[2] The entire route of the highway is located within Lane County.

As it emerges from the mountains, it passes through the Alderwood State Wayside, and descends into the Willamette Valley.

It then passes through the communities of Goldson and Cheshire before ending just south of Junction City at an intersection with Oregon Route 99.

The highway was originally part of U.S. Route 28 and was the primary route between the Oregon Coast and the Eugene area; however, because of its winding nature, it was not suitable for high volumes of traffic.
