Located south of Carlisle, this large deck girder bridge crosses the Middle River.
Built in 1912, the bridge consists of four standard deck girder spans, set onto concrete substructures. It is unknown if these spans were originally built here, or if they were moved from elsewhere, as some other bridges on this line were.
Girder bridges like these are common in multiple span structures to cross larger rivers and streams.
Overall, the bridge appears to be in good condition.

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