Analysis of information sources in references of the Wikipedia article "North River Tunnels" in English language version.
The story of ARC began in 1995 with the start of a "Major Investment Study" that reviewed 137 alternative transportation improvements that would get commuters from central and northern New Jersey out of their cars, and into Manhattan faster, cheaper, and with less harm to the environment. After four years of study, the list was narrowed down to a few finalists in 1999. From 1999 to 2003, the feasibility of each of those plans (exactly where the tracks would be laid, and how they would connect to Penn Station) was studied, and the ultimate plan ironed out. From 2003 to 2009, the final plan — two new rail tunnels leading to a new lower level of Penn Station — was the subject of an Environmental Impact Statement (EIS).
