It is indeed a very unique bridge, and I regret not hitting these things earlier. Canadian National replaced an old pin connected deck truss last year on this line. Unfortunately, as the frac sand industry continues to grow, these bridges will be replaced. Fortunately for this structure, the additional piers may have stabilized it and kept it off the replacement radar for years to come. Only time will tell.
I encourage all to alert me to coverage gaps or bridges they would like to see pictures of at the email above. I normally am on top of coverage of bridges in the region, however some slip by. Bridges in Minnesota, Wisconsin or Iowa I can typically cover in a timely manner.

It is a very pretty bridge. Thanks for the pictures John. And now I feel as though I have personally let Nathan down after all the help he's given me.

I am VERY irritated that this fascinating bridge is only now appearing with photos on Bridgehunter, since I was in this area a couple years ago and had no idea there was this EXTREMELY unusual skewed Railroad Camelback pony truss, featuring the unusual built-up beam composition that is sometimes found on railroad bridge. At least we have John taking care of these critical coverage gaps.

The CN has taken the line west or Arcadia, Wisc out of service. It is not abandoned so it could be put back into service at some point in the future, but no longer sees rail traffic nor is being maintained.
