This unique overpass crosses over the former Milwaukee Road mainline in an area of Chaska known as Jonathan.
Originally built as a wagon bridge in 1913, the structure reused a girder span from a bridge over the Des Moines River at Madrid, Iowa.
It is unknown when that bridge was built, but past truss bridges were built in 1888 prior to being replaced in 1911 and 1912.
When the bridge was reused, the main girder span was dissembled. Likely originally a deck girder, the bridge received a new floor and functions as a through girder currently.
In addition to this unique main span, the bridge is approached by trestle spans. It sits on wooden and concrete substructures.
However, the bridge was closed in 2008. With Chaska growing little north of the bridge, it is a low priority for the county to replace. It currently is in a closed status.
The technique of reusing railroad spans for road use isn't new, although this is one of the only known examples of a structure like this along Milwaukee Road.
Overall, the bridge is in poor condition. Unfortunately, the bridge is in a severely deteriorated condition and will be demolished in the future.
In 2020, the TC&W built a second track (siding) underneath the bridge for car storage and parking, as a result of the Southwest Light Rail project.
The author has ranked this bridge as being regionally significant, due to the unique design.
