Pennsylvania Route 551 (PA 551) is a 34-mile-long (55 km) state highway located in Beaver, Lawrence, and Mercer Counties in Pennsylvania. The southern terminus is at PA 18 in Beaver Falls. The northern terminus is at PA 18 near West Middlesex.

Though officially a spur route of Pennsylvania Route 51, PA 551 is more suited as a spur route of PA 18, due to PA 551 ending at PA 18 at both ends without intersecting with PA 51 at all. (PA 51 and PA 551 come within a mile of each other near Darlington, Pennsylvania at their closest point.) While PA 18 passes through larger cities, PA 551 goes through more rural areas.

Route description[edit]

Beaver County[edit]

PA 551 begins at an intersection with PA 18 in Beaver Falls, Beaver County, heading west on two-lane undivided 49th Street Extended. The road passes between commercial areas to the north and homes to the south, crossing under Norfolk Southern's Fort Wayne Line and heading into West Mayfield, becoming Wallace Run Road. The route heads into wooded areas with some homes, crossing Wallace Run into Big Beaver. PA 551 continues northwest along the northern bank of Wallace Run, coming to an interchange with I-376 that has a toll plaza on the ramps to and from the northbound direction of I-376. The road heads into a mix of farmland and woodland with some residences, curving more to the west. The route heads southwest and crosses into Chippewa Township, turning northwest and briefly passing through Big Beaver again prior to entering Darlington Township. PA 551 curves west and heads into South Beaver Township, where it turns north onto Old Darlington Road and comes to an intersection with PA 168. Here, PA 168 turns north to form a concurrency with the route, crossing the North Fork Little Beaver Creek into Darlington Township. The road heads into Darlington and becomes Market Street as it heads through residential areas, with PA 168 splitting to the east in a commercial area. PA 551 continues north past more homes, turning east onto 5th Street as it forms the border between Darlington to the south and Darlington Township to the north. The route turns north onto Hollow Road and fully enters Darlington Township, heading into a mix of farms and woods with some residences. The road curves to the northwest as it heads through more rural areas.[1][2]

Lawrence County[edit]

PA 551 enters Enon Valley in Lawrence County and becomes Main Street, heading into residential areas and crossing Norfolk Southern's Fort Wayne Line. The route intersects PA 351 and becomes concurrent with that route, soon heading north onto State Street as it passes more homes. The road heads into Little Beaver Township and becomes unnamed, heading through more areas of farms, woods, and residences as it passes through Old Enon. PA 351 splits to the northwest and PA 551 continues north on Enon Road, crossing the North Fork Little Beaver Creek again and continuing through more farmland and woodland with a few homes. The road heads into open agricultural areas with occasional residences, passing over I-76 (Pennsylvania Turnpike). The route crosses into North Beaver Township and runs through Newburg, continuing through more rural areas. PA 551 heads through more farmland with some woods and homes as it comes to a junction with PA 108. At this point, PA 108 turns north to form a concurrency with PA 551, with the name changing to Mt. Jackson Road. The road curves northeast through more agricultural areas with some woodland and residences, turning more to the east into wooded areas with some homes. In the community of Mount Jackson, PA 551 splits from PA 108 by heading north along with PA 317 on Mohawk School Road. The road passes farms and homes before PA 551 splits from PA 317 by heading north on Edinburg Road.[1][3]

Entering Edinburg from the west

The route runs through farmland and woodland with some residences, crossing into Mahoning Township. PA 551 crosses a Norfolk Southern railroad line and becomes Erie Street, heading into the residential community of Edinburg. Here, the route turns west onto Jackson Street and passes more homes before heading through farm fields and curving northwest. PA 551 comes to an intersection with US 224 and turns northeast to join that route on West State Street. The road heads through wooded areas and crosses the Mahoning River and two CSX railroad lines. PA 551 splits from US 224 by heading north on North Edinburg Road, continuing through wooded areas with some farmland and homes. The road crosses US 422 and continues through more rural areas, heading north-northeast and entering Pulaski Township. The route becomes an unnamed road and runs north through more farmland and woodland with some residences, curving northwest and north again. PA 551 comes to an intersection with PA 208 and turns northeast to join that route, heading through woodland to the west of the Shenango River. The two routes turn east to cross the river and head into the residential community of Pulaski. Here, PA 551 splits from PA 208 by turning northeast onto Mercer Street, curving north as it passes between industrial areas to the west and I-376 to the east.[1][3]

Mercer County[edit]

PA 551 heads into Shenango Township in Mercer County and becomes Pulaski Road, heading north-northwest through wooded areas with some industrial buildings, homes, and fields. The route continues through a mix of agricultural areas and woodland, curving north as it comes to its northern terminus at another intersection with PA 18.[1][4]
