Bridge Documentation

This bridge no longer exists!

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This is a steel stringer that is noted for retaining its original concrete railings. It sits on stone abutments and pier, something that would normally be unusual except that a substantial number of 20th Century bridges in Chester County do rest on stone substructures.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The 2-span, 86'-long steel stringer bridge built in 1931 is supported on stone abutments and cutwater pier. The bridge has a concrete deck and paneled concrete parapets. It has no innovative or distinguishing details and is an example of the most common, 20th-century bridge type in the state. It is one of over 4300.

Discussion of Surrounding Area

The bridge carries a 2 lane road over a stream at Dorlans Mill. The Shryrock Bros. paper mill complex with an altered 19th-century core and large mid-20th-century cinderblock additions is at the bridge's northeast quadrant. A vernacular early 19th-century stone residence is located approximately 200' northeast of the bridge. No other residences or buildings associated with the mill village's pre-1940 development have survived. According to the mill manager, the mill site goes back in use about 300 years, but only some portions of the earlier mill stone walls remain incorporated with the existing mill complex. The mill was modernized about 40 years ago with the cinderblock additions added for new machinery and storage. The setting does not retain the integrity or cohesiveness of resources for a potential historic district.
