Located south of Neola, this large pony truss is the 7th crossing of Mosquito Creek.
Built in 1932, this bridge replaced an older pony truss bridge, which was reused across the Big Sioux River. Currently, the bridge consists of a single 8-panel riveted Warren Pony Truss. This span is approached by a pair of through girders on the west end, which date to 1911. The bridge rests on concrete substructures.
It appears that the early 1930s were a time of rebuilding along this route, and many bridges were replaced. This truss was a common design to replace smaller through trusses between 1927 and 1931.
Overall, the bridge appears to be in good condition, with little noted deterioration.
The author has ranked this bridge as being moderately significant, due to the truss design.
