One of the weirder bridges in Iowa City is this massive two span concrete crosses Ralston Creek.
Built in 1901, the arch has a weird appearance. The massive center pier provides a unique appearance to this bridge.
Otherwise, the bridge has little notable differences from other arches. The build date of 1901 is assumed, from when the Rock Island double tracked this line. It also may be possible this is an encased stone arch bridge.
Overall, this bridge remains in good condition.
The author has ranked this bridge as being moderately significant, due to the unique design and older age.
