This standard concrete slab bridge crosses Jade Avenue east of Templeton.
Built in 1913, the bridge features a standard design. This standard design is considered to be a concrete slab, although it is commonly considered a box culvert. The bridge rests on concrete substructures.
Single span slab/culvert structures were built at many road crossings during the relocation and reconstruction of this route. The design is extremely common, and is well suited for small spans.
Overall, the bridge appears to be in good condition. Some spalling and cracking has occurred on the entire structure, and one large crack inside the structure appears to have formed a hole in the wall.

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