Pennsylvania Route 51 (PA 51) is a major state highway that is located in Western Pennsylvania in the United States. It runs for 89 miles (143 km) from Uniontown to the Ohio state line near Darlington, where it connects with Ohio State Route 14.
PA 51 is the termination point for Pennsylvania Route 43, Pennsylvania Route 48 and Pennsylvania Route 88. The route is a major connection from Uniontown and the rest of Fayette County to Pittsburgh.
The highway is four-lane highway that is located south of Pittsburgh; it passes through Pittsburgh's South Hills before narrowing to a two-lane road through several boroughs along the Ohio River. It then becomes four lanes again after passing Chippewa Township in Beaver County and continues to the Ohio border.
In the South Hills, PA 51 (Saw Mill Run Boulevard), along with US 19, is one of the major routes in and out of Pittsburgh, as it provides access to several bridges and tunnels. PA 51 is one of the highways that enters the West End Circle, an intersection in the West End.
