The highway stays parallel until US 20 makes a sharp left turn and intersects with PA 955.

The route was first signed in 1928 and widened from PA 5 to an intersection with Nagle Road with a grassy median between 1950 and 1958.

The highway progresses eastward along Iroquois Avenue, crossing through a local residential complex as a two-lane roadway.

Separated by a grassy median, PA 955 heads eastward into a commercial district for Lawrence Park Township near the intersection with Smithson Avenue.

[2] Prior to 1928, the state ran PA 955 as the Iroquois Avenue Extension, using its entire alignment as a non-state highway from Lawrence Park to an intersection with then Legislative Route 87 in the community of Harborcreek.
