One of several such arches in the area, this small stone arch crosses a local pedestrian path.
Built in 1902, this is one of several similar arches along this line that were constructed at the same time. The bridge consists of a single stone arch span, constructed of Ablemans Sandstone.
The bridge originally crossed a small ravine. Since then, it has been reused and made accessible as a trail.
Overall, the bridge appears to be in good condition. Like most stone arches, this structure has little sign of deterioration.
The author has ranked this bridge as locally significant, due to the number of similar arches in the area.
The photo above is an overview. The bridge can be accessed from the trail it crosses.
