Located near Shopiere, this standard I-Beam bridge crosses County Road J.
Built in 1928 to replace a similar bridge, the bridge consists of a single I-Beam span set onto stone abutments.
These stone abutments date to 1905, when the previous bridge was constructed. Overall, the bridge appears to remain in good to fair condition.
The author has ranked the bridge as being locally significant, due to the common design.
The photo above is an overview. The bridge can be accessed from the road it crosses.
