomo seeks to improve roads and bridges as well as build new air and rail terminals, a new Hudson River rail tunnel, and a third track for part of the Long Island Rail Road.

The current subterranean Penn Station is not the first iteration of the station: The original Beaux Arts structure was built in 1910 and designed by McKim, Mead & White.
