The MTA has released a new batch of images of the under-construction tunnels for its “East Side Access” project. For the uninitiated, East Side Access is the agency’s $10.8 billion plan to connect the Long Island Railroad with Grand Central Terminal. The project was initially scheduled to be completed by 2009, but, like so many large infrastructure projects, the East Side Access has been delayed. The project is now scheduled to open in 2023. All told, the project is expected to be $6.5 billion over budget.

Video> Sandhogs Blast Bedrock Beneath Grand Central Terminal

New York City’s Metropolitan Transportation Authority (MTA) has completed blasting through bedrock far below Grand Central Terminal for the East Side Access Tunnels that will connect the station with Sunnyside, Queens. As part of the announcement, one of the last production blasts from late March has debuted on YouTube. The video above reveals what has been transpiring beneath the streets of Manhattan during the tunneling process, and the sight is rather impressive. A camera caught the final blast that made way for a massive cavern. So far 2,424 production blasts have occurred below the commuter rail terminal station, which is celebrating its 100th birthday this year. For this explosion, sandhogs drilled more than 200 blast holes and loaded them with over 300 pounds of powder to guarantee a powerful explosion that could rival any action movie’s special effects.

There’s plenty of tunneling going on underneath the streets of Manhattan. On the west side, digging through the city’s bedrock has given way to interior station fit-ups for the Dattner-designed 7 line subway stations connecting Times Square to Hudson Yards as early as 2014. To the east, sandhogs continue to carve through solid rock for the $4.5 billion Second Avenue Subway Line while other crews outfit the tunnels with concrete and rebar.

Between the two, more massive caverns are being opened up beneath Grand Central Terminal, which turned 100 this month, that will extend the Long Island Railroad to the famed station from Sunnyside, Queens in 2019. The $8.24 billion East Side Access Project will allow commuters to bypass Penn Station and enter Manhattan 12-stories below Grand Central. Now, the MTA has released a dramatic set of photos from inside the 3.5-mile-long tunnel, revealing enormous cathedral-like spaces connected by perfectly cylindrical tunnels. Take a look.
