NJ Transit expects to deliver 46 million riders across the Hudson River this year, a 150 percent increase in the past decade and a quadruple increase since 1984. If Gov. Chris Christie does a turnabout and decides to support the ARC tunnel, it will double the capacity of the rail lines across the Hudson, which are owned and also used by Amtrak.
In addition, the Hudson River crossings operated by the Port Authority of New York and New Jersey carry a total of 89 million vehicles eastbound each year. The George Washington bridge transports the highest number, 52 million. The Lincoln Tunnel has the second highest vehicular traffic, 20 million eastbound trips a year. The Holland Tunnel, the oldest of the crossings, carries about 16 million vehicles eastbound annually.
