East Side Access Connection

East Side Access Connection

The East Side Access (ESA) Project is a connection of the New York Metro from Long Island Railroad (LIRR) to East Side Manhattan. The project includes a new station, East Side Station, linked to the Grand Central station in Manhattan.

The objective of the line is to relieve capacity congestion at Penn Station New York (PSNY) and to provide direct access to East Midtown Manhattan. It is the largest construction project ever undertaken by the Metropolitan Transportation Authority.
