The Mon–Fayette Expressway is a Fayette and Washington counties, serving as an alternative to Interstate 79 to the west, as well as relieving the PA 51 alignment from Pittsburgh to Uniontown. In addition, a second branch in Allegheny County will provide a bypass to the Squirrel Hill Tunnel.

Although it is being built to Interstate Highway standards, there is debate as to whether or not the freeway will become part of the Interstate Highway System. At least one proposal was to give it the Interstate 97 designation (unrelated to the existing I-97 in Maryland), while others have been to make it a spur route of I-68.[1] In the interim, the highway uses state highway designations instead, as it does not parallel an existing U.S. Route for its entire length, though it does parallel and at times run concurrent with U.S. Route 40 and U.S. Route 119 for portions of its length. The route, in its three jurisdictions, uses the number 43 for familiarity-based reasons, and is thusly known as West Virginia Route 43, Pennsylvania Route 43, and PA Turnpike 43. Most of the route is maintained by the Pennsylvania Turnpike Commission, while the Pennsylvania Department of Transportation maintains small portions of the highway near Uniontown, and the West Virginia Division of Highways maintains the short section in West Virginia. Despite the numerous agencies overseeing the highway, it is one continuous highway. South of Jefferson Hills, the Mon–Fayette Expressway is complete. Construction on the final 24-mile (39 km) stretch that will connect the highway's current northern terminus at Jefferson Hills to Pittsburgh and Monroeville is pending due to funding limitations.[2]

In order to provide access to certain interchanges within the Uniontown-to-Brownsville project, the PTC had to build several toll-free connectors, the most notable of which extended a four-lane section of U.S. Route 40 near Brownsville, eliminating a forty-year-old freeway stub in the process. Near Uniontown, the PTC constructed a four-lane road, named Northgate Highway, between U.S. Route 40 and Pennsylvania Route 51. In addition, a new connector was added to join Telegraph Road and Bull Run Road in Luzerne Township, potentially opening many acres of land to future development. The aforementioned access roads were necessary to provide access to exits 22, 15, and 26 respectively, but these routes were also designed to improve local connections and accommodate any future economic development in the interchanges' immediate vicinity.

In the 1990s, the Mon–Fayette Expressway project was expanded to include another highway, the Southern Beltway. The Southern Beltway is planned to be a high-speed east-west link between the Mon–Fayette Expressway, Interstate 79, U.S. Route 22, Interstate 376, and Pittsburgh International Airport. A 6-mile (9.7 km) section of the beltway between Pittsburgh International Airport/Interstate 376 and U.S. Route 22 opened to traffic in 2006.[27] The new road has been designated as Pennsylvania Route 576. A 13-mile (21 km) section between U.S. 22 and I-79 is expected to be open by 2019, with the third section being between I-79 and a section of the Mon–Fayette Expressway near Finleyville, Pennsylvania just south of the current northern terminus.[12][13]

Exit list

In West Virginia, legislators have flip-flopped a few times regarding whether their section will be a toll road. When tolls were first proposed, West Virginia had planned to work with the Pennsylvania Turnpike Commission to collect tolls at the existing Pennsylvania mainline plaza, but this plan was not accepted by the West Virginia Legislature. Instead, West Virginia planned to construct a toll plaza north of Goodwin Hill Road.[24][25] West Virginia officials also contemplated whether to use all-electronic tolling or a more traditional tolling scheme. In the end, tolling plans were scrapped by West Virginia's legislature. Rejection resulted from concerns related to camera enforcement, billing, and operational costs. However, West Virginia reserves the right to levy tolls in the future if these issues are settled.[26]

The Mon–Fayette Expressway has four mainline toll barriers located in Fairchance, Redstone, California, and Jefferson Hills. As of 2014, the Fairchance and California barriers charge $1.60 using cash and $1.04 using E-ZPass for passenger vehicles while the Redstone and Jefferson Hills barriers charge $2.05 using cash and $1.39 using E-ZPass for passenger vehicles. There are also ramp toll plazas at the northbound exit and southbound entrances at exit 4, 15, and 18, the southbound exit and northbound entrance at exits 22 and 26, and the northbound exit and southbound entrance at exits 39, 44, and 48. The ramp tolls cost $1.15 using cash and $0.69 using E-ZPass for passenger vehicles.[23]

The Mon–Fayette Expressway is a toll road for much of its length. Unlike the Pennsylvania Turnpike mainline and the Northeast Extension, which uses long-distance tickets, the Mon–Fayette Expressway collects fixed tolls at regular intervals. In addition, auxiliary toll plazas exist on certain on- and off-ramps. In 2008, the PTC retrofitted all toll plazas to accept E-ZPass, and Express E-ZPass lanes are available at the newer toll plazas.[22]


During the morning of August 6, 2013, a 1946 Universal Stinson, in which two people were flying, landed on the expressway near Centerville, Pennsylvania after encountering propeller problems. The plane had taken off from the Rostraver Airport and was heading toward Waynesburg, Pennsylvania and had reached an altitude of 3,000 ft. After landing, the plane passed several cars on the highway before pulling off to the side of an on-ramp.[20] The pilot, a local teacher from Brownsville Area School District, was later fined nearly $3,000 by the PTC in addition to paying $1,000 in towing costs.[21]

2013 plane landing

In May 2013, a raise in the oil tax cap in Pennsylvania was proposed in the Pennsylvania General Assembly to fund additional transportation projects, including completing the Mon–Fayette Expressway and the Southern Beltway, as part of a larger transportation bill to help fund projects in the state.[15] Pennsylvania Governor Tom Corbett signed a modified version of the bill into law, known as Act 89, on November 25, 2013 after much debate in the General Assembly that nearly killed the bill before being passed.[16] Act 89, which local politicians acknowledged that without passage would've killed the remaining segments of the Mon–Fayette Expressway, is expected to provide funding to complete the Southern Beltway all the way to the Mon–Fayette Expressway and provide a little less than half of the $2.2 billion (as of December 2013) needed to complete the Mon–Fayette Expressway, as well as the option for P3 funding.[17][18] It was also acknowledged that like the Uniontown-to-Brownsville Project, the final leg may be built in multiple phases in order to preserve funding for other projects in the state. It is expected that even with the new funding that one of the two legs of the Mon–Fayette Expressway will not be built and the highway will now be built either to Pittsburgh or Monroeville instead of both.[17] The second leg of the Southern Beltway, which had already been announced will proceed in construction, will be the first portion of the two highways that will be built with the new funding available,[15] with a planned opening to I-79 in 2019.[19]

In July 2013, the Allegheny County portion of the expressway was the subject again of news articles indicating that a change in approach may be taken. This revised approach would allow for completion of the expressway to Monroeville. The spur to Pittsburgh would not be constructed but rather the East Busway would be extended to Monroeville to allow for Park-and-Ride into Downtown Pittsburgh. Another option currently being considered is to open the Busway to High Occupancy Vehicle (HOV) traffic.[14]

After environmental clearances were obtained and right-of-way acquisition had begun, the project was placed on-hold due to lack of funding. Current estimates for this section are in the neighborhood of $3.6 billion and funding has not been identified. A public-private partnership was explored but nothing feasible resulted. It is unlikely that any new construction will commence in the near future unless a new tax is imposed or private funding identified,[11] although funding was secured for the section of Pennsylvania Route 576 in between Interstate 79 and its current eastern terminus at U.S. Route 22, bringing hope on an eventual completion of the Mon–Fayette Expressway.[12][13]

After a review of several alternative alignments designated by colors (Green, Yellow, Orange, and Blue), a series of public meetings hosted by the Pennsylvania Turnpike Commission sought feedback from residents likely effected by the expressway's construction. The preferred route was identified as running parallel to PA Route 837 through the neighborhoods of Clairton, Duquesne, crossing over the Monongahela River near Kennywood Park, and then continuing along the northern side of the river through Braddock, Rankin, and Glen Hazel, finally connecting to I-376 at Oakland. A western-spur would be located near the crossing and continue north through Turtle Creek and Monroeville to I-376 in Wilkins. The addition of the spur allowing for an alternative to I-376 that would by-pass the often congested Squirrel Hill Tunnel.

As of November 13, 2012, the final and most controversial segment of the Mon-Valley Expressway Project, the connection between Jefferson Hills and I-376, is in limbo.[2]

Allegheny County

In West Virginia, construction commenced in 2000 but progressed slowly due to limited funding. By the end of 2003, only the Rubles Run Bridge and two pieces of highway totaling little more than 2.5 miles (4.0 km) were completed. Over the next few years, construction inched ahead. By 2009, the Morgan Run Bridge was finished, and local roads near Cheat Lake were re-built to accommodate the expressway. The final contracts to build the Cheat Lake and Interstate 68 interchanges were respectively awarded in December 2008 and July 2009, partly as a result of an ARRA fund infusion.[8][9] On July 11, 2011, officials in West Virginia opened their 4-mile (6.4 km) section of the Mon–Fayette Expressway. Likewise, the PTC opened the southernmost 1.7 miles (2.7 km) in Pennsylvania, which sat unused for over a decade. Noteworthy features on the West Virginia section include two high-level bridges, along with the I-68 interchange, which is a hybrid design that utilizes both high-speed ramps and at-grade intersections. A second phase for this interchange is planned, but that project will not be undertaken until traffic volumes merit.[10] If the second phase is built, the I-68 interchange will be upgraded to a directional T.

West Virginia 43

In 2006, construction began on a 17-mile (27 km) stretch connecting the oldest section of the expressway near Fredericktown to the northern terminus of the Chadville Demonstration Project. Known locally as the "Uniontown-to-Brownsville Project," limited funding necessitated a two-phased approach to completion. The first phase involved construction of an 8-mile (13 km) section of expressway running parallel to a hazardous stretch of U.S. Route 40 between Brownsville and Uniontown. Phase 1 opened on October 23, 2008.[2] The second phase consisted of a 9-mile (14 km) section that connects first phase of this project to the oldest portion of the expressway near Fredericktown, as well as the Mon–Fayette Expressway Bridge crossing the Monongahela River. Additionally, the second phase includes a directional T interchange at U.S. Route 119 in Uniontown. On December 13, 2010, the U.S. 119 interchange opened to traffic, and the remainder of Phase 2 opened with a soft launch on July 16, 2012. A formal ribbon-cutting ceremony was held on August 2, 2012. Completion of Phase 2 brought an uninterrupted 58-mile (93 km) stretch of highway between I-68 and the current northern terminus at Pennsylvania Route 51 in Jefferson Hills, Pennsylvania.


Named formally for the PA State Senator who pushed to expand the state's highway system, the J. Barry Stout Expressway segment connects Interstate 70 with Route 51. Construction began in 1995 and the entire segment from Interstate 70 to Route 51 was open by April 12, 2002.[2] The Joe Montana Bridge, named after the Pro Football Hall of Fame quarterback who grew up in the immediate area in nearby Monongahela, Pennsylvania,[7] is located along the route.

J. Barry Stout Expressway

In the early 1990s, the Pennsylvania State Legislature passed a bill that hypothecated a portion of the state’s fuel excise revenue to the PTC. This new revenue stream initially provided the funding to complete an 8-mile (13 km) section from the southern terminus of the Chadville Demonstration Project to the West Virginia state line as well as a 17-mile (27 km) section from the Interstate 70 interchange to Pennsylvania Route 51 in Jefferson Hills. On March 1, 2000, most of the section between the Chadville Demonstration Project and the West Virginia state line opened to traffic.[2]

In 1985, the Mon–Fayette Expressway project was transferred to the Pennsylvania Turnpike Commission (PTC) under Act 61 legislation.[2] While PennDOT assessed preliminary engineering and right-of-way options in the 1970s and early 1980s, the PTC accelerated design work and began unveiling detailed plans in earnest by the late 1980s.[2] Funding appropriated through the PTC allowed construction to resume in 1988, and on October 12, 1990, the entire stretch from U.S. Route 40 to Interstate 70 opened to traffic.[2] Initially, the PTC did not have adequate funding to construct new sections, but Representative Austin Murphy secured congressional funds that directed PennDOT to build a 4-mile (6.4 km) stretch of the expressway south of Uniontown.[2] Aside from being part of a larger project, the new segment was designed to provide high speed access between the Uniontown bypass, Fairchance, and a new business park. This section, dubbed the Chadville Demonstration Project, opened in November 1992.

Chadville Demonstration Project

Limited funding caused the project to be placed on hiatus in the early 1980s. During this time, the coke and steel industry that originally inspired the route experienced an economic downturn and near collapse. Rather than cancel the project, local leaders touted it as a means of stimulating the distressed economy; providing a link from the City of Pittsburgh to West Virginia along which manufacturing facilities and other industry could be located. The project was redesignated as the Mon–Fayette Expressway, a portmanteau of Monongahela River Valley and Fayette County, two of the areas the new road would connect. The project was designed to be completed in phases with the most controversial segment, PA 51 to Pittsburgh, scheduled to be completed last.

The Mon–Fayette Expressway was originally proposed in the 1950s as a way to link the coke- and steel-producing towns situated in the Monongahela River Valley, thus providing a supplement to existing rail and river passages. Running along the existing PA Route 48, the highway was initially referred to as “New 48” and right-of-way clearance began in the early 1970s. PennDOT initiated construction in 1973, and the first segment opened in 1977.[2] This segment consisted of a partial cloverleaf interchange at U.S. Route 40 and a 2-mile (3.2 km) stretch of four-lane highway that spurred south of the new interchange toward Fredericktown. Despite severe financial constraints, PennDOT built the remainder of the ramps at the U.S. 40 cloverleaf along with a separate 2-mile (3.2 km) stretch of highway near California in the early 1980s.[2]

Early history


[6][3], where it continues through more rural areas. The toll road reaches the Jefferson Hills mainline toll plaza and continues northeast, with the median widening and the road narrowing to one lane in each direction as it comes to a bridge over PA 51. The Mon–Fayette Expressway continues a short distance to its current northern terminus, where the traffic lanes turn west as Jefferson Boulevard and head to PA 51.Allegheny County in Jefferson Hills The tollway enters [5][3] and continues north through wooded areas with some fields and mines. Farther north, the highway comes to a diamond interchange serving Finleyville-Elrama Road. Past this interchange, Toll PA 43 curves to the northeast.Union Township into Mingo Creek Viaduct exit. The Mon–Fayette Expressway crosses the PA 136 and makes a sharp curve to the west, continuing through more rural areas. The tollway curves north again near a mine and comes to the Carroll Township to the east. Toll PA 43 heads into Donora and CharleroiPast this interchange, the toll road winds north through more woodland and reaches a diamond interchange at Coyle Curtain Road, which provides access to the communities of
PA 136 exit sign

The Mon–Fayette Expressway crosses the Monongahela River on the Mon–Fayette Expressway Bridge into Centerville in Washington County, where it curves north and comes to an interchange with PA 88. At this point, PA 88 joins Toll PA 43 for a concurrency on the freeway, with the road heading northeast through forested areas. The highway comes to a cloverleaf interchange with US 40, at which point PA 88 splits to the east to follow US 40 and Toll PA 43 continues northeast on the Mon–Fayette Expressway, entering California. The road continues through fields and woods, reaching an interchange with Malden Road that provides access to PA 88 Truck. The tollway continues north through dense woodland, bypassing the center of California to the west. The median widens as the highway comes to the exit for Elco Hill Road. After this, the median narrows again as Toll PA 43 curves northwest and comes to the California mainline toll plaza. A short distance later, the Mon–Fayette Expressway enters Fallowfield Township and comes to a cloverleaf interchange serving I-70.[3][5]

At this point, the Mon–Fayette Expressway again becomes a toll road maintained by the PTC and signed as Toll PA 43, heading northwest through rural areas with some nearby development. The highway reaches a diamond interchange with Old Pittsburgh Road which provides connections to US 40 and PA 51. Past this interchange, the tollway crosses into Menallen Township and runs through a mix of farmland and woodland. Farther northwest, Toll PA 43 comes to an interchange at Keisterville-Upper Middletown Road, which provides access to US 40 to the southwest. The Mon–Fayette Expressway enters Redstone Township, where it reaches the Redstone mainline toll plaza. The highway continues northwest through rural land and comes to a diamond interchange with US 40. Following this, the toll road heads northwest through rural areas to the south of Brownsville, crossing the Dunlap Creek into Luzerne Township. Here, Toll PA 43 reaches the Telegraph Road exit and curves to the northwest.[3][4]

At this point, the Mon–Fayette Expressway becomes toll-free and maintained by the Pennsylvania Department of Transportation (PennDOT), signed as PA 43. The roadway continues through farmland and woodland as it bypasses Fairchance to the west. Farther north, PA 43 comes to an interchange with US 119 and the northern terminus of PA 857, at which point US 119 forms a concurrency with PA 43 on the freeway, with the PA 43 designation becoming unsigned. A short distance later, US 119/PA 43 crosses into South Union Township and reaches an interchange with the US 40 freeway, at which point US 40 merges with US 119 and PA 43. The three routes bypass Uniontown to the west on the freeway, running between farmland and woods to the west and residential neighborhoods to the east. The highway comes to a diamond interchange with Walnut Hill Road, where it curves northwest and passes near more homes. US 40/US 119/PA 43 curves northeast and reaches a trumpet interchange providing access to PA 21 in a commercial area. A short distance later, the freeway comes to an interchange with the western terminus of US 40 Bus., at which point US 40 splits to the northwest. US 119 and PA 43 continue northeast on the freeway into North Union Township, where it runs between rural areas to the northwest and residential areas to the southeast. PA 43 splits from US 119 at an interchange that also serves PA 51.[3][4]
