The Cross-Harbour Tunnel is the first tunnel in Hong Kong
built underwater. It consists of two steel road tunnels each with two lanes constructed using the single shell immersed tube method.
It is the earliest of three vehicular harbour crossings in Hong Kong, opened for traffic on 2 August 1972. It was constructed under 30-year private-sector franchise based on a build–operate–transfer model, and title passed to the Hong Kong government in August 1999 upon termination of the franchise. It has become one of the most congested roads (mainly towards the Hong Kong Island direction) in Hong Kong and the World
Constructed by a private company and operated under a 30-year franchise, the 1.8 km (1.1 mi)-long tunnel crossing opened in 1972, providing the first road link between Kowloon
and Hong Kong Island. Prior to the opening of the tunnel, cross-harbour vehicular traffic depended on ferries and for passengers, the Star Ferry
The tunnel links the main financial and commercial districts on both sides of Victoria Harbour
, connecting Kellett Island (a former island now connected to Hong Kong Island by reclamation), with a reclaimed site at Hung Hom
Bay, Kowloon. The toll plaza is located at the Hung Hom end of the tunnel, and has 14 toll booths.
It was administered by The Cross-Harbour Tunnel Company Ltd until August 1999, when the operation franchise agreement expired and the government assumed control. Since 1 November 2010, the tunnel is managed, operated and maintained by Serco Group on contract basis.
