The daily Sioux City, IA, to Waterloo, IA, local blast past this old wooden bridge a few miles west of Cedar Falls. Many of the old wooden bridges along the Iowa Zone have been torn down the past few years. This bridge here at MP 288 doesn't see much traffic as it serves as a road for the farmer to get to his fields. L570 is 12 miles from Waterloo where these cars will be switched out for tonight's outbound M338.
