Is that in Milbank? I looked around the vicinity and on Google and couldn't find a Thresher Bee Park in that area. I updated the status but wanted to mark the proper location. Thanks!

This bridge is not lost but was relocated to the threshing bee park grounds and was reset to cover a small ravine on the grounds. I live right next to where the bridge was located.
