North River Tunnels

The North River Tunnels are a pair of tunnels that carry Amtrak and New Jersey Transit rail lines under the Hudson River between Weehawken, New Jersey and Pennsylvania Station in Manhattan, New York City. Built between 1904 and 1908 by the Pennsylvania Railroad (PRR) to allow its trains to reach Manhattan, they opened for passenger service in late 1910.

Design and construction

Led by Chief Engineer Charles M. Jacobs, the tunnel design team began work in 1902. After plans were complete in 1904, the first task was digging two shafts, one just east of 11th Avenue in Manhattan and a larger one a few hundred yards west of the river. The Weehawken Shaft was completed in September 1904 as a concrete-walled rectangular pit, 56 by 116 ft at the bottom and 76 ft deep.

When the shafts were complete, O'Rourke Engineering Construction Company began work on the tunnels proper. The project was divided into three parts, each managed by a resident engineer: The "Terminal Station" in Manhattan; the "River Tunnels", east from the Weehawken Shaft and under the Hudson River; and the Bergen Hill tunnels, west from the Weehawken Shaft to the tunnel portals on the west side of the Palisades. (At the time, "North River Tunnels" referred to the tunnels east of the Weehawken Shaft; in later years the term has come to include the Bergen Hill tunnels as well.) The tunnels were built with drilling and blasting techniques and tunnelling shields, digging west from Manhattan, east and west from Weehawken, and east from the Bergen portals. 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 world.

North River (Cacapon River)

North River is a tributary of the Cacapon River, belonging to the Potomac River and Chesapeake Bay watersheds. The river is located in Hampshire and Hardy counties in the U.S. state of West Virginia's Eastern Panhandle. The mouth of North River into the Cacapon is located at Forks of Cacapon. From its headwaters to its mouth, the North River spans 52.4 miles (84.3 km) in length.

Headwaters and course

South Branch Mountain to Rio

North River's headwaters comprise two streams that converge in the southeastern hollows of South Branch Mountain (3028 ft) in Hardy County. From its source, the river flows east through the communities of Inkerman and Rock Oak along North River Road (County Route 1) where it is joined by Grassy Lick Run. North River continues to flow east as a shallow stony stream and after it passes through a gap in Short Mountain (2864 ft), it acts as the border between Hardy and Hampshire counties. It is in this stretch that the river is home to the Rio Turtle, a large turtle-shaped rock painted to resemble a turtle. The river then enters exclusively into Hampshire County where it meets the community of Rio and Sperry Run, which flows in from the south.
