The East Side Access Project Tunnels

East Side Access is a public-works project being undertaken by the Metropolitan Transportation Authority in New York City. Deep underground, rail tunnels are extending from Sunnyside, Queens, to a new Long Island Rail Road terminal being excavated beneath Grand Central Terminal. Construction began in 2007, with an estimated cost of $6.3 billion and completion date of 2013. Since then, the cost estimate has been raised to $8.4 billion, and the completion date moved back to 2019.
