The St. Louis Freight Tunnel is a historic railroad tunnel beneath Washington Avenue and Eighth Street in downtown St. Louis. Completed in 1874, it carried freight and passenger trains between the Eads Bridge and the rail yards in the Mill Creek Valley, bypassing busy downtown streets. It fell into disuse after 1974 and sat dormant for nearly two decades before being refurbished by 1993 for use by MetroLink, the light rail system in Greater St. Louis.
