Grant Wasden had a question about Grandpa Wasden being involved in the construction of the corkscrew bridge in Yellowstone. I'm not sure I have the name of the bridge right, but it is the circular bridge. Unfortunately I can't find the Facebook post with the picture on it. However, if any one has any information from memory or from records about this bridge, please let us know. I do remember something about Grandpa's involvement with this bridge but that's as far as my memory goes.
