The tracks between DeWitt and Eldridge Junction were abandoned in 1931. The Milwaukee Road rail between Maquoketa and DeWitt was abandoned by 1970. Several buildings along 7th Avenue still show signs of former rail loading and unloading uses. These include a former paper box factory (now apartments) at the northwest corner of 7th Avenue and 7th Street as well as various sheds and elevator buildings between 5th and 7th Streets. What had served as the Chicago & Northwestern's Depot was destroyed by fire circa 1969 and never rebuilt. The depot for the Milwaukee Road's Depot was at the northeast corner of 7th Avenue and 7th Street. It was converted into commercial use, but has since been demolished.
