WSP to Facelift Hong Kong's Western Harbour Crossing Kowloon Portal

WSP has been appointed by Hong Kong’s Civil Engineering and Development Department (CEDD) to undertake the consultancy agreement for the investigation, design and construction for the relocation of Western Harbour Crossing administration building at the tunnel’s Kowloon portal.

Hong Kong Government has taken over the Western Harbour Crossing upon its franchise expiry and implemented the Free-Flow Tolling System, which is also designed and developed by WSP, in August 2023. As the original toll plaza geographically abuts the West Kowloon Cultural District, the relocation of the administration building will enable the district’s public infrastructure works to improve traffic connections and drive its long-term growth.

As one of the three road tunnels to cross Victoria Harbour, the relocation requires very sophisticated migration design to ensure no interruption to the Western Harbour Crossing’s safety-critical operations. WSP will hence provide leading-edge multidisciplinary services on civil, traffic, geotechnical, electrical and mechanical engineering as well as environmental, survey, architectural, and tunnel systemwide provisions consultancy that cover over 20 traffic and plant controls, telecom and radio systems as well as the integrated main control centre. Our design will enable seamless transition of the building’s existing function to the new building with minimal impact to the tunnel’s daily traffic. 

Apart from construction of a new administration building, our professional consultancy services cover its associated facilities such as carparks and access loop road. We will also be responsible of the reprovisioning of the traffic control and surveillance system at the new administration building, demolition of the existing administration building and provisioning of associated works including drainage, sewerage, traffic aids and other related engineering and ancillary works. WSP will ensure the successful delivery of this project.

Western Harbour Crossing was opened in 1997 as part of the Airport Core Programme. As the joint venture tunnel design consultant back then, WSP provided expertise on the electrical and mechanical systems, including the central monitoring and control system and the co-ordination of traffic control and surveillance system.
