Except at its northern end, I-79 is located on the Allegheny Plateau. Despite the somewhat rugged terrain, the road is relatively flat. Most of the highway is at an elevation of about {{convert|1000|to|1200|ft|m}} above sea level, with some lower areas near both ends and higher areas near Sutton, West Virginia. In the hillier areas, this flatness is achieved by curving around hills, along ridges, and in or partway up river valleys.United States Geological Survey topographic maps and aerial photos, accessed via Terraserver-USA From Sutton north, I-79 generally parallels the path of U.S. Route 19 (US 19).

{{expand section|date=April 2022}}

I-79 begins at a modified full Y interchange with I-77 along the northwest bank of the Elk River just northeast of Charleston. (Instead of the expected treatment of I-77 as the primary route at this interchange, the following traffic movements are found: northbound I-77 through traffic curves to the left, while traffic to northbound I-79 exits right; southbound I-77 through traffic curves to the right and merges on the right with traffic from southbound I-79, while traffic to northbound I-79 both exits and merges on the left; southbound I-79 traffic merges on the left with traffic from southbound I-77, while traffic to northbound I-77 both exits and merges on the left.) For its first {{convert|67|mi|km}} to a point just south of Flatwoods, I-79 is located in the watershed of the Elk River, which drains into the Kanawha River. It crosses the Elk River at Frametown and again at Sutton and never strays more than about {{convert|15|to|20|mi|km}} from it.National Atlas of the United States, [http://nationalatlas.gov/atlasftp.html#hucs00m Hydrologic Units (Watersheds) GIS data]{{webarchive|url=https://web.archive.org/web/20130504145622/http://www.nationalatlas.gov/atlasftp.html|date=May 4, 2013}}

I-79 enters Pennsylvania from Morgantown, West Virginia. South of Washington, it traverses mostly rural Greene County.

Between milemarkers 34 and 38, I-79 overlaps 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 I-376 while I-79 completely bypasses the city. Beyond the Pittsburgh area, I-79 traverses more rural areas in Butler, Lawrence, Mercer, Crawford, and Erie counties before arriving at its termination point in Erie. In Erie, I-90 connects from I-79 to Buffalo, New York, and the Canadian border.

Around milemarker 100 on the northbound side are two ghost ramps that were specifically built for the Boy Scouts of America in order to have access to Moraine State Park without having to travel on US 422 for the 1973 and 1977 National Scout Jamborees, which were held at Moraine. The ramps were permanently closed after the 1977 event but remain visible under encroaching vegetation.{{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}}{{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}}

The Pennsylvania General Assembly authorized the Pennsylvania Turnpike Commission to build two extensions in the 1950s. The Northwestern Extension, authorized in 1953, was to stretch from the main Pennsylvania Turnpike north to Erie and would have included a lateral connection between Ohio and New York, what was later built as I-90.Pennsylvania Turnpike Northwestern Extension Act, P.L. 706, No. 229, passed July 28, 1953 The Southwestern Extension, authorized in 1955, was to run south from the main line near Pittsburgh to West Virginia, where it connects with an extension of the West Virginia Turnpike.Pennsylvania Turnpike Southwestern Extension Act, P.L. 174, No. 52, passed June 14, 1955 Except for the section between Washington and Greater Pittsburgh, which was included as part of I-70,{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_August_14,_1957.jpg |title = Official Route Numbering for the National System of Interstate and Defense Highways, as adopted by the American Association of State Highway Officials |date = August 14, 1957 |scale = Scale not given |location = Washington, DC |publisher = Public Roads Administration |via = Wikimedia Commons }} the first portion of I-79 to be added to the plans was north from Pittsburgh to Erie, along the US 19 corridor.

On June 29, 1970, the swap of I-79 and I-279 was approved. At the same time, I-76 was extended west from Downtown Pittsburgh over former I-79 to the new location of I-79 west of Pittsburgh, so I-279 only ran north from Downtown Pittsburgh. On December 3, 1971, I-76 was rerouted to bypass Pittsburgh, and I-279 was extended to I-79 utilizing the former section of I-76.{{cite web |first = Richard |last = Weingroff |date = June 27, 2017 |publisher = Federal Highway Administration |url = https://www.fhwa.dot.gov/infrastructure/i76.cfm |work = Ask the Rambler |title = Was I-76 Numbered to Honor Philadelphia for Independence Day, 1776? }} The changes took effect on October 2, 1972.{{cite news |title = Interstates Renumbered |url = https://www.newspapers.com/clip/15491728/interstates_redone_10272_february/ |access-date = November 30, 2017 |work = The Pittsburgh Press |date = February 24, 1972 |page = 8 |via = Newspapers.com }}

On June 29, 1973, I-79 was extended from West Virginia exit 146 to exit 148 (I-68), where, at one point, traffic was forced onto the newly opened west end of Corridor E (now I-68) to exit 1.{{cite news |work = Charleston Daily Mail |title = 5 More Miles of I-79 Being Opened Today |date = June 29, 1973 }}{{page needed|date=March 2022}} A further extension of {{convert|6|mi|km|spell=in}}, including the Uffington Bridge over the Monongahela River southwest of Morgantown, was opened on August 30, 1973, leading north to exit 155 (Star City).{{cite news |work = Charleston Gazette |title = 6-Mile Stretch of I-79 Open |date = August 31, 1973 }}{{page needed|date=March 2022}}{{cite news |work = Charleston Gazette |date = September 5, 1973 }}{{page needed|date=March 2022}} This completed I-79 from north of Bridgeport to north of Morgantown.

Milepost based exit numbers were introduced to the Pennsylvania portion in 2001.

In 2000, construction began on the interchange with the Pennsylvania Turnpike in Cranberry. It was opened to traffic in 2004.

In late 2008, the missing ramps of the I-79/I-376 interchange (PA 60 was designated as the route for southbound traffic seeking to go to Pittsburgh International Airport and for airport traffic seeking to go northbound on I-79) were completed.{{cite web |url = http://www.post-gazette.com/local/neighborhoods/2008/08/02/Missing-links-take-shape-at-I-79-Parkway-West/stories/200808020112 |title = 'Missing links' take shape at I-79/Parkway West |work = Pittsburgh Post-Gazette }}

In June 2009, I-376 was extended west and north of Downtown Pittsburgh, and I-279 was truncated back to the section only running from Downtown Pittsburgh north to I-79.

During 2010, PennDOT undertook a $20.8 million improvement of I-79, Neville Island Bridge as well as other intersections.{{cite news|last=Schmitz|first=Jon|title=Neville Island Bridge project to bring closures, restrictions |url=http://www.post-gazette.com/stories/news/transportation/neville-island-bridge-project-to-bring-closures-restrictions-353997/|publisher=www.post-gazette.com|access-date=11 November 2012|date=18 August 2009}}

In 2010, construction began on improvements to exit 88. This was competed in December 2012.

Construction began in 2011 on improvements to the interchange with Interstate 70 in South Strabane. They were competed in Summer 2013.

In 2020, a new safety system went into effect to better warn motorists about the sharp curvature between the PA 60 interchange and PA 51 interchange.

Construction of the PA 576 interchange was completed on June 24, 2022.{{cite news|last=Blazina|first=Ed|title=Pennsylvania Turnpike finishes Southern Beltway, ready to begin Mon-Fayette Expressway|work=Pittsburgh Post-Gazette|date=June 19, 2022|url=https://www.post-gazette.com/news/transportation/2022/06/19/southern-beltway-mon-fayette-expressway-pennsylvania-turnpike/stories/202206160141|accessdate=June 19, 2022}}{{cite news|title=Southern Beltway fully opens Friday|publisher=KDKA-TV|location=Pittsburgh, PA|date=June 23, 2022|url=https://www.cbsnews.com/pittsburgh/news/full-southern-beltway-opens-friday/|access-date=June 27, 2022}} This involved construction of a new underpass.
