The City of New York has been planning for years to bring the LIRR to Manhattans Grand Central Station. The Tunnels needed to make this happen have been under construction for some years now, and the project has already gone billions over budget. The once $6.3 billion price tag jumped in 2006 to $8.24 billion and could increase more. Many skeptics fear the project will turn into New York's very own "Big Dig". The project was once slated to be done by 2015, but is now scheduled to last until August 2019. Below are some impressive images of the tunnels progress.
