Grand Central Terminal is getting a new entrance for Metro-North commuters and future Long Island Rail Road riders.

The construction of the E. 47th St. entrance, between Park and Lexington Avenues, broke ground Monday as part of the East Side Access Project -- a $6.3 billion plan to build four two-train platforms to extend LIRR's lines and connect to Grand Central.

MTA officials said the new connection will dramatically shorten travel time for commuters traveling to the east side of Manhattan.

The $14 million entrance is slated to open in September 2011, while the new platforms are expected to be completed by the end of 2016.
