Located west of Portland near Spruce Avenue, this small through girder bridge crosses Mason Creek.
Built in 1907 using a secondhand span, this structure features a single through plate girder span, set onto concrete substructures.
This span was originally built in 1897 at Bridge #Z-994; Ferguson, Iowa. In 1906, that bridge was replaced by a new deck girder span, and the girder was reused here.
This type of span was commonly used to cross small creeks, because of the ease of installation, cheap cost and little maintenance required.
Overall, the bridge appears to be in good condition, with little deterioration. It appears some rivets have been replaced with bolts since the original construction.
The author has ranked this bridge as being locally significant, due to the common design.
