Information: - A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. - Laurel Hill Tunnel is one of three original Pennsylvania Turnpike tunnels which were abandoned (this one in 1964) after two massive realignment projects. - The Ohio Turnpike, officially the James W. Shocknessy Ohio Turnpike, is a , limited-access toll highway in the U.S. state of Ohio, serving as a primary corridor to Chicago and Pittsburgh. The road runs eastwest in the northern section of the state, with the western end at the IndianaOhio border near Bryan where it meets the Indiana Toll Road, and the eastern end at the OhioPennsylvania border near Petersburg, where it meets the Pennsylvania Turnpike. The road is owned and maintained by the Ohio Turnpike and Infrastructure Commission (OTIC), headquartered in Berea. - New Jersey is a state in the Northeastern United States and mid-Atlantic regions of the United States. It is bordered on the north and east by New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, and on the southwest by Delaware. New Jersey is the fourth-smallest state but the 11th-most populous and the most densely populated of the 50 United States. New Jersey lies entirely within the combined statistical areas of New York City and Philadelphia and is the third-wealthiest U.S. state by per capita income as of 2014. - Ohio is an Eastern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus. - A controlled-access highway is a type of highway which has been designed for high-speed vehicular traffic, with all traffic flow and ingress/egress regulated. Common English terms are freeway (in Australia and parts of the United States and Canada), motorway (in the United Kingdom and Ireland) and expressway (some parts of Canada, parts of the United States, and many Asian countries). - Rays Hill Tunnel is one of three original Pennsylvania Turnpike tunnels which were abandoned (this one in 1968) after two massive realignment projects. The others included the Sideling Hill Tunnel, and farther west, the Laurel Hill Tunnel. - An immersed tube is a kind of underwater tunnel composed of segments, constructed elsewhere and floated to the tunnel site to be sunk into place and then linked together. They are commonly used for road and rail crossings of rivers, estuaries and sea channels/harbours. Immersed tubes are often used in conjunction with other forms of tunnel at their end, such as a cut and cover or bored tunnel, which is usually necessary to continue the tunnel from near the water's edge to the entrance (portal) at the land surface. - The Allegheny Mountain Range also spelled Alleghany, Allegany and, informally, the Allegheniesis part of the vast Appalachian Mountain Range of the eastern United States and Canada where it posed a significant barrier to land travel in less technologically advanced eras. It is a barrier range that has a northeastsouthwest orientation and runs for about 400 miles (640km) from north-central Pennsylvania, through western Maryland and eastern West Virginia, to southwestern Virginia. - The Delaware River is a major river on the Atlantic coast of the United States. Its watershed drains an area of in five U.S. statesNew York, New Jersey, Pennsylvania, Maryland and Delaware. Rising in two branches in New York state's Catskill Mountains, the river flows into Delaware Bay where its waters enter the Atlantic Ocean near Cape May in New Jersey and Cape Henlopen in Delaware. Not including Delaware Bay, the river's length including its two branches is . The Delaware River is one of nineteen "Great Waters" recognized by the America's Great Waters Coalition. - Sideling Hill Tunnel is one of three original Pennsylvania Turnpike tunnels abandoned (this one in 1968) after two massive realignment projects. The others are nearby Rays Hill Tunnel, and farther west, the Laurel Hill Tunnel. It was less expensive to realign the Turnpike than to bore a second tube for four lane traffic. Sideling Hill Tunnel is long. It was the longest of the original tunnels on the Pennsylvania Turnpike. The Ray's Hill Tunnel and Sideling Hill Tunnel are now part of the Pike2Bike Trail. Together, the two tunnels as well as the roadway are commonly known as the Abandoned Pennsylvania Turnpike. - --> The Pennsylvania Turnpike is a toll highway operated by the Pennsylvania Turnpike Commission in the U.S. state of Pennsylvania. A controlled-access highway, it runs for across the state. The turnpike begins at the Ohio state line in Lawrence County, where the road continues west into Ohio as the Ohio Turnpike. It ends at the New Jersey border at the Delaware RiverTurnpike Toll Bridge over the Delaware River in Bucks County, where it continues east as the Pearl Harbor Memorial Extension of the New Jersey Turnpike. - The Pennsylvania Turnpike Commission (PTC) was created in 1937 to construct, finance, operate, and maintain the Pennsylvania Turnpike. The commission consists of five members. Four members are appointed by the Governor of Pennsylvania. The fifth member is the Pennsylvania Secretary of Transportation. - Tuscarora Mountain Tunnel is one of four original Pennsylvania Turnpike tunnels still in active use . A second tube was bored in the late 1960s to ease traffic conditions . The Tuscarora Mountain tunnels measure 1.1 miles ( 1.8 km ) in length and are the second - longest active tunnels on the Pennsylvania Turnpike system . The 1.3 - mile - long ( 2.1 km ) Sideling Hill Tunnel is the longest overall , but was abandoned in 1968 . Allegheny Mountain Tunnel is the longest in active use . The Tuscarora Mountain Tunnel sits on the Huntingdon / Franklin County line . - Pennsylvania (Pennsylvania German: "Pennsylvaani"), officially the Commonwealth of Pennsylvania, is a state located in the northeastern and Mid-Atlantic regions of the United States. The Appalachian Mountains run through its middle. The commonwealth borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east. - The New Jersey Turnpike (NJTP), colloquially known to New Jerseyans as "the Turnpike", is a toll road in New Jersey, maintained by the New Jersey Turnpike Authority. According to the International Bridge, Tunnel and Turnpike Association, the Turnpike is the nation's sixth-busiest toll road and is one of the most heavily traveled highways in the United States. Having a total length of , the Turnpike's southern terminus begins at Interstate 295 (I-295) near the border of Pennsville and Carneys Point Townships in Salem County, one mile east of the Delaware Memorial Bridge. Its northern terminus is located at the George Washington Bridge in Fort Lee, Bergen County. The Turnpike is a major thoroughfare providing access to various localities in New Jersey, as well as Delaware, Pennsylvania, and New York. The route divides into four roadways between exit 6 and exit 14, with the inner lanes restricted to carrying only cars, and with the outer lanes for cars, trucks and buses. - The Delaware RiverTurnpike Toll Bridge is a four-lane steel arch-shaped continuous truss bridge that connects the Pennsylvania Turnpike's East-West Mainline with the main trunk of the New Jersey Turnpike, via the Pearl Harbor Memorial Extension (formerly known as the Pennsylvania Extension). The bridge crosses the Delaware River, connecting Bristol Township, Pennsylvania and Burlington Township, New Jersey. The bridge was closed to traffic on January 20, 2017, with a crack having been found in a steel truss. - The Allegheny Mountain Tunnel is a vehicular tunnel carrying the Pennsylvania Turnpike through the Allegheny Mountains. At this point, the Turnpike carries Interstates 70 and 76. When the tunnel was built, it was considered an "engineering marvel." - The Abandoned Pennsylvania Turnpike is the common name of a stretch of the Pennsylvania Turnpike that was bypassed in 1968 when a modern stretch opened to ease traffic congestion in the tunnels. In this case, the Sideling Hill Tunnel and Rays Hill Tunnel were bypassed, as was one of the Turnpike's travel plazas. The bypass is located just east of the heavily congested Breezewood interchange for Interstate70 (I-70) eastbound at what is now I-76 exit161.
