  Shatin to Central Link Cross-Harbour Railway Immersed Tunnel

  The Shatin to Central Link is a new 17km long railway that will connect the three existing railway lines in Hong Kong to enhance connectivity of the railway network. The project includes 12 major civil construction contracts, and construction commenced in 2012. Contract 1121 involves construction of a new Immersed Tube Tunnel, and this 1.7-km long immersed tube tunnel section is the fourth cross harbour railway link crossing the harbour. When completed, the new tunnel section will extend the East Rail Line across the harbour to a new station in Wan Chai North and terminating at the existing Admiralty station. The towing out and immersion operations for this new tunnel were successfully completed in April 2018. A total of 11 immersed tube tunnel elements were cast at Shek O casting basin located in the southern part of Hong Kong Island. This cross-harbour tunnel section was procured through design-and-build contract arrangement with early contractor involvement. Upon successful completion of immersion and connection of the immersed tube tunnel elements, rail track installation and electrical and mechanical works inside the tunnel are now underway. This paper discusses the planning and construction of this latest immersed tube tunnel in Hong Kong SAR from reference design stage to successful completion of the construction.
