香港機場核心計劃
Western Harbour Crossing (WHC) is the first three-lane road tunnel in Asia to be constructed using submerged pipe, and is the newest of the three Victoria Harbour road tunnels. It is part of the Airport Core Programme which was a comprehensive set of infrastructure projects associated with the airport at Chek Lap Kok. The tunnel carries on the Route 3 designation from the West Kowloon Highway, and connects to Route 4 on Hong Kong Island.
