Planned Improvements
ESA Project Route
New tunnels will be constructed from the LIRR Mainline tracks in Queens, under Amtrak's Sunnyside Yard and LIRR's Existing Rail Yard, connecting to the existing 63rd Street Tunnel just beyond Northern Blvd. In Manhattan, new tunnels will be bored from the existing bellmouth structure at Second Avenue and 63rd Street, west and then south, under Park Avenue and Metro-North Railroad's four-track right of way.
Cross Section Looking West
At GCT, a new passenger concourse will be constructed in space currently occupied by Metro-North’s Madison Avenue Yard. Eight tracks and four wide platforms will be constructed, along with mezzanines and concourses, beneath Park Avenue at an elevation below GCT’s existing lower level.
