 The Bunbury Street tunnel in Footscray, Victoria, on the Independent Goods Line runs under Bunbury Street (where it was constructed by cut and fill, but included a section of concrete arch and another with a concrete beam roof), passing under the Williamstown platforms of Footscray station.The line was built in 1924 to alleviate congestion caused by country goods trains on the suburban network.The Melbourne City Loop was constructed as four separate tunnels between North Melbourne and Flinders Street station, roughly following the alignment of Spring Street and Latrobe Street with underground stations at Parliament, Melbourne Central and Flagstaff.
