Description 

This short-span crossing of Ten Mile Creek is located some five miles northwest of Decorah in central Winneshiek County. County records do not refer specifically to this kingpost pony truss, but it appears to have been built circa 1895, probably by the R.D. Wheaton Bridge Company of Chicago, which supplied several kingpost trusses to the county at that time. Consisting of a kingpost pony truss with rigid-connected upper chords and pinned lowers, the structure is supported by stone abutments. Since its completion, the Ten Mile Creek Bridge has continued to carry intermittent traffic in its picturesque setting, while retaining an exceptional degree of structural integrity. With its roots extending to the Middle Ages, the kingpost pony truss was the most rudimentary truss type. Numerous kingposts were built on Iowa's early roads in the late 19th and early 20th centuries, executed first as timber/iron combination structures and later in all-metal configurations. The Kingpost as a structural type was generally limited to relatively short-span applications, however, and as steel beam bridges received widespread acceptance after the turn of the century, erection of kingpost trusses declined rapidly. This bridge in Winneshiek County is a well-preserved example of this mainstay structural type [adapted from Crow-Dolby and Fraser 1992].

King post is possibly at 43.274223, -91.793415.

It's too small to cross Trout Run. (I think)

Looking at the location of the bridge on the map, it appears that it is a MOB. I'm also concerned because of the removal from the NRHP. Does anyone have any insight into this?

This bridge has been moved to the City of Decorah and looks great on the new bike trail.

That is excellent news. It sounds like the Decorah Bike Trail is going to have quite the collection of historic bridges.

This bridge will be moved to the bike trail for the City of Decorah in the Summer of 2010.
