TUNNELS IN VICTORIA HARBOUR

The SCL tunnel section in Victoria Harbour stretches from the southern boundary of the Hung Hom Landfall to approximately 70m north of the Causeway Bay Typhoon Shelter (CBTS), which mainly consists of the following works:

  • Construction of the tunnel section by Immersed Tube Tunnel (IMT) method, which involves dredging, trimming, laying of tunnel tubes and filling to be conducted in sequence;
  • Demolition and reprovisioning of part of Hung Hom Freight Pier; and
  • Provisional underwater blasting in case bedrock or large boulders that cannot be removed by grab are encountered.
