A huge public works project is currently under construction in New York City, connecting Long Island to Manhattan's East Side. 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. When finished, the line will accommodate 24 trains per hour at peak traffic, cutting down on commute times from Long Island, and opening up access to John F. Kennedy International Airport from Manhattan's East Side. Collected here are images of the progress to date, deep beneath Queens and Manhattan.
