Township in Fayette County, passing through forested areas with some fields. The first interchange in the state is at Gans Road, which provides access to US 119 to the west and PA 857 to the east. Here, PA Turnpike 43 becomes a toll road and continues northeast through more rural areas, where it crosses into Georges Township and comes to a diamond interchange with Rubles Mill Road that accesses PA 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 119 and PA 857. 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 the road becomes US 119. PA 43 continues as an unsigned concurrency with US 119 for around Uniontown, with a sign saying that PA 43 traffic should follow signs for US 119 through Uniontown. A short distance later, US 119 and the unsigned PA 43 cross together into South Union Township and reach an interchange with the US 40 freeway, at which point US 40 merges with US 119 and the unsigned PA 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 40/US 119/unsigned 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 Business, at which point US 40 splits to the northwest. US 119 and the unsigned PA 43 continue northeast on the freeway into North Union Township, where they run between rural areas to the northwest and residential areas to the southeast. The unsigned concurrency ends as PA Turnpike 43, again a toll road maintained by the PTC, splits from US 119
