Cross Harbour Tunnel
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 in 1972.
The Cross-HarbourTunnel is an underground (underwater) tunnel built in the early 1970s to link the Kowloon peninsula with Hong Kong Island. It was the first of our three vehicular crossings and is now one of the most congested passageways in the world with a silly number of vehicles making the crossing back and forth each day. Length 1.86 kilometres.
