Project Benefits


The CWB Project can bring the following benefits to the public:

  1. Enchance Transport Network
    Upon commissioning, CWB reduces the traffic time between Central and IEC to 5 minutes, making the linkage between the east of Hong Kong Island and other districts in the western side of the territory more smooth and direct.
  2. Protect the Environment
    Mitigate traffic noise nuisance: Noise barriers and noise semi-enclosures will be erected at North Point section of IEC. Traffic noise at the nearby households could be effectively reduced by around 16dB in average and 25.6 dB at maximum.

    Improve air quality: Diverts existing at-grade traffic to underground to improve the air quality of surrounding areas. In addition, by shortening the travelling time, the annual emission of CO2 could be reduced by around 11 000 tonnes, equivalent to that absorbed by 480 000 new trees per year (covering an area of over 67 numbers of Victoria Park). Together with the first Air Purification System adopted in Hong Kong road tunnels which could effectively remove 80% of respirable suspended particulates (RSP) and nitrogen dioxide (NO2), the air quality would be improved.

    Beautify urban environment with greening elements: Tunnel buildings with greening elements will be erected. The roof of the East Tunnel Portal will be developed into a landscaped deck. Large number of vegetation will be planted along CWB providing a total of 4.5 hectares greening area to beautify the urban environment.
  3. Facilitate Urban Development
    Reserve at grade open space and develop a new waterfront promenade: 80% of the CWB is constructed in the tunnel form, thereby reserving the at grade open space for other form of development. Additional land was also formed which allowed the future development of a waterfront promenade.
