Abstract
The Cross Harbor Freight Movement Project is currently in the Environmental Impact Statement phase. The scheme is addressing alternative solutions to transport freight across the Upper Bay of New York Harbor, from New Jersey through to Brooklyn, Queens and Long Island. Amongst the alternatives being assessed are two tunnel options; from the north shore of Staten Island through to Brooklyn, and from Jersey City to Brooklyn. These tunnels are approximately 30,000 feet in length, and with up to 7,000 feet under the Harbor, would make it one of the longest undersea crossings in the world. The paper addresses the development of the project, from the Major Investment Study through to the current EIS, and describes the tunnel schemes that are being taken forward. The geological conditions that will be encountered, proposed construction methods, and the ventilation issues associated with such major undersea tunnels will all be described.
