Interstate 79
Interstate 79 (I-79) is a north–south Interstate Highway in the eastern United States that spans the states of West Virginia and Pennsylvania, extending 343 miles (552 km) from its southern terminus at an interchange with Interstate 77 near Charleston, West Virginia, to its northern terminus at an interchange with Interstate 90, Pennsylvania Route 5, and Pennsylvania Route 290 in Erie, Pennsylvania.[1] In West Virginia, I-79 covers 160.52 miles (258.32 km) (as of 2014), functioning as a primary north–south corridor through the state's Appalachian region and serving key population centers including the capital city of Charleston in Kanawha County, Clarksburg in Harrison County, and Morgantown in Monongalia County before crossing into Pennsylvania near Mount Morris.[2] The route primarily follows a rural path with urban segments near major cities, facilitating freight transport of coal and natural gas resources vital to the regional economy while connecting to other interstates like I-64 and I-77.[2][3] In Pennsylvania, the highway extends 179.42 miles (288.79 km) northward from the West Virginia state line, passing through Washington and Allegheny counties en route to Pittsburgh, then continuing through Butler, Mercer, and Crawford counties to its end in Erie along the shore of Lake Erie.[4] Designated as the Raymond P. Shafer Highway in much of its Pennsylvania portion, I-79 serves as a critical link for commerce between the Pittsburgh metropolitan area and the Great Lakes ports, with significant traffic volumes supporting industrial and tourism activities; for instance, it carries over 5.3 million daily vehicle miles traveled (as of 2023) across its length in the state.[4] The route intersects major east–west interstates including I-70, I-376, I-80, and I-90, enhancing connectivity within the broader national highway network.[4]Overview
Route designation
Interstate 79 (I-79) was officially designated by the American Association of State Highway Officials (AASHO, now AASHTO) on November 12, 1958, as a north-south primary route within the Interstate Highway System, following the odd-numbering convention for north-south corridors established in the system's initial planning phase.[5] This designation aligned with the broader numbering scheme developed in 1957, which assigned one- and two-digit numbers to major transcontinental and regional routes to facilitate national connectivity.[6] As part of this system, I-79 serves as a key link in the eastern United States, emphasizing efficient north-south travel through Appalachian and Great Lakes regions. The route's southern terminus is located at an interchange with Interstate 77 (I-77) on the west side of Charleston, West Virginia, where I-79 begins its northward journey from the state's capital.[7] Its northern terminus is at an intersection with Pennsylvania Route 5 (PA 5, also known as Bayfront Parkway) and PA 290 in the city of Erie, Pennsylvania, providing access to Lake Erie's waterfront and nearby port facilities. These termini position I-79 as a connector between southern Appalachian gateways and northern industrial hubs, with the full route spanning two states. I-79 has a total designated length of 343.46 miles (552.75 km), comprising 160.52 miles (258.33 km) in West Virginia and 182.94 miles (294.42 km) in Pennsylvania, according to federal route logs.[8] The entire highway is designated as part of the National Highway System (NHS), a network of roadways critical to the nation's economy, defense, and mobility, as established by the National Highway System Designation Act of 1995. Along its path, I-79 intersects several other Interstate Highways, including I-77 at its southern end, I-68 near Morgantown, West Virginia, I-70 near Washington, Pennsylvania, I-376 in the Pittsburgh area, and I-90 just south of Erie, enhancing regional freight and passenger movement.Length and termini
Interstate 79 extends 343.46 miles (552.75 km) northward from its southern terminus at a junction with Interstate 77 near Charleston, West Virginia, to its northern terminus at an intersection with Pennsylvania Route 5, Pennsylvania Route 290, and Bayfront Parkway in Erie, Pennsylvania.[5] The route traverses 160.52 miles (258.33 km) in West Virginia, spanning from exit 0 at the southern end to exit 161 near the state line.[5][9] In Pennsylvania, it covers 182.94 miles (294.42 km), beginning at mile marker 0 just north of the state border and continuing to mile 182 at the northern end.[5][10] Along its path, Interstate 79 serves key urban centers such as Charleston and Morgantown in West Virginia, as well as Pittsburgh, Franklin, and Erie in Pennsylvania, facilitating regional travel and commerce in these areas.[5] The highway traverses the Allegheny Plateau and provides direct access to the Appalachian Mountains, while crossing the West Virginia-Pennsylvania border near Mount Morris, Pennsylvania. Economically, it connects coal and natural gas extraction regions in West Virginia to Great Lakes shipping ports in Erie, supporting resource transport and broader trade links.[11]Route description
West Virginia
Interstate 79 traverses 160.52 miles through West Virginia, beginning at a trumpet interchange with Interstate 77 on the northwest side of Charleston and proceeding north-northeasterly via the Jennings Randolph Expressway through rural and mountainous terrain, serving key communities including Clendenin, Sutton, Weston, Clarksburg, Fairmont, and Morgantown before reaching the Pennsylvania state line near Mount Morris. The route is entirely toll-free and features mile-based exit numbering starting from the southern terminus. Several interchanges provide access to universities and state parks, such as Exit 79 for Glenville State College and Exit 155 for West Virginia University.[12][13]Pennsylvania
Interstate 79 in Pennsylvania features exits numbered sequentially from 1 at the West Virginia state line in Perry Township, Greene County, northward to 183 at the terminus with PA 5 and PA 290 in Erie. The route includes 45 numbered interchanges over its 179.42-mile length through the state, with mile markers beginning at 0.00 along the border.[4] Notable junctions include the partial cloverleaf interchange with I-70 westbound near Washington at Exit 38, the turbine interchange with I-279 (the unsigned northern terminus of the auxiliary route) near Exit 73 in the Pittsburgh area, the complex stack interchange with I-80 at Exit 116A-B, and the trumpet interchange with I-90 at Exit 178A-B near Erie. Recent improvements to the Exit 147 interchange with US 6, US 19, and US 322 near Meadville, completed in phases including 2021 ramp and bridge enhancements by PennDOT, improved traffic flow and safety. Several urban-area exits, particularly around Pittsburgh, have truck restrictions to manage congestion and bridge weight limits, while some minor ramps remain unsigned.[14]History
Planning and establishment
The planning for Interstate 79 originated within the framework of the Interstate Highway System, authorized by the [Federal-Aid Highway Act of 1956](/page/Federal-Aid_Highway Act_of_1956), which established a national network of approximately 41,000 miles of limited-access highways to enhance interstate commerce and defense mobility across the United States. This legislation provided the federal funding and planning mandate that enabled states to propose specific routes, with the Bureau of Public Roads coordinating alignments to connect major economic regions.[15][16] On June 27, 1958, the American Association of State Highway Officials (AASHO) formally designated Interstate 79 as a key north-south corridor, initially from Erie, Pennsylvania, southward to Pittsburgh, with the route extending to Charleston, West Virginia, by the early 1960s to complete the full alignment. At designation, the planned length spanned about 318 miles, serving primarily to link the southern Appalachian coalfields with northern ports on the Great Lakes for efficient freight movement. This connection addressed post-World War II economic demands by facilitating the transport of coal and other resources from resource-rich areas in West Virginia and Pennsylvania to industrial centers and export facilities around Lake Erie.[5][5] The route's conceptualization emphasized regional economic integration, influenced by the need to upgrade outdated roadways like U.S. Route 19 through the rugged Appalachian terrain. In the Pittsburgh area, initial alignments were planned to traverse the city's west side along what would become the Parkway North (now Interstate 279), intentionally bypassing downtown congestion to prioritize through-traffic flow and minimize urban disruption. Debates during early planning focused on balancing challenging mountainous routes in West Virginia against flatter farmlands in Pennsylvania, ultimately favoring alignments that optimized connectivity while navigating topographic constraints.[5][17]Construction phases
Construction of Interstate 79 occurred in multiple phases across West Virginia and Pennsylvania from the early 1960s to the late 1970s, with segments opening as funding and engineering challenges were addressed. The project connected major urban centers like Charleston, Morgantown, Pittsburgh, and Erie, navigating challenging Appalachian terrain that included steep grades, bridges, and viaducts. Delays were common due to rugged landscapes in West Virginia's mountains and funding fluctuations under the Federal-Aid Highway Act, which provided 90% federal financing for the Interstate System.[18] In West Virginia, the first segment opened on December 21, 1967, between exits 125 (Saltwell Road) and 132 (South Fairmont), a 5-mile (8 km) stretch near Clarksburg, with construction later extending southward through more challenging terrain. By the late 1960s, work shifted to the mountainous sections between Clarksburg and Morgantown, built between 1968 and 1975; these included complex engineering feats such as tunnels and bridges to cross the Allegheny Plateau.[19][5] Pennsylvania's construction began in 1965 in the Pittsburgh area, extending the route from the state's southwestern border toward the north. The Parkway West extension, integrating I-79 with existing infrastructure like U.S. Route 22 and later I-376, was completed by 1970, opening key segments from Exit 60 near Imperial to Exit 78 in the Pittsburgh suburbs and providing direct access to the city's downtown via the I-279 spur. This phase involved building interchanges and bridges over the Monongahela River, costing millions in materials and labor amid urban development pressures.[10] The northern extension in Pennsylvania from Interstate 80 to Erie progressed in segments between 1968 and 1972, opening rural and semi-rural stretches through Mercer, Crawford, and Erie counties. Early openings included the section from Exit 141 (near Meadville) to Exit 147 in 1972, followed by connections to the Lake Erie waterfront; these phases focused on four-lane divided highway construction with minimal interchanges to serve agricultural and industrial areas. Overall, the entire I-79 project faced delays from mountainous terrain and funding shortfalls, reflecting the scale of earthwork, bridging, and pavement required across 343 miles.[10][20]Recent developments
In 1984, Interstate 79 was extended northward in Erie, Pennsylvania, by approximately one mile from its previous terminus at US 20 to a new end at PA 5 (Bayfront Parkway), marking the completion of the route's designated length.[10] This short segment connected the interstate directly to the Lake Erie waterfront, facilitating improved access to the Erie Bayfront area.[10] During the 1990s and 2000s, multiple widening projects enhanced capacity on I-79 in Pennsylvania near Pittsburgh to address congestion and support commercial traffic. In 1991, the section from I-376 to south of the Pennsylvania Turnpike was expanded from four to six lanes to better handle regional commuter and freight volumes.[10] Additional improvements in the early 2000s included truck climbing lanes in hilly terrains south of Pittsburgh and the integration of high-occupancy vehicle (HOV) facilities on connecting segments like I-279, which branch from I-79 and provide dedicated lanes for buses and carpools to alleviate urban bottlenecks.[21] These efforts were part of broader efforts to modernize the corridor for safer and more efficient travel.[22] In West Virginia, safety enhancements on the southern portions of I-79 after 2010 focused on reducing roadway departure incidents through targeted infrastructure upgrades. These included the installation of centerline and shoulder rumble strips along interstate segments to alert drivers veering from lanes, as well as reinforced guardrails and median barriers in vulnerable areas.[23] Such measures were implemented statewide under the Highway Safety Improvement Program, contributing to a decline in run-off-the-road crashes on high-speed routes like I-79.[24] The 2020s have seen significant investment in resilience and future-proofing along I-79. In Pennsylvania, ongoing bridge rehabilitation projects, including a $35 million rebuild of the I-70/I-79 interchange completed in 2014 but with continued maintenance, emphasize structural upgrades against weathering and traffic loads, with recent 2025 efforts addressing pavement and barrier repairs in Mercer County as part of federal-funded resiliency measures.[10][25] In West Virginia, the 2023 National Electric Vehicle Infrastructure (NEVI) plan identified I-79 as a priority Alternative Fuel Corridor, allocating funds for four 150 kW DC fast-charging ports at exits in Sutton and Weston, with Phase 1 construction planned for 2025 (as of late 2025, not yet underway).[26] Following the devastating 2016 floods in West Virginia, which caused closures and damage to sections of I-79 near Elkview and Clendenin due to washed-out access roads and high water, repair efforts prioritized rapid restoration and flood mitigation without necessitating major reroutings.[27] By 2023, nearly all flood-related infrastructure recoveries were complete, including reinforced pavements and drainage improvements, ensuring the route's operational continuity as of 2025.[28] In August 2025, a widening project near Fairmont in Marion County was completed, expanding a 3-mile (4.8 km) section to six lanes to accommodate increased traffic.[29]Exit list
