Routes

The Pennsylvania Turnpike is a toll highway system operated by the Pennsylvania Turnpike Commission 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 Plymouth Meeting in the southeast to Wilkes-Barre and Scranton in the northeast, stretches 110 miles (177 km). 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

When the Pennsylvania Turnpike opened in 1940, it was the first long-distance rural highway in the United States and was popularly known as the "tunnel highway" because of the seven mountain tunnels along its route.

First section

The turnpike was partially constructed on an unused railroad grade constructed for the aborted South Pennsylvania Railroad project, and six of its seven original tunnels (all tunnels with the exception of the Allegheny Mountain tunnel) were first bored for that railroad.

Proposals to use the grade and tunnels for a toll road were made starting in late

Unlike earlier U.S. highways, 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 160 mile (256 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.

Turnpike expansion

With the success of the original 160 mile (256 km) segment, the turnpike commission planned to expand the original Turnpike to a cross-state route, connecting Philadelphia with Pittsburgh with a high-speed route. This was shelved with the onset of World War II, but with the war's end, the turnpike commission resumed construction.

Western expansions

Western extensions, that mostly serve the Pittsburgh Area were constructed from the 1990s until the present. The James E. Ross Highway and the Amos K. Hutchinson Bypass were completed by 1994, and the James J. Manderino Highway, a West Virginia-to-Pittsburgh route, (Mon/Fayette Expressway) is approximately 50% completed with the last major link to Pittsburgh under design. The first section of the Pittsburgh Southern Beltway (from the Mon/Fayette Expressway to the Pittsburgh International Airport) has been completed and is open to traffic. Environmental Impact Statements (EIS) for the two remaining sections are in preparation

Competing highways

The Pennsylvania Turnpike Commission originally proposed a statewide system of additional toll highways, but these plans were rendered unnecessary with the inception of the U.S. Interstate Highway system in 1954. A toll-free east-west competitor – Interstate 80 – opened on August 29, 1970 across northern Pennsylvania, forming a route that was more direct for New York-Chicago traffic. In 2007, however, the Commonwealth of Pennsylvania leased Interstate 80 to the Turnpike Commission. Under this lease agreement, this will allow the Turnpike Commission to convert Interstate 80 to a toll highway.^[1][2]

The turnpike is part of the U.S. Interstate Highway System, and is signed with the following route numbers:

• Interstate 76. Interstate 76 comprises the majority of the system, starting at the turnpike's western terminus at the Ohio state line. Interstate 70 joins the turnpike at New Stanton, Interchange 75, and runs concurrently with Interstate 76 until leaving the turnpike at Breezewood, Interchange 161 (the only other tolled section of I-70 is on the Kansas Turnpike
  ).
• Interstate 276
  . Interstate 76 leaves the turnpike mainline at Valley Forge/Philadelphia, Interchange 326. At that point, the turnpike becomes Interstate 276 until it meets with a spur of the New Jersey Turnpike at the turnpike's eastern terminus at the Delaware River.
• Interstate 476. The Northeast Extension, which meets the turnpike mainline at milepost 333.5 (the interchange is designated as Exit-20, the milepost marker for I-476), is signed as part of Interstate 476. This section was originally signed as Pennsylvania Route 9 before redesignation in the 1990s.
• Interstate 95. The turnpike mainline now crosses Interstate 95 but does not have a direct connection to that route. An interchange is currently being constructed in this area. Once the Pennsylvania Turnpike/Interstate 95 Interchange Project northeast of Philadelphia is completed, the section of the turnpike east of that interchange (now Interstate 276) will be redesignated as Interstate 95.

The majority of the Turnpike 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 Township, 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 1992, the new Mid-County exit, connecting

E-ZPass is accepted in designated lanes at all toll plazas. The Virginia Drive exit near Fort Washington is only accessible to E-ZPass customers. Additionally, the proposed Great Valley exit near Malvern, and the Philadelphia Park exit near Bensalem, are expected to also be E-ZPass-only.

On

After it opened as the nation's first superhighway, the Pennsylvania Turnpike was popularly known as the "Tunnel Highway." Postcards and other souvenirs promoted this name because, immediately after opening, the original stretch of the turnpike sported seven tunnels through Pennsylvania's Appalachian Mountains.^[7] These tunnels, in order of east to west, bored through Blue Mountain, Kittattiny Mountain, Tuscarora Mountain, Sideling Hill, Ray's Hill, Allegheny Mountain, and Laurel Hill.

Modernization

While the highway was built as a four-lane, limited-access highway, the seven tunnels each held only two travel lanes. Traffic was squeezed from four lanes to two at each tunnel portal, and traffic proceeded through each tunnel without being divided from oncoming traffic. By the 1960s, this situation was creating long delays at each tunnel bottleneck. To alleviate this overcrowding, the turnpike commission studied ways to either expand or bypass each tunnel.

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 trespassing is prohibited.

Lehigh Tunnel

The Northeast Extension of the Pennsylvania Turnpike contains the Lehigh Tunnel, a 4,461-foot tunnel through Blue Mountain. The tunnel was named "Lehigh Tunnel" so as not to cause confusion with the existing Blue Mountain tunnel on the mainline. The tunnel was originally to be named for Turnpike Commission chairman Thomas J. Evans, but this was changed due to his July 25, 1967 conviction for conspiracy to defraud the Turnpike Commission of $19 million.^[8]

The Lehigh Tunnel was originally a two-lane tunnel, in the manner of the highway's original seven tunnels, until it was "twinned" in the early 1990s. The new Lehigh Tunnel is the only tunnel built by the Turnpike Commission using the

The Allegheny Mountain Tunnel, currently the longest tunnel complex on the entire Turnpike system (only the bypassed Sideling Hill Tunnel was longer), and the only one of the original seven tunnels not to have been originally bored for the aborted Southeast Pennsylvania Railroad project, is currently the most problematic tunnel for the turnpike. In 1996, the turnpike commission began a study on how to address this tunnel, which was suffering from a low traffic capacity and deterioration. The study recommended that a bypass (known as the "Brown Cut") be blasted through the adjacent mountain, but a high pricetag and opposition from landowners and environmental groups shelved this project. The commission is currently realigning the approach roads to the tunnel while examining more acceptable ways to address the capacity and age-related issues of the tunnels.

Soon after the mainline was built, the Pennsylvania Turnpike Commission proposed a number of extensions as part of a 1,000 mile (1,600 km) Turnpike network. These plans were dropped in the mid-1950s in favor of the Interstate Highway System. The proposed network included the following:

• Chester Extension--now Interstate 476 between Chester and the Northeast Extension
• Northwest Extension--now Interstate 79, this would connect with the New York State Thruway near Erie.
• Southwest Extension--now Interstate 79, this would be a continuation of the Northwest Extension to West Virginia.
• Gettysburg Extension--now the U.S. Route 15 Gettysburg Bypass
• Northeastern Extension (Clarks Summit to New York State Line)--now Interstate 81. This would also connect with the New York State Thruway in Rochester.
• Philadelphia Loop Connection--now
  Interstate 276
• Sharon Lateral Connection--now Interstate 80

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 Sideling Hill, 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.

Today, the Turnpike is controlled by the Pennsylvania Turnpike Commission, handles over 172 million vehicles per year, and employs nearly 2,200 people.

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

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 building unmanned "Slip Ramps" between existing interchanges. These have been built for E-Z Pass tagholders only,^[9] 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 Downingtown interchange, the westernmost of the Turnpike's Philadelphia suburban interchanges.

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 Commonwealth of Pennsylvania at 65 mph (105 km/h) without having to travel at lower speeds for extended periods.

Future Slip Ramp Locations

• PA Route 29 at about milemarker 319 (East Whiteland) ^[10]
• Lafayette Street & U.S. 202 at about milemarker 331 (Bridgeport/Norristown) ^[11]
• PA Route 132 & Street Road at about milemarker 352 (Philadelphia Racetrack) ^[12]

The turnpike commission is also considering slip ramps near the New Stanton area as a part of the ongoing total reconstruction process going on between MP67 (IRWIN) and MP75 (New Stanton)[1]

Interchange with Interstate 95 project

A project [2] 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 (

In November 2006, Pennsylvania Governor Ed Rendell and former Pennsylvania House Speaker John Perzel separately raised the idea of a long-term lease of the turnpike to a private group as a means of raising money to improve other infrastructure within the state, following examples of similar toll road lease arrangements in Illinois, Indiana, Texas, and Virginia. Although no plans are immediately in place, Rendell and Perzel have speculated that a lease of the system could bring anywhere from $2.5 to $30 billion to the state. [3]

This idea faced criticism from the legislature, and instead a plan was created to lease Interstate 80 to the Pennsylvania Turnpike Commission and place tolls on it to fund transportation. However, this plan faced opposition from many people in Northern Pennsylvania who feared tolls on I-80 would hurt the economy of the region, which led Rendell to revive the plan of leasing the Pennsylvania Turnpike. In October 2007, 34 companies submitted 14 proposals to leasing the turnpike.^[13]

Until October 25, 2000, exit numbers were numbered in sequence. On that day, mile-based exit numbers were added, and the old numbers were moved onto smaller "old exit" tabs. This was done at the same time the Pennsylvania Department of Transportation (PennDOT) did a similar upgrade on all of the state's Interstate Highways.

For exits on the northeast extension, see Interstate 476.
