South Platte River Bridges (also known as the Bronco Arch Bridge) were a pair of historic arch bridges that carried Denver's Valley Highway, since designated Interstate 25, over the South Platte River. Between May 2011 and August 2013, these bridges were replaced due to deterioration of the structures.[1]
