The O Street Viaduct was located in the South Omaha, Nebraska. Built to accommodate O Street traversing over the Union Pacific tracks, the overpass was constructed in 1885 by interests associated with the Omaha Stockyards. It was included on the Bridges in Nebraska Multiple Property Submission on June 29, 1992. The bridge was demolished in 2001 as part of the redevelopment of the stockyards.[1] [2]
