Grand Central Madison Opens After $11BN East Side Access Project

The MTA's East Side Access project opened Grand Central Madison, a new Long Island Rail Road terminal built in caverns roughly 150 feet beneath Park Avenue.

Grand Central Madison, the LIRR's new terminal beneath Grand Central built by East Side Access, opened on 25 January 2023, with full LIRR service to Grand Central from February 2023^[2][3]
The MTA calls it its largest capital project, with 40 miles of new track and a 350,000 sq ft terminal along Madison Avenue between 43rd and 48th Streets, for all 11 LIRR lines^[3]
Work began in September 2007 with two 640-ton tunnel boring machines; the concept dates to the 1960s and a lower tunnel level begun in 1969 sat dormant for three decades after the 1975 fiscal crisis^[2]
Grand Central was chosen in 1977; Hurricane Sandy in 2012 made the project a priority so LIRR trains could be diverted during East River Tunnel repairs^[2]
It is projected to carry over 160,000 passengers a day, adds 50% tunnel capacity into Manhattan, and saves commuters up to 40 minutes a day^[2][3]
