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.
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.
