180th Street Bridge
Posted August 22, 2012, by Don Morrison

Q. What if they put a 75 foot high dam in the area of Peterson Pits, holding back 94,000 acre-feet of water?

A.They almost did, planned to be complete in 1976. The Skunk River bridges from Ames to Story City would have been inundated under the surface of Ames Lake.

"Bridges and causeways are planned at Soper's Mill and at the site of another present bridge two miles upstream. The bridge a mile below Soper's Mill would be abandoned."

At least this old bridge got to serve it's purpose until 2011.

This bridge is in the process of being removed and replaced. Tis a shame to see it go. http://www.storycounty.com/index.aspx?DN=7560,18,6,1,Documen...
