Kudos to my wife Monica for alerting me to this bridge! She noticed it while driving by one day. This bridge is located in a private field, which is mostly maintained by the landowner adjacent to and immediately south of it, and is readily noticeable from the road. Many thanks to Doug (the adjacent landowner) for allowing me to visit this structure and take pictures! Even though the Coney River lies about 500' west of this bridge, the bridge itself doesn't cross anything. This is a mostly riveted Warren pony truss bridge, but some of the lower chord connections are bolted with square bolts which appear to be original. The bridge has no deck, and the stringers are lying on the ground in a stack next to the bridge. The end bearings have also been removed, and there are no builder plaques on it. The build date is an educated guess based on the design and construction of it. The bridge's diagonal members are back-to-back angles connected by battens, and there are also battens under the upper chord and on the lower chord. No V-lacing is present on this bridge. All of the upper connections are riveted, and the original angle railings are present (but are in pretty sad shape). Considering that it has been sitting directly on the ground, the bridge itself appears to be in very good condition and would be an ideal candidate for restoration and reuse as a pedestrian bridge , as was planned.

This bridge's history is unclear, but according to the adjacent landowner, this bridge was originally located somewhere in northern Wisconsin and was relocated here with the intention of refurbishing it and using it as a pedestrian crossing at a nearby "historical society" building, but ultimately, it ended up on this property and was never put to use. Apparently, it has been at this location for approximately 15 years. The bridge' s name is taken from the last names of two previous long-time owners of the adjacent property next to the bridge.

Thanks, Tony. I remember years ago when the Mississippi River Bridge in Jacobson, MN was removed, the news article stated that it weighed 175 tons, which I thought seemed really heavy...so I figured around 10-20 tons seemed about right for this one.

I really don't know on a pony truss Matt but I would think 10 to 15 tops. I watched a 185ft long Camelback lifted and moved into place last year and when I enquired with the foreman he told me it was about 75 tons.

Hey, could any of you experts out there give me a good approximation for the weight of this bridge? The landowner, who now owns the land and the bridge, is moving it to a spot a few hundred feet away to span a small swale and he wants to know what weight the abutments should be designed for. My guess would be 10-20 tons, but further input would be appreciated. I'm happy to see that he is going to give this bridge the future it deserves! Thanks in advance!
