This small concrete encased I-Beam bridge crosses Fletcher Avenue (County Road N33) near Yetter.
Built in 1913, the bridge consists of a single concrete encased I-Beam span, set onto concrete substructures. A pair of concrete slab spans also approach the bridge on the east end.
The concrete encased beam span is typical of other bridges along this route. This span type allows for a much longer main span than a typical slab span.
Overall, the bridge appears to be in fair condition. Some deterioration was noted on the bridge.

The author has ranked the bridge as being locally significant, due to the common design.
