Central – Wan Chai Bypass and Island Eastern Corridor Link

Central – Wan Chai Bypass and Island Eastern Corridor Link

The Central – Wan Chai Bypass and Island Eastern Corridor Link (CWB) is a strategic trunk road running along the north shore of Hong Kong Island. It is an expressway for west-east traffic between Central and North Point, alleviating the congestion along Connaught Road Central, Harcourt Road and Gloucester Road and coping with the predicted traffic flow in the area.

The 4.5km dual three-lane trunk road consists of 3.7km long tunnel underneath the densely built-up areas and sea-bed as well as 0.8km long at-grade/elevated roads. The CWB modified the Rumsey Street Flyover, which runs to the ground, then goes underground near International Finance Centre in the form of tunnel, passing underneath Central reclamation area, the Hong Kong Convention and Exhibition Centre, the ex-Wan Chai Public Cargo Working Area and the portal of Cross Harbour Tunnel, emerges near the Causeway Bay Typhoon Shelter and finally connects to Island Eastern Corridor at North Point by a viaduct.

The CWB is equipped with the first Air Purification System in Hong Kong road tunnel, which purifies the tunnel exhaust prior to discharging it through the ventilation shafts into the atmosphere.

The CWB construction commenced in December 2009 and was commissioned in February 2019.

Harbour Area Treatment Scheme

Harbour Area Treatment Scheme

The Harbour Area Treatment Scheme (HATS) was a major Government initiative to improve the water quality in Victoria Harbour and provide a safe and healthy environment for the people of Hong Kong. It provides for the proper collection, treatment and disposal of all sewage that discharges into the Harbour from the urban areas of Hong Kong.

The HATS was implemented in 2 stages. Stage 1 and Stage 2A of the scheme came into operation in 2001 and 2015 respectively.

The HATS comprises three major components, including 1) a 44km network of deep underground sewage tunnels at over 100m average depth (168m at the deepest), 2) upgrading of 16 preliminary sewage treatment works around the Harbour and 3) The Stonecutters Island Sewage Treatment Works with a designed flow capacity of 2.45 million m3/day providing chemically-enhanced primary treatment and disinfection.

With the planning of project launched in late 1980s, the construction work of HATS spanned two decades at a total cost of HK$25.8 billion, for full commissioning of Stage 2A at the end of 2015. The system can serve up to 5.7 millions of people at both sides of the Harbour.

The HATS is a uniquely intricate and efficient system delivered through visionary planning, innovations and advanced technology. The HATS has inspired the DSD in providing cost-effective and sustainable sewerage infrastructural services to safeguard the community.
