Keith Valley Road
Keith Valley Road, which currently extends north from Horsham Road to County Line Road, was originally a path connecting Sir William Keith's Fountain Low (Graeme Park) to the Kenderdine Mill.( 48)The current road crosses over where the millrace had been so it is likely that the road did not go past the mill until the mill stopped operating, which we believe to be in the early 1900s.
The path probably followed the current road to where it intersects with Governor Road. Governor Road was one of the earliest roads in Horsam and exists today only as a dirt road.
The bridge over Park Creek just next to the intersection with Governor Road, was built in 1907 so that its probably when the path was transformed into a road.
FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
The 2-span, 78'-long, 28'-wide stone arch bridge is laid up in random coursed ashlar. It has matched ring stones. The parapets finished with stones set in a crenellated pattern date from 1941 when the bridge was widened with a reinforced concrete arch extension to the downstream side. The stone arch intrados has been shotcreted. The bridge is an altered example of a type and design that is common in the county, and it is not historically or technologically significant. (49
