The Uptown Hudson Tubes are a pair of tunnels that carry PATH trains between Manhattan, New York City, to the east and Jersey City, New Jersey, to the west.The tubes originate at a junction of two PATH lines on the New Jersey shore and cross eastward under the Hudson River.
The Downtown Hudson Tubes use a roughly east-southeast to west-northwest path under the Hudson River, connecting Manhattan in the east with Jersey City in the west. Each track is located in its own tube, [1] which enables better ventilation by the so-called piston effect. When a train passes through the tunnel it pushes out the air in front of ...
The tunnels were built in the first decade of the 20th century as part of the New York Tunnel Extension.The original plan for the extension which was published in June 1901, called for the construction of a bridge across the Hudson River between 45th and 50th Streets in Manhattan, as well as two closely spaced terminals for the LIRR and Pennsylvania Railroad (PRR).
After the tubes had been excavated, they were lined with 2.5-foot-wide (0.76 m) segmental cast-iron rings, each weighing 22 tons. The segments were bolted together and lined with 22 inches (56 cm) of concrete. [19] The two ends of the northern tube under the river met in September 1906; at that time it was the longest underwater tunnel in the ...
Each tube has a 29.5-foot (9.0 m) diameter, and the two tubes run 15 feet (4.6 m) apart under the Hudson River. The exteriors of each tube are composed of a series of cast iron rings, each of which comprises 14 curved steel pieces that are each 6 feet (1.8 m) long. The steel rings are covered by a 19-inch-thick (48 cm) layer of concrete.
Hudson Tubes may refer to a number of tunnels between New Jersey and New York under the Hudson River: Uptown Hudson Tubes, PATH tunnels that terminate at 33rd Street; Downtown Hudson Tubes, PATH tunnels that terminate at the World Trade Center; North River Tunnels, Amtrak and NJ Transit tunnels to Penn Station
Although the three portals are side by side in New Jersey, the north tube portal is one block west of the other two tubes' portals in New York City. [8] The north tube's eastern portal is near Eleventh Avenue between 38th and 39th Streets, while the center and south tubes emerge side by side at Tenth Avenue between 38th and 39th Streets. [8]
