[[File:2022-05-14 11 27 49 View north along Interstate 79 just north of Exit 7 in Whiteley Township, Greene County, Pennsylvania.jpg|thumb|left|I-79 northbound past exit&nbsp;7 in [[Whiteley Township, Pennsylvania]]]]
I-79 enters [[Pennsylvania]] from [[Morgantown, West Virginia]]. South of [[Washington, Pennsylvania|Washington]], it traverses mostly rural [[Greene County, Pennsylvania|Greene County]].

Between milemarkers&nbsp;34 and 38, I-79 [[concurrency (road)|overlaps]] [[Interstate 70|I-70]] in the Washington area before heading north toward [[Pittsburgh]].

I-79 is carried over the [[Ohio River]] by the [[Neville Island Bridge]], approximately {{convert|8|mi|km|spell=in}} northwest of Pittsburgh.

The freeway into Pittsburgh requires drivers to use [[Interstate 376|I-376]] while I-79 completely bypasses the city. Beyond the Pittsburgh area, I-79 traverses more rural areas in [[Butler County, Pennsylvania|Butler]], [[Lawrence County, Pennsylvania|Lawrence]], [[Mercer County, Pennsylvania|Mercer]], [[Crawford County, Pennsylvania|Crawford]], and [[Erie County, Pennsylvania|Erie]] counties before arriving at its termination point in [[Erie, Pennsylvania|Erie]]. In Erie, [[Interstate 90|I-90]] connects from I-79 to [[Buffalo, New York]], and the Canadian border.

Around milemarker&nbsp;100 on the northbound side are two [[ghost ramp]]s that were specifically built for the [[Boy Scouts of America]] in order to have access to [[Moraine State Park]] without having to travel on [[U.S. Route&nbsp;422|US&nbsp;422]] for the [[1973 National Scout Jamboree|1973]] and [[1977 National Scout Jamboree|1977]] National Scout Jamborees, which were held at Moraine. The ramps were permanently closed after the 1977 event but remain visible under encroaching vegetation.<ref>{{cite web |url = http://www.gribblenation.com/papics/ghostramps/ramps.html |title = Ghost Ramps |website = Gribblenation.com |date = June 5, 2005 |access-date = August 8, 2017 }}{{sps|certain=yes|date=March 2022}}</ref><ref>{{Google maps|url=https://maps.google.com/maps?q=40.972705,-80.132024&hl=en&sll=41.068419,-80.057381&sspn=0.036691,0.077162&t=h&z=16 |title=Ghost ramps around the 100 mile marker |access-date=August 8, 2017}}</ref>
