Located north of Jansen near the intersection of 575th Avenue, this simple deck girder bridge crosses 717th Road.
Built in 1901, the bridge is like many others between Lincoln and Jansen. All of these spans have plaques indicating Lassig Bridge & Iron Works of Chicago fabricated the spans. However, this bridge is the only one with a plaque which indicates it was built by the American Bridge Company Lassig Branch in Chicago.
When Lassig was purchased by American Bridge Company in 1900, American Bridge kept the Chicago factory open and continued using the same design of plaques through 1902.
The bridge itself is a single span deck plate girder, set onto large concrete abutments. In addition, a small 4'x4' box culvert runs under the west abutment.
Overall, the bridge appears to be in fair condition, with some serious deterioration noted. The worst deterioration includes the massive cracks beginning to form in the abutments.

The author has ranked this bridge as being locally significant, due to the common design.
The photo above is an overview. Unfortunately, the angle of this bridge and the solid walkway made getting good photos of it impossible.
