The '''Mon–Fayette Expressway''' is a partially-completed [[controlled-access highway|controlled-access]] [[toll road]] that is planned to eventually link [[Interstate 68]] near [[Morgantown, West Virginia|Morgantown]], [[West Virginia]] with [[Interstate 376]] near [[Monroeville, Pennsylvania]]. The ultimate goal of the highway is to provide a high speed north–south connection between Morgantown and the eastern side of [[Pittsburgh]] while revitalizing economically distressed [[Monongahela River]] Valley towns in [[Fayette County, Pennsylvania|Fayette]] and [[Washington County, Pennsylvania|Washington]] counties, serving as an alternative to [[Interstate 79]] to the west, as well as relieving the PA 51 alignment from Pittsburgh to Uniontown.

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''' ('''I-97''') designation (unrelated to the [[Interstate 97|existing I-97 in Maryland]]), while others have been to make it a spur route of I-68.<ref>{{cite news |title= Expressway Link in Fayette Gets Year Delay |work= [[Pittsburgh Tribune-Review]] |first= S.K. |last= Musisko |date= March 2, 1998 <!--|access-date= February 5, 2014-->}}</ref> In the interim, the highway uses [[state highway]] designations instead, as it does not parallel an existing [[United States Numbered Highways|U.S. Route]] for its entire length, though it does parallel and at times run [[Concurrency (road)|concurrent]] with [[U.S. Route 40 in Pennsylvania|U.S. Route 40]] and [[U.S. Route 119 in Pennsylvania|U.S. Route 119]] for portions of its length. The route, in its three jurisdictions, uses the number 43 for familiarity, and is thus known as '''West Virginia Route&nbsp;43''' ('''WV&nbsp;43'''), '''Pennsylvania Route&nbsp;43''' ('''PA&nbsp;43'''), and '''PA Turnpike&nbsp;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, Pennsylvania|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, Pennsylvania|Jefferson Hills]], the Mon–Fayette Expressway is complete. Construction to complete the highway to Duquesne began on May 22, 2023,<ref name=KDKA>{{Cite web|url=https://www.cbsnews.com/pittsburgh/news/mon-fayette-expressway-groundbreaking/|title=Officials break ground on next phase of Mon/Fayette Expressway|date=May 22, 2023|publisher=CBS News |access-date = May 22, 2023}}</ref> with plans existing to extend the road further to Monroeville.

The Mon–Fayette Expressway begins at a [[diamond interchange]] with [[Interstate 68|I-68]] in [[Cheat Lake, West Virginia|Cheat Lake]] in [[Monongalia County, West Virginia|Monongalia County]], [[West Virginia]], heading north as a four-lane freeway signed as WV&nbsp;43. The highway passes near some residential development and comes to an interchange with Bowers Lane that provides access to County Route 857. Following this, WV&nbsp;43 curves northeast and runs through forested areas, turning to the north.<ref name=gm>{{google maps |url= https://www.google.com/maps?saddr=WV-43+N&daddr=Unknown+road&hl=en&sll=40.293439,-79.908779&sspn=0.009067,0.021136&geocode=FXxUXQId0JA9-w;FfLeZgIdlqI8-w&t=h&mra=ls&z=9 |title= Overview of Mon–Fayette Expressway |access-date= May 20, 2014}}</ref>

The Mon–Fayette Expressway crosses the state line into [[Pennsylvania]], where it becomes PA&nbsp;Turnpike&nbsp;43, which is maintained by the [[Pennsylvania Turnpike Commission]] (PTC). The freeway heads through [[Springhill Township, Fayette County, Pennsylvania|Springhill Township]] in [[Fayette County, Pennsylvania|Fayette County]], passing through forested areas with some fields. The first interchange in the state is at Gans Road, which provides access to [[U.S. Route 119 in Pennsylvania|US&nbsp;119]] to the west and [[Pennsylvania Route 857|PA&nbsp;857]] to the east.

Here, PA&nbsp;Turnpike&nbsp;43 becomes a [[toll road]] and continues northeast through more rural areas, where it crosses into [[Georges Township, Fayette County, Pennsylvania|Georges Township]] and comes to a diamond interchange with Rubles Mill Road that accesses PA&nbsp;857 a short distance to the east. Past this interchange, the highway comes to the Fairchance mainline toll plaza before it curves north and then northwest. The route passes to the west of an industrial park before reaching an interchange with Big Six Road which provides access to US&nbsp;119 and PA&nbsp;857.<ref name=gm/><ref name=PennDOTFayette>{{Cite FTP |author= [[Pennsylvania Department of Transportation]] Geographic Information Division |title= General Highway Map Fayette County |url= ftp://ftp.dot.state.pa.us/public/pdf/BPR_pdf_files/Maps/GHS/Roadnames/fayette_GHSN.PDF |year= 2013 |scale= 1:65,000 |location= Harrisburg |server= Pennsylvania Department of Transportation |url-status= dead |access-date= May 20, 2014 }}</ref>

At this point, the Mon–Fayette Expressway becomes toll-free and maintained by the [[Pennsylvania Department of Transportation]] (PennDOT), signed as PA&nbsp;43. The roadway continues through farmland and woodland as it bypasses [[Fairchance, Pennsylvania|Fairchance]] to the west. Farther north, PA&nbsp;43 comes to an interchange with US&nbsp;119 and the northern terminus of PA&nbsp;857, at which point the road becomes US&nbsp;119. PA&nbsp;43 continues as an unsigned [[concurrency (road)|concurrency]] with US&nbsp;119 for {{convert|4|mi|km}} around [[Uniontown, Pennsylvania|Uniontown]], with a sign saying that PA&nbsp;43 traffic should follow signs for US&nbsp;119 through Uniontown. A short distance later, US&nbsp;119 and the unsigned PA&nbsp;43 cross together into [[South Union Township, Pennsylvania|South Union Township]] and reach an interchange with the [[U.S. Route 40 in Pennsylvania|US&nbsp;40]] freeway, at which point US&nbsp;40 merges with US&nbsp;119 and the unsigned PA&nbsp;43, joining the concurrency. 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&nbsp;40/US&nbsp;119/unsigned&nbsp;PA&nbsp;43 curves northeast and reaches a [[trumpet interchange]] providing access to [[Pennsylvania Route 21|PA&nbsp;21]] in a commercial area. A short distance later, the freeway comes to an interchange with the western terminus of [[U.S. Route 40 Business (Uniontown, Pennsylvania)|US&nbsp;40 Business]], at which point US&nbsp;40 splits to the northwest. US&nbsp;119 and the unsigned PA&nbsp;43 continue northeast on the freeway into [[North Union Township, Fayette County, Pennsylvania|North Union Township]], where they run between rural areas to the northwest and residential areas to the southeast. The unsigned concurrency ends as PA&nbsp;Turnpike&nbsp;43, again a toll road maintained by the PTC, splits from US&nbsp;119 at an interchange that also serves [[Pennsylvania Route 51|PA&nbsp;51]].<ref name=gm/><ref name=PennDOTFayette/>

The Expressway heads northwest through rural areas with some nearby development. The highway reaches a diamond interchange with Old Pittsburgh Road which provides connections to US&nbsp;40 and PA&nbsp;51. Past this interchange, the tollway crosses into [[Menallen Township, Fayette County, Pennsylvania|Menallen Township]] and runs through a mix of farmland and woodland. Farther northwest, PA&nbsp;Turnpike&nbsp;43 comes to an interchange at Keisterville-Upper Middletown Road, which provides access to US&nbsp;40 to the southwest. The Mon–Fayette Expressway enters [[Redstone Township, Pennsylvania|Redstone Township]], where it reaches the Redstone mainline toll gantry. The highway continues northwest through rural land and comes to a diamond interchange with US&nbsp;40. Following this, the toll road heads northwest through rural areas to the south of [[Brownsville, Pennsylvania|Brownsville]], crossing the Dunlap Creek into [[Luzerne Township, Pennsylvania|Luzerne Township]]. Here, PA&nbsp;Turnpike&nbsp;43 reaches the Telegraph Road exit and curves to the northwest.<ref name=gm/><ref name=PennDOTFayette/>

The Mon–Fayette Expressway crosses the [[Monongahela River]] on the [[Mon–Fayette Expressway Bridge]] into [[Centerville, Washington County, Pennsylvania|Centerville]] in [[Washington County, Pennsylvania|Washington County]], where it curves north and comes to an interchange with [[Pennsylvania Route 88|PA&nbsp;88]]. At this point, the road becomes toll-free again, though still owned by the PTC and signed PA&nbsp;Turnpike&nbsp;43. PA&nbsp;88 also joins the freeway for a short concurrency, with the road heading northeast through forested areas. The highway comes to a [[cloverleaf interchange]] with US&nbsp;40, at which point&nbsp;PA 88 splits to the east to follow US&nbsp;40 and PA&nbsp;Turnpike&nbsp;43 continues northeast on the Mon–Fayette Expressway, entering [[California, Pennsylvania|California]]. The road continues through fields and woods, reaching an interchange with Malden Road that provides access to [[Pennsylvania Route 88 Truck|PA&nbsp;88&nbsp;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 which it once again becomes a toll road. The median narrows again as PA&nbsp;Turnpike&nbsp;43 curves northwest and comes to the California mainline toll plaza. A short distance later, the Mon–Fayette Expressway enters [[Fallowfield Township, Washington County, Pennsylvania|Fallowfield Township]] and comes to a cloverleaf interchange serving [[Interstate 70 in Pennsylvania|I-70]].<ref name=gm/><ref name=PennDOTWashington>{{Cite FTP |author= Pennsylvania Department of Transportation Geographic Information Division |title= General Highway Map Washington County |url= ftp://ftp.dot.state.pa.us/public/pdf/BPR_pdf_files/Maps/GHS/Roadnames/washington_GHSN.PDF |year= 2013 |scale= 1:65,000 |location= Harrisburg |server= Pennsylvania Department of Transportation |url-status= dead |access-date= May 20, 2014 }}</ref>

[[File:PA Route 43 exit 44.jpg|thumb|right|PA&nbsp;136 exit sign along PA Turnpike 43 in Carroll Township]]Past 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 [[Charleroi, Pennsylvania|Charleroi]] and [[Donora, Pennsylvania|Donora]] to the east. PA&nbsp;Turnpike&nbsp;43 heads into [[Carroll Township, Washington County, Pennsylvania|Carroll Township]] 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 [[Pennsylvania Route 136|PA&nbsp;136]] exit. The Mon–Fayette Expressway crosses the [[Mingo Creek Viaduct]] into [[Union Township, Washington County, Pennsylvania|Union Township]] and continues north through wooded areas with some fields and mines.

==Tolls==
The Mon–Fayette Expressway is a toll road for most of its length, and utilizes [[all-electronic tolling]] using [[toll-by-plate]] (which uses [[automatic license plate recognition]] to take a photo of the vehicle's license plate and mail a bill to the vehicle owner) or [[E-ZPass]]. 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.<ref>{{cite press release |author= Pennsylvania Turnpike Commission |url= http://readme.readmedia.com/Express-E-ZPass-Lanes-to-Open-June-8-on-Mon-Fayette-Expressway/1356419 |title= Express E-ZPass Lanes to Open June 8 on Mon–Fayette Expressway |publisher= [[Pennsylvania Turnpike Commission]] |date= June 4, 2010 |access-date= June 25, 2011}}</ref>

The Mon–Fayette Expressway has four mainline toll barriers located in Fairchance, Redstone, California, and Jefferson Hills. {{As of|2024}}, the Fairchance and California barriers charge $4.70 using toll-by-plate and $1.90 using E-ZPass for passenger vehicles while the Redstone and Jefferson Hills barriers charge $5.60 using toll-by-plate and $2.90 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 $3.40 using toll-by-plate and $1.50 using E-ZPass for passenger vehicles.<ref name="ptctolls">{{cite book|url=https://files.paturnpike.com/production/docs/default-source/resources/tolls/toll-schedule-2023/tollschedule_2024_tolls.pdf|title=2024 Toll Schedule|publisher=Pennsylvania Turnpike Commission|year=2024|access-date=January 7, 2024}}</ref>

All-electronic tolling was planned to be implemented on the Mon–Fayette Expressway, along with the remainder of the Pennsylvania Turnpike system, in the later part of 2021.<ref>{{cite news|last=Blazina|first=Ed|title=Pa.

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.<ref name="Open Spring 2011">{{cite news |last= Beard |first= David |title= Expressway to Open in Spring 2011 |url= http://ee.dominionpost.com/Olive/ODE/DominionPost/LandingPage/LandingPage.aspx?href=RFBvc3QvMjAxMC8wNi8yNA..&pageno=MQ..&entity=QXIwMDEwMw..&view=ZW50aXR5 |archive-url= https://archive.today/20130121194011/http://ee.dominionpost.com/Olive/ODE/DominionPost/LandingPage/LandingPage.aspx?href=RFBvc3QvMjAxMC8wNi8yNA..&pageno=MQ..&entity=QXIwMDEwMw..&view=ZW50aXR5 |url-status= dead |archive-date= January 21, 2013 |access-date= June 24, 2010 |work= The Dominion Post |location= Morgantown, WV |date= June 24, 2010}}</ref><ref name="Opens November">{{cite news |title= Traffic May Move in November on Road |url= http://ee.dominionpost.com/Olive/ODE/DominionPost/LandingPage/LandingPage.aspx?href=RFBvc3QvMjAxMC8wOS8xNg..&pageno=Nw..&entity=QXIwMDcwNA..&view=ZW50aXR5 |archive-url= https://archive.today/20130121142148/http://ee.dominionpost.com/Olive/ODE/DominionPost/LandingPage/LandingPage.aspx?href=RFBvc3QvMjAxMC8wOS8xNg..&pageno=Nw..&entity=QXIwMDcwNA..&view=ZW50aXR5 |url-status= dead |archive-date= January 21, 2013 |access-date= September 16, 2010 |work= The Dominion Post |location= Morgantown, WV |page= 1B}}</ref>  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.<ref name="Less Likely">{{cite news |author= Staff |title= New Toll Roads Less Likely |date= June 13, 2011 |work= [[West Virginia MetroNews|MetroNews]] |location= Charleston, WV |access-date= June 13, 2011 |url= http://www.wvmetronews.com/news.cfm?func=displayfullstory&storyid=46032}}</ref>

==History==

===Early history===
The Mon–Fayette Expressway was originally proposed in the 1950s as a way to link the [[Coke (fuel)|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. This segment consisted of a partial cloverleaf interchange at U.S. Route 40 and a {{convert|2|mi|km|adj=on}} stretch of four-lane highway that spurred south of the new interchange toward [[Fredericktown, Pennsylvania|Fredericktown]]. Despite severe financial constraints, PennDOT built the remainder of the ramps at the U.S. 40 cloverleaf along with a separate {{convert|2|mi|km|adj=on}} stretch of highway near [[California, Pennsylvania|California]] in the early 1980s.{{Cn|date=October 2022}}

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|''Mon''ongahela 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.{{Cn|date=October 2022}}

In 1985, the Mon–Fayette Expressway project was transferred to the [[Pennsylvania Turnpike Commission]] (PTC) under Act 61 legislation. 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. Funding appropriated through the PTC allowed construction to resume in 1988, and on October 12, 1990, the entire stretch from [[U.S. Route 40 in Pennsylvania|U.S. Route 40]] to [[Interstate 70 in Pennsylvania|Interstate 70]] opened to traffic. 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 {{convert|4|mi|km|adj=on}} stretch of the expressway south of [[Uniontown, Pennsylvania|Uniontown]]. Aside from being part of a larger project, the new segment was designed to provide high speed access between the [[U.S. Route 119 in Pennsylvania|Uniontown bypass]], [[Fairchance, Pennsylvania|Fairchance]], and a new business park. This section, dubbed the Chadville Demonstration Project, opened in November 1992.{{Cn|date=October 2022}}

The section of the highway from US&nbsp;40 to I-70 was signed '''PA&nbsp;43&nbsp;Toll''' until 2000, and in 2001, it was officially named the '''James J. Manderino Expressway''' in honor of [[James J. Manderino]], a Pennsylvania State Representative who pushed for the construction of the highway.<ref name="pahighways">{{Cite web|url= http://www.pahighways.com/toll/PATurnpike43.html |title= PA Turnpike 43 |first=Jeffrey J.|last=Kitsko|website=Pennsylvania Highways}}</ref><ref name=":0">{{Cite web |title=2001 Act 17 |url=https://www.legis.state.pa.us/cfdocs/legis/LI/uconsCheck.cfm?txtType=HTM&yr=2001&sessInd=0&smthLwInd=0&act=17&chpt=0&sctn=1&subsctn=0 |access-date=2024-09-08 |website=The official website for the Pennsylvania General Assembly. |language=English}}</ref>

In the early 1990s, the Pennsylvania General Assembly dedicated a portion of state fuel excise tax revenue to the PTC. This new revenue stream initially provided the funding to complete an {{convert|8|mi|km|adj=on}} section from the southern terminus of the Chadville Demonstration Project to the West Virginia state line as well as a {{convert|17|mi|km|adj=on}} section from the Interstate 70 interchange to [[Pennsylvania Route 51]] in [[Jefferson Hills, Pennsylvania|Jefferson Hills]]. On March 1, 2000, most of the section between the Chadville Demonstration Project and the West Virginia state line opened to traffic.

===J. Barry Stout Expressway===

Officially named in 2001 for [[Barry Stout]], the Pennsylvania 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.<ref name=":0" /> The [[Joe Montana Bridge]], named after the [[Pro Football Hall of Fame]] [[Joe Montana|quarterback]] who grew up in the immediate area in nearby [[Monongahela, Pennsylvania]],<ref>{{cite journal |url= http://msc.aisc.org/globalassets/modern-steel/archives/2003/11/2003v11_mingo.pdf |title= The Mingo Creek Viaduct (Joe Montana Bridges) Washington County, PA |journal= Modern Steel Construction |date= November 2003 |location= Chicago |publisher= American Institute of Steel Construction |issn= 0026-8445 |access-date= June 25, 2015}}</ref> is located along the route.

===Uniontown-to-Brownsville===

In 2006, construction began on a {{convert|17|mi|km|adj=on}} 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 {{convert|8|mi|km|adj=on}} section of expressway running parallel to a hazardous stretch of U.S. Route 40 between [[Brownsville, Pennsylvania|Brownsville]] and Uniontown. Phase 1 opened on October 23, 2008. The second phase consisted of a {{convert|9|mi|km|adj=on}} 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 {{convert|58|mi|km|adj=on}} stretch of highway between I-68 and the current northern terminus at [[Pennsylvania Route 51]] in [[Jefferson Hills, Pennsylvania]].{{Cn|date=October 2022}}

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 {{convert|2.5|mi|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, West Virginia|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 [[American Recovery and Reinvestment Act|ARRA]] fund infusion.<ref name="Closer to Cheat">{{cite news |title= Mon–Fayette Expressway Moves Closer to Cheat |date= July 6, 2009 |work= [[The Dominion Post (Morgantown)|The Dominion Post]] |location= Morgantown, WV |page= 4A |access-date= July 6, 2009 |url= http://ee.dominionpost.com/Repository/ml.asp?Ref=RFBvc3QvMjAwOS8wNy8wNiNBcjAwNDAw&Mode=Gif&Locale=english-skin-custom}}{{dead link|date=June 2015}}</ref><ref name="Robbins">{{cite news |url= http://www.pittsburghlive.com/x/pittsburghtrib/news/fayette/s_614356.html |title= Expressway Plan Hailed for W.

Likewise, the PTC opened the southernmost {{convert|1.7|mi|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.<ref name="Shaner">{{cite news |last= Shaner |first= Cassie |title= W.Va.

==Future==
The remaining {{convert|13.7|mi|km}} of highway in Allegheny County between PA&nbsp;51 and I-376 has yet to be constructed. 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 affected by the expressway's construction.  The preferred route was identified as running parallel to PA&nbsp;837 through the communities of [[Clairton, Pennsylvania|Clairton]] and [[Duquesne, Pennsylvania|Duquesne]], crossing over the Monongahela River near [[Kennywood Park]], and then continuing along the northern side of the river through [[Braddock, Pennsylvania|Braddock]], [[Rankin, Pennsylvania|Rankin]], and [[Glen Hazel]], finally connecting to I-376 at [[Oakland (Pittsburgh)|Oakland]].  An eastern spur would be located near the crossing and continue north through [[Turtle Creek, Pennsylvania|Turtle Creek]] and [[Monroeville, Pennsylvania|Monroeville]] to I-376 in [[Wilkins Township, Pennsylvania|Wilkins]]. The addition of the spur allows for an alternative to I-376 that would bypass the often congested [[Squirrel Hill Tunnel]]. The western spur would have continued the PA&nbsp;Turnpike&nbsp;43 routing while the eastern spur would have continued the [[Pennsylvania Route 576|PA&nbsp;Turnpike&nbsp;576]] routing from the routes' planned junction approximately {{convert|1.7|mi|km}} south of Finleyville Elrama Road. Kennywood acquired nearly {{convert|50|acres}} of property for a potential expansion of the park on the condition that the leg to Monroeville is built.<ref>{{cite web |url=http://triblive.com/opinion/ericheyl/9806391-74/expressway-kennywood-park |title=Heyl: Possible Kennywood expansion selling point for pricey expressway plan &#124; TribLIVE |access-date=2016-02-04 |url-status=live |archive-url=https://web.archive.org/web/20160305131244/http://triblive.com/opinion/ericheyl/9806391-74/expressway-kennywood-park |archive-date=March 5, 2016 |df=mdy }}</ref>

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&nbsp;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,<ref name="Phase2">{{cite news |url= http://www.post-gazette.com/stories/local/neighborhoods-south/mon-fayette-expressway-connecting-uniontown-browsville-set-to-open-monday-644466/ |title= Mon–Fayette Expressway Connecting Uniontown, Brownsville Set to Open Monday |work= Pittsburgh Post-Gazette |date= July 12, 2012 |access-date= July 23, 2013}}</ref> although funding was secured for the section of [[Pennsylvania Route 576|PA&nbsp;Turnpike&nbsp;576]] in between [[Interstate 79]] and its current eastern terminus at [[U.S. Route 22 in Pennsylvania|US&nbsp;22]], bringing hope for an eventual completion of the Mon–Fayette Expressway.<ref name="Southern2">{{cite news |last= Gillooly |first= Amanda |date= December 21, 2012 |url= http://canon-mcmillan.patch.com/articles/turnpike-commission-to-proceed-with-beltway-project-lawmaker-lauds-the-move |title= Turnpike Commission to Proceed with Beltway Project, Lawmakers Laud the Move |work= Canon-McMillan, PA Patch |access-date= July 23, 2013 |url-status= dead |archive-url= https://web.archive.org/web/20121227113018/http://canon-mcmillan.patch.com/articles/turnpike-commission-to-proceed-with-beltway-project-lawmaker-lauds-the-move |archive-date= December 27, 2012 |df= mdy-all }}</ref><ref name="Phase2South">{{cite news |url= http://www.post-gazette.com/stories/news/transportation/turnpike-commission-restores-plan-for-southern-beltway-667327/ |title= Turnpike Commission Restores Plan for Southern Beltway |work= Pittsburgh Post-Gazette |date= December 21, 2012 |access-date= July 23, 2013}}</ref>{{needs update|date=February 2025}}

In July 2013, the Allegheny County portion of the expressway was again the subject 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 [[Martin Luther King Jr. East Busway|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 lane|high-occupancy vehicle]] (HOV) traffic.<ref>{{cite news |title= Leading Mon–Fayette Expressway Supporter Changes Lanes |first= Jon |last= Schmitz |url= http://www.post-gazette.com/stories/local/region/leading-mon-fayette-expressway-supporter-changes-lanes-696148/ |newspaper= Pittsburgh Post-Gazette |date= July 20, 2013 |access-date=July 25, 2013}}</ref>

In December 2014, it was reported that the Mon–Fayette Expressway and the Southern Beltway might get additional funding through [[Immigrant investor programs|foreign investors]] who obtain an [[EB-5 visa]] in exchange for investing at least $500,000 for public projects. The Pennsylvania Turnpike Commission will use EB-5 funding for the [[Pennsylvania Turnpike/Interstate 95 Interchange Project]] first before determining if it will use such funding for other projects.<ref>{{cite news |first= Bobby |last= Kerlik |url= http://triblive.com/news/allegheny/7286651-74/investors-program-china#axzz3MK1GEaTH |title= Investors Eager to Trade Cash for Green Cards in Immigration Program |work= Pittsburgh Tribune-Review |date= December 13, 2014 |access-date= December 19, 2014}}</ref>

On June 18, 2015, the PTC announced that the segment for the Mon–Fayette Expressway from Jefferson Hills to Monroeville will receive some Act&nbsp;89 funding and will return to the design phase.

In the 1990s, the Mon–Fayette Expressway project was expanded to include another highway, the [[Pennsylvania Route 576|Southern Beltway]]. The Southern Beltway is planned to be a high-speed east–west link between the Mon–Fayette Expressway, [[Interstate 79 in Pennsylvania|Interstate 79]], [[U.S. Route 22 in Pennsylvania|U.S. Route 22]], [[Interstate 376]], and [[Pittsburgh International Airport]]. A {{convert|6|mi|km|adj=on}} section of the beltway between Pittsburgh International Airport/Interstate 376 and U.S. Route 22 opened to traffic in 2006.<ref>{{cite web |author= Pennsylvania Turnpike Commission |url= https://www.patpconstruction.com/monfaysb/376.aspx |archive-url= https://web.archive.org/web/20141117163734/http://www.patpconstruction.com/monfaysb/376.aspx |url-status= usurped |archive-date= November 17, 2014 |title= Mon–Fayette Expressway & Southern Beltway Projects |publisher= Pennsylvania Turnpike Commission |date= 2014 |access-date= June 25, 2015}}</ref>  The new road has been designated as [[Pennsylvania Route 576]]. A {{convert|13|mi|km|adj=on}} section between U.S. 22 and I-79 is expected to be open by 2021, 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.<ref name="Southern2" /><ref name="Phase2South" />

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.{{Cn|date=October 2022}}
