ADDITIONAL INFO:
This bridge exhibits the more common design features of the County's stone bridges -- parapets with rounded top and horizontal curves at the portals.

This bridge shows unusual proportions compared to the many other of its type in the county. The relatively short 11-foot span is countered with tall outer walls -- approximately 30 feet from base to parapet. Typically these bridges are longer than they are tall.

The downstream wall has been rebuilt in concrete.
