The route goes east into town before turning northwest towards the Armstrong/Butler County line, passing through a few small villages along the way.

The route then winds north through several boroughs, including Karns City, Petrolia, and Bruin.

Further north on route, there is another intersection with PA 58 in Hovey Township, across the river from the borough of Foxburg.

The route has, for the most part, stayed on the same roads for its entire existence, with the exception of the southern terminus.

[2] When the Kittanning bypass was built, the terminus was moved to its current location.
