Four historic bridges on the Big Thompson River in Larimer County, Colorado survived its flood of 1976, but since have lost most of their historic integrity. They were built in 1933 and 1937. All four were listed on the National Register of Historic Places in 2002, and two were delisted in 2010. Read more on Wikipedia
