Crews digging a tunnel through Manhattan bedrock for the Long Island Railroad have reached Grand Central Terminal — a milestone in the MTA's East Side Access mega-project.
The tunnel boring machine had spent eight months digging from 63rd Street and Second Avenue. A second boring machine is expected to reach Grand Central by the end of the summer.
Workers will next use dynamite to create a chamber deep beneath Grand Central that will become a new station and concourse at Park Avenue and 42nd Street for LIRR trains arriving on the East Side.
