Located south of Plymouth near the intersection of 575th Avenue, this simple deck girder bridge crosses 719th Road.
Built in approximately 1900, 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, 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. It is unknown if Lassig or American Bridge actually built this bridge for this reason.
Several bridges in Gage County have plaques that read Lassig, although the one bridge with a plaque remaining between DeWitt and Jansen gives a 1901 date and American Bridge Company.
However, this bridge is the same size and same design than the span that does have a plaque. For this reason, the author is assuming that American Bridge Company built this span at their Lassig plant.
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 to good condition, with no serious deterioration noted. Some cracking and spalling was evident throughout the structure.

The author has ranked this bridge as being locally significant, due to the common design.
