Located east of Lamberton, this small girder bridge crosses a field access road.
Built in 1916, the bridge features a small deck girder span set onto concrete abutments. This girder is not as built up as larger deck girders, and uses a four beam arrangement.
Overall, the bridge appears to be in good condition. Chicago Bridge & Iron Works did a lot of work throughout this area between 1916 and 1918.
The author has ranked this bridge as being locally significant, due to the common design.
