"A ceremonial groundbreaking was set for (June 8) in North Bergen, N.J., the site of the first small piece of what could be the biggest transit project in the country.
The Mass Transit Tunnel - formerly known as the Trans-Hudson Express and, before that, Access to the Region's Core - more than 15 years after it was conceived is expected to take eight years to complete, bears a current price tag of $8.7 billion. That is about $6 billion less than the so-called Big Dig highway tunnel in Boston cost but about $6 billion more than the project's original price.
The Hudson tunnel was designed to help ease the jam-packed rides that rail commuters from the west have long endured. New Jersey Transit, which runs as many as 23 trains an hour through a century-old tunnel into Pennsylvania Station in New York, has said that it is nearing maximum capacity. The riders of those trains share Penn Station with passengers of the Long Island Rail Road and Amtrak.
That tunnel would bring trains from the suburbs of North Jersey and would end in a bilevel station to be built about 180 feet below 34th Street between Sixth and Eighth Avenues.
That station, dubbed the Penn Station Expansion, was originally designed to connect to Penn Station so that Amtrak and New Jersey Transit would have another route in and out of New York. But the project's planners threw out that idea when they decided that they needed to cut much deeper under the city.
Some mass transit advocates have insisted that the tunnel connect to either Penn Station or Grand Central Terminal, or both, to be useful to many of the commuters. Others have argued that the proposed station, 18 stories below ground, will be too difficult to evacuate in a fire or other emergency."
