Located along Iowa Highway 140 between Moville and Kingsley, this large concrete arch bridge crosses an unnamed ditch.
Built in 1924 to replace an older trestle, the bridge consists of a single concrete arch span, using a standard design. It is unknown what contractor built this bridge, or if it was built by company forces.
Spans like this are common on American railroads due to the durability and ease of construction.
Overall, this bridge appears to be in fair to good condition, with no significant defects noted.
The author has ranked this bridge as being locally significant, due to the common design.
