The Pennsylvania Turnpike is a toll highway system in the state of Pennsylvania, USA. The turnpike system encompasses 532 miles (855 km) in three distinct sections. Its main section, extending from the Ohio state line in the west to the New Jersey state line in the east, stretches 359 miles (578 km). Its Northeast Extension, extending from Valley Forge in the southeast to Wilkes-Barre and Scranton in the northeast, stretches 110 miles. Its various highway segments in western Pennsylvania cover 62 miles (100 km).
The highway serves most of Pennsylvania's major urban areas, with the main east-west section serving the Pittsburgh, Harrisburg, and Philadelphia areas and its Northeastern Extension serving the Allentown/Bethlehem and Scranton/Wilkes-Barre areas.

The majority of the Turnpike system is operated as a ticket system toll road, in which a driver receives a paper ticket on entry and pays on exit, with the amount pre-calculated based on entrance and exit points. Most of the system's access points are simple "trumpet" interchanges, with a toll barrier located between the interchange itself and the local connector road. Between 1940 and 1997, the road had three "mainline" barrier plazas - one at Gateway (at the Pennsylvania/Ohio state line), connecting to the Ohio Turnpike, one at the Delaware River Bridge near Bristol, where the Turnpike crosses the Delaware River and connects with the New Jersey Turnpike, and one on the Northeastern Extension at Clarks Summit, where it connects with Interstate 81 near Scranton.
In 1997, the new Mid-County exit, connecting Interstate 476 with the Turnpike, opened. It doubles as a mainline and interchange barrier. In 2002, the Gateway barrier was converted to an all-cash plaza, and a new mainline barrier, at Warrendale, was added. With the opening of the new Warrendale barrier, the Turnpike between Gateway and Warrendale is toll-free and gives motorists direct access to the James E. Ross Highway, Interstate 79, and two local roads. A similar approach was used between the Wyoming Valley interchange and Clarks Summit on the Northeastern Extension, allowing for the construction of the Keyser Avenue interchange, along with a new coin-drop booth north of the exit. This will also be implemented when the Turnpike/Interstate 95 exit is completed in Bristol, allowing I-95 to access the Turnpike with a high-speed interchange.
E-ZPass is accepted at all toll booths, with one operating exit (Virginia Drive near Fort Washington) and one proposed exit (Great Valley near Malvern) being accessible to E-ZPass customers only.
Proposals to use the grade and tunnels for a toll road were made starting in late 1934. The road would bypass the steep grades on Pennsylvania's existing major east-west highways - US 22 (William Penn Highway) and US 30 (Lincoln Highway) - and offer a high-speed four lane route free of cross traffic. The Pennsylvania Turnpike Commission was created by law on May 21, 1937, and construction began October 27, 1938 with the removal of water from the unfinished tunnels.
In October 1, 1940 the first section of Turnpike opened, running from US 11 near Carlisle (southwest of Harrisburg) west to US 30 at Irwin (east of Pittsburgh). As built, the majority of the road was four lanes, but it narrowed to one lane in each direction for the seven tunnels (the South Pennsylvania had begun work on nine, but two - the Quemahoning Tunnel and Negro Mountain Tunnel - were bypassed by the Turnpike). Despite the existence of the railroad right-of-way, much of the new Turnpike was built on a new, straighter alignment, as engineering had progressed much since the days of the railroad.
Unlike earlier U.S. freeways, mostly in the New York City area, which were restricted to cars, the Turnpike allowed all traffic. Like the German Autobahn on which it was loosely based, there was no enforced speed limit on most of the road--some cars could travel at 100 mph (160 km/h) and traverse the entire 110 mile (177 km) original segment in slightly over an hour. The phenomenon of highway hypnosis began to afflict motorists on some of the long, straight segments--especially on the 21 mile (34 km) section of Turnpike between the Blue Mountain Tunnel and the eastern terminus at Carlisle.
The result of this project was the "twinning" (construction of a second, parallel, two-lane tunnel) of four tunnels, and the outright bypass and closure of the other three. The Blue, Kittattiny, Tuscarora, and Allegheny Mountain Tunnels were expanded through the construction of new tunnels identical to the original tunnels in design, construction methods (dynamite and wooden supports), and length. After the second tunnels were completed at each location, the original tunnels were temporarily closed for rehabilitations that included upgrades in forced air ventliation and lighting systems.
The Sideling Hill, Rays Hill, and Laurel Hill tunnels were closed and bypassed. The adjacent Sideling Hill and Rays Hill tunnels were replaced with one stretch of highway that climbed over those mountains, while the Laurel Hill Tunnel was bypassed with a long rock cut through the mountain. The three bypassed tunnels are still in existence.
The 13-mile stretch that contained the Sideling Hill and Rays Hill Tunnels are now part of a popular tourist attraction known as the Abandoned Pennsylvania Turnpike, which most of it was sold to Southern Alleghenies Conservancy in 2001. The Laurel Hill stretch, which is much shorter at about 2 miles, is still owned by the PTC and tresspassing is prohibited.
Although the extensions were dropped, the commission also looked into a major expansion project in the early 1970s in which the east-west mainline would be expanded into a "dual-dual" eight-lane highway similar to that of the New Jersey Turnpike between Jamesburg and Newark. With the dual-dual configuration, the inner two lanes would be car-only lanes while the outer lanes would be for trucks, buses, and trailers.
The dual-dual would have required major realignments, similar to that of the Sideling Hill relocation, but most of the original infrastructure would have remained intact in most places. This plan was dropped by 1976, but since 1980, most of the original plan was implemented on a smaller scale. Truck climbing lanes were built on the Allegheny Ridge, and the roadway was expanded to six lanes between the Norristown and Philadelphia exits. The six-lane configuration was planned or in the process of being constructed between the proposed Great Valley Slip Ramp and Norristown, between Philadelphia and the New Jersey Turnpike, and on the Northeast Extension between Mid-County and Lansdale.
However, heavy trucks may well be better served by remaining on the Turnpike, as I-68 is full of steep mountain grades that are anything but truck-friendly. There is a five-mile long, 7% grade -- climbing eastbound, descending westbound -- at Cheat Lake, WV, about 10 miles east of Morgantown, and there is a 13-mile long grade (climbing westbound, descending eastbound), parts of which get as steep as 6%, between Big Savage Mountain and Cumberland in Maryland. This 13-miler is notorious for its length as well as the 40-mph truck speed limit through the last few miles of the downgrade, as one approaches downtown Cumberland.
Another possible Shunpiking route that utilizes largely four-lane expressways and freeways to avoid the Turnpike actually starts in Ohio, at the Interstate 76/Interstate 80 split. Enter Pennsylvania on I-80 rather than on the Turnpike, and go all the way to Exit 161 (PA 26, the State College exit). Take PA 26 roughly 10 miles down to U.S. Route 322, and go east. From State College to Harrisburg, about 90% of the length of US 322 is full freeway; a short segment immediately east of State College is two lanes, and the Lewistown Narrows segment and a short stretch north of Harrisburg are four lanes with driveway accesses. Between Harrisburg and the Philadelphia area, the best Shunpiking route is probably I-283 east out of Harrisburg to PA 283, then PA 283 east to Lancaster, then US 30 east to US 202 east to I-76/Schuylkill Expressway east.
Yet another alternative is to take I-68 Westbound to Maryland Exit 14. Go north to U.S. 40 and continue west on U.S. 40 toward Uniontown, PA. Cross the Monongahela River on U.S. 40 and then go north on PA 43 to rejoin I-70. Again, this is a much better alternative for cars than for heavy trucks, not only because of the steep grades on I-68, but also because of at least two more steep grades -- one 8%, the other an amazing 13% -- on that part of US 40.
The Pennsylvania Turnpike Commission is currently reconfiguring and expanding the Turnpike to meet modern traffic needs. Parts of the original Irwin-Carlisle section is being rebuilt with new roadbeds (using the original concrete and later macadam paving), and long-duration "Superpave" macadam asphalt (similar to a process used on I-95 in Delaware between U.S. Highway 202 and the Pennsylvania State Line in 2000).
Between Valley Forge and the Northeast Extension, the highway is being expanded from four lanes to six, and with the completion of the entire I-95/Turnpike exit (along with the building of the paralleling Turnpike Connector Bridge), the entire Delaware River Extension will have six lanes.
Other projects include the conversion of the Gateway Toll Plaza from a traditional toll booth to an all-cash plaza with high-speed lanes, for E-Z Pass tag users, and the relocation of the ticket system at a new toll plaza in Warrendale. "Slip Ramps," for E-Z Pass tagholders, have been built near Fort Washington (Virginia Drive), with another planned for the Great Valley Corporate Center near Malvern. A similar six-lane expansion has also been planned for the Northeast Extension between its junction in Norristown to Lansdale, and on the mainline turnpike between Valley Forge and the planned Great Valley slip ramps.
On Memorial Day Weekend, 2005, the Pennsylvania Turnpike system became the first highway system in Pennsylvania to have a 65 mph speed limit on the entire length (except for the tunnels themselves, and the winding 5.5-mile (9 km) eastern approach to the Allegheny Mountain Tunnel) of both the mainline turnpike and the Northeast Extension. This is the first time since the mandated 55 mph (88 km/h) speed limit was implemented in 1974 that a motorist can cross the entire state of Pennsylvania at 65 mph (105 km/h) without having to travel at lower speeds for extended periods.
A project * is currently planned to install a high speed interchange between the two highways. In addition to the new interchange, the PTC will expand the existing four-lane road to six lanes east of the Philadelphia interchange (U.S. Highway 1), build a new facility at milepost 353 to 355 to collect toll tickets, build a new eastbound-only exact-change facility between the new exit and the Delaware Valley interchange (U.S. Highway 13), and convert the present Delaware River Bridge toll barrier (which currently collects tickets) to a westbound-only exact-change facility. In addition, both the PTC and the New Jersey Turnpike Authority will build a twin parallel bridge over the Delaware River, with the NJTPA itself expanding the mainline Turnpike itself from its current six lanes to a dual-dual configuration like that found north of Jamesburg. This project will complete I-95 from Miami, FL to Houlton, ME. Construction is expected to start in late 2006 or early 2007 and will cost approximately $500 million.
