This standard stone arch bridge crosses Little Fourmile Creek in Altoona.
Built in approximately 1880, this bridge features a single stone arch span with stepped and angled wing walls.
One of the worst train wrecks in Iowa history happened nearby in August 1877 during a flood, and many other bridges were destroyed. During the accident, a stone arch completely washed out. This indicates that this bridge was likely built either before 1877, or immediately after.
Unfortunately, any records able to confirm the build date for this arch are likely destroyed. The Rock Island was particularly notorious for bad record keeping.
The author has ranked this bridge as being locally significant, due to the common design of the bridge.
