Description 

From Historic Bridge Inventory:

The bridge carries a 2 lane road over a stream in a forested setting with scattered late-20th century residences. The setting does not have historic district potential.

The skewed, one-span, 36'-long, reinforced concrete rigid frame bridge built in 1927 is finished with concrete balustrades. Plain concrete parapets continue over the U-shaped wingwalls. Although modest in length and decorative detail, the bridge is the oldest example of the rigid frame bridge type in the state survey. As such, it documents an early application of a historically important bridge technology in the state context. The rigid frame bridge type was introduced to this country in the early 1920s when it was used on the Westchester County (NY) parkways. It first appeared in Pennsylvania during the late 1920s with designs prepared by county and municipal engineers, such as Delaware County Engineer George Wright, who designed this example. The technology, which results in well proportioned spans with clean lines, is still used today.
