The road heads through wooded areas with agriculture, running to the north of the Enlow Fork of the Wheeling Creek.

PA 231 winds north through more areas of woods and farms with occasional homes, passing through the community of East Finley.

After passing under I-70, PA 231 becomes Bell Avenue and forms the border between Donegal Township to the west and the borough of Claysville to the east, reaching an intersection with US 40.

At this point, the route turns east to form a concurrency with US 40 on Main Street, fully entering Claysville and running past homes.

[1][2] The route crosses back into Donegal Township and heads northwest through woodland with some farms and residences as an unnamed road.
