The transcontinental Interstate 80 (I-80) is designated across northern Pennsylvania as the Keystone Shortway, officially the Z.H. Confair Memorial Highway.  This route was built mainly along a completely new alignment, not paralleling any earlier U.S. Routes, as a shortcut to the tolled Pennsylvania Turnpike and New York State Thruway. It does not serve any major cities in Pennsylvania, and serves mainly as a cross-state route on the Ohio- New York City corridor. Most of I-80's path across the state goes through hilly and mountainous terrain, with relatively flat areas toward the western tier of the state.
Interstate 80 serves smaller cities in northern Pennsylvania including Sharon, Clarion, DuBois, Bellfonte, Milton, Bloomsburg, Hazleton, and Stroudsburg. It also passes close to two larger cities– Williamsport and State College. Most of the route in Pennsylvania is within a rural setting, with the exception of the Stroudsburg area, which is closer to the New York City and Philadelphia metropolitan areas and is suburban and populated.
From the state of Ohio, I-80 enters the Western Pennsylvania area which encompasses Mercer, Venango, Butler, Clarion, Jefferson, and Clearfield Counties. I-80 intersects I-376 (serving the Pittsburgh International Airport and on to Downtown Pittsburgh) and I-79 (serving Erie to the north and Pittsburgh to the south) in Mercer County in Shenango and Findley Township respectively. Jefferson County at mile marker 73 is known for the city of Punxsutawney, the location of the famous groundhog Punxsutawney Phil who predicts the weather on Groundhog Day. In Clearfield County, I-80 reaches its highest elevation east of the Mississippi River, 2,250 feet (690 m), although other interstate highways east of the Mississippi, including I-26 in North Carolina and Tennessee, reach higher elevations. This point is just east of Exit 111. A sign prominently displays this unusual fact about the Interstate. At mile marker 101, I-80 passes by the city of Dubois.
I-80 enters Centre County around mile marker 138 and intersects I-99 at exit 161, the main connecting point to the Pennsylvania Turnpike ( I-76 and I-70) and the Pennsylvania State University. US 220 is concurrent between exits 161 and 178 where it heads towards Lock Haven, home to the Lock Haven University of Pennsylvania.
Around mile marker 191, Pennsylvania Route 880 follows a parallel alignment within the median between the eastbound and westbound lanes for a half-mile, an unusual arrangement in Pennsylvania. It is common to see horse-drawn carriages from the nearby Amish communities travelling this highway-within-a-highway.
I-80 enters the Northeastern Pennsylvania area to include points Northumberland County and east to New Jersey. In Montour County at mile marker 224, it approaches the Bloomsburg area, home to the Bloomsburg University of Pennsylvania. I-80 also passes by the Wilkes-Barre/ Scranton area in Luzerne County. At exit 260, a connection can be made via I-81 to Harrisburg to the south and Wilkes-Barre and Syracuse, NY to the north.
I-80 intersects I-476 (the Pennsylvania Turnpike NE Extension) at exit 277 in Carbon County for connections to Allentown and Philadelphia to the south. Exit 277 also serves PA 940 and Hickory Run State Park. Just east of the PA Turnpike, I-80 crosses into Monroe County. Exit 284 connects to PA 115 near Blakeslee and Lake Harmony. Exit 293 is an interchange with I-380 near Pocono Pines for a connection to I-84 to New England and Scranton towards the north. Between exits 293 and 298, there is a rest area on the eastbound side with public restrooms and picnic tables, but no food or gas.
Around exit 298, I-80 approaches the Stroudsburg and East Stroudsburg areas, a more suburban and populated region home to the East Stroudsburg University of Pennsylvania and the ski resort areas of the eastern Pocono Mountains. Stroudsburg is also the seat for Monroe County. PA 611 follows I-80 closely through the area between exits 298 and 310, acting as a local alternative. Exit 298 is only a westbound exit and eastbound entrance, connecting to PA 611 in Scotrun. West of exit 298, PA 611 heads northward and away from I-80. Exit 299 serves PA 715 in Tannersville, as well as a local outlet mall. Exit 302 on the eastbound side and exit 304 on the westbound side connect to PA 33 and US 209, which connect to Easton and Allentown towards the south. Exit 302 in both directions also serves PA 611 in Bartonsville. I-80 and US 209 are concurrent with each other through most of Stroudsburg and East Stroudsburg, between exits 304 and 309. Exits 303, 305, 306, and 307 serve downtown Stroudsburg and exit 308 serves downtown East Stroudsburg and the East Stroudsburg University of Pennsylvania. I-80 splits with US 209 at exit 309. Shortly after at exit 310 (the easternmost interchange in Pennsylvania), PA 611 intersects I-80 for the last time before starting its southerly route down the Delaware River, gradually moving away from I-80. I-80 continues east into the Delaware Water Gap, entering the state of New Jersey via the Delaware Water Gap Toll Bridge, with eastbound signage pointing towards New York City.
The corridor now served by I-80 was originally to be a branch of the Pennsylvania Turnpike from Sharon to Stroudsburg. Planning was shifted to the Pennsylvania Department of Highways in 1956 with the passage of the National Interstate and Defense Highways Act. 
In early plans for the Interstate Highway System, the connection across northern Pennsylvania would have paralleled U.S. Route 6N and U.S. Route 6 from what became Interstate 90 near West Springfield, Pennsylvania east to Scranton. (From Scranton east to Hartford, Connecticut, Interstate 84 was built parallel to US 6.) From Scranton a route went southeast along U.S. Route 611 to the Stroudsburg area, and then east along U.S. Route 46 to near New York City. On May 22, 1957, a request by Pennsylvania to move the corridor south was approved by the Federal Highway Administration.  (The Scranton-Stroudsburg connection was kept, and the new alignment merged with it west of Stroudsburg.) However, when the initial numbers were assigned later that year, they were drawn on a 1947 map, and so the corridor across northern Pennsylvania became part of Interstate 84, while the Scranton-New York route became Interstate 82. (I-80 ran along the Pennsylvania Turnpike to Harrisburg, where it split into I-80S to Philadelphia and I-80N to New York.)  This was corrected the next year, as the Keystone Shortway became part of I-80, the turnpike west of Harrisburg became I-80S (later I-76), and I-80N became I-78. I-84 was truncated to Scranton, and the Scranton-Stroudsburg connection became Interstate 81E (later renumbered Interstate 380). 
The first section of present I-80 to open was the Delaware Water Gap Toll Bridge, opened December 16, 1953. This had been built as part of U.S. Route 611 and connected back to its old alignment soon after crossing into Pennsylvania. Construction on the rest of I-80 began in 1959 and was completed in 1970. 
On March 7, 2011, the supporting wall on the eastbound I-80 bridge over Sullivan Trail in Tannersville collapsed from snow and rain. As a result, eastbound I-80 was reduced to one lane and Sullivan Trail was closed. 
On July 10, 2014, a criminal rock throwing incident known as the Interstate 80 rock throwing took place along I-80 in Union County, critically injuring and permanently disfiguring a passenger. Four local youths were responsible. 
In an effort to keep the Pennsylvania Turnpike system under public control, in June 2007, the Pennsylvania Turnpike Commission proposed tolling Interstate 80 as a means of raising transportation revenue. It seeked the permission to put tolls on the highway through a Federal Highway Administration pilot program that allowed three states to place tolls on interstates. Missouri and Virginia had already taken two of the spots.  Under the plan, the PTC would assume all maintenance and toll-taking operations on I-80. The plan called for up to ten toll plazas along the length of I-80 in Pennsylvania with a toll rate of 8 cents per mile (5.0 ¢/km), which would have been comparable to the rate on the Pennsylvania Turnpike following a projected toll increase.  Originally, I-80 was part of the PTC's 1,000 Mile Turnpike system, but with the passage of the Interstate Highway Act in 1956, the PTC abandoned the 1,000-mile (1,600 km) system and only maintained the original east–west Turnpike and its Northeastern Extension. Currently, the only toll on I-80 in Pennsylvania is the westbound toll at the Delaware Water Gap Toll Bridge between Pennsylvania and New Jersey.  Tolling on I-80 was to be completed by 2010.  On October 15, 2007, the lease for the Pennsylvania Turnpike Commission to toll I-80 was signed. 
This plan faced opposition from Northern Pennsylvania politicians who feared tolls would hurt the economy in the region  and who did not want their tolls going toward funding mass transit. Congressmen John E. Peterson and Phil English proposed a federal transportation bill that would ban the tolling of I-80. The chief executive officer of the Pennsylvania Turnpike Commission promised that the tolls would be used on highway projects in Pennsylvania and not on mass transit.  On December 12, 2007, the FHWA rejected the plan, and returned Pennsylvania's application for tolling I-80 with questions asking why the state should place tolls on the highway.
