The Ten Mile Creek Bridge, now located on the Trout Run Trail, originally spanned Ten Mile Creek about five miles northwest of Decorah. It was dismantled and relocated to Trout Run Trail in the spring of 2011.
The R.D. Wheaton Bridge Company of Chicago built the bridge around 1895. It features a kingpost pony truss design, one of the simplest types of trusses, dating back to the Middle Ages.
Many kingpost bridges were constructed on Iowa’s early roads in the late 19th and early 20th centuries, initially using a combination of timber and iron and later in all-metal configurations. The kingpost design is generally limited to relatively short spans.
On a personal note, I have hiked and fly-fished at the original site of the Ten Mile Creek bridge. All that remains now are the concrete abutments of the bridge, and Happy Hollow Road (yes, that's really its name) now dead-ends on both sides of the creek.
