Pennsylvania Route 158 (PA 158) is an 11.9-mile-long (19.2 km) state highway located in western Pennsylvania, running from PA 18 south of New Wilmington in Lawrence County, to US 62 and PA 258 in Mercer in Mercer County.

Route description

Traveling north from PA Route 18, PA 158 heads into the borough of New Wilmington, where it passes Westminster College and intersects with PA Route 208. The two routes briefly overlap eastbound; at the intersection with PA 956, the concurrency ends, and PA 158 continues northward. As it leaves the borough, it enters Mercer County and winds northeasterly through rural countryside nearly 6 miles (9.7 km) before it passes over I-80. Approximately 3 miles (4.8 km) later, the route enters the borough of Mercer, where it meets the eastern terminus of PA Route 318 just one block before its own northern terminus at the US 62/PA Route 258 concurrency.

History

In 1927, what is now PA 158 was originally designated part of PA 18.^[2] A year later, the road was signed as PA 158^[3] when PA 18 was moved to its current alignment between PA 158 and Greenville.^[2]
