This standard deck girder bridge crosses Fourmile Creek in Pleasant Hill.
Built in 1902 and 1912, the bridge features five deck girder spans, with stone and concrete substructures. Four of the girders date to 1912, while one girder dates to 1902. It is unknown what type of bridge this replaced, and if the 1902 span was moved here.
Since being acquired by IAIS, the bridge has also seen some upgrades. Heavy maintenance insures the bridge is here to stay.

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