Sydney Metro, Australia

The expansion of local public transport around Sydney is characterized by superlatives: Sydney Metro is the largest project in the Australian public transport network, the first fully automated metro rail line in Australia and has some of the longest railway tunnels in Australia. When completed by CIMIC and its partners, the 31 station, 66-kilometer long network will connect dozens of suburbs and thousands of commuters to the Sydney central business district (CBD) faster and more comfortably every day. Spectacular: The 15.5-kilometer-long twin tunnels from Chatswood to Sydenham run deep underneath the Harbour Bridge. HOCHTIEF and CIMIC are building with a transnational team in Essen and Sydney - Stage 1 opened in 2019 and Stage 2 is opening in 2024.
