Western Harbour Crossing

The Western Harbour Crossing (WHC) is a dual three-lane immersed tube tunnel in Hong Kong. It is the third road tunnel to cross Victoria Harbour, linking reclaimed land in Yau Ma Tei in West Kowloon with Sai Ying Pun on Hong Kong Island. It was constructed by the Western Harbour Tunnel Company Limited (WHTCL), which also operated the tunnel from 1993 to 2023 under a build-operate-transfer (BOT) model on a 30-year franchise contract with the Hong Kong government. The tunnel was the first three-lane road tunnel in Asia to be constructed using submerged pipe. It was built as part of the Airport Core Programme, which included other infrastructure projects to support the Hong Kong International 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.
