Pennsylvania Route 150

Pennsylvania Route 150 (PA 150) is a 41.1 mi highway in Central Pennsylvania. Its southern terminus is at PA 26 in Dale Summit, Pennsylvania near State College, at the location of the Nittany Mall. Its northern terminus is at U.S. Route 220 (US 220) in Avis.

Since the construction of Interstate 99 (I-99) in the area north of State College, the major use of the southernmost portion of PA 150 is to connect traffic from the expressway to downtown State College and Pennsylvania State University (via a section of PA 26).

The names of this road include Benner Pike, Main Street, Willowbank Street, Water Street, Bald Eagle Valley Road, High Street, Bellefonte Avenue, Church Street, and Woodward Avenue. The route is also concurrent with PA 144 between Bellefonte and Milesburg, in addition to PA 550 briefly in Bellefonte.

The route was signed in 1928 and in 1930, the route was paved from Hublersburg to Howard.
