Located between Altoona and Pleasant Hill, this unique concrete arch bridge is a remain of the line towards Pella.
Built in 1896, the bridge features a small concrete arch span, crossing an unnamed tributary of Little Fourmile Creek.
Typically, railroads did not begin building concrete arches until after 1900. This appears to be an early version of a concrete arch.
Unfortunately, the arch has significant structural issues. The main arch line has entirely failed, putting a massive hole in the west wall. In addition, severe scouring will eventually cause the east wall to fail as well.
It is unknown who currently owns the bridge, but it is easily accessed from the Gay Lea Wilson Trail.
The author has ranked this bridge as being locally significant, due to the common design.
