Tunnel in New Territories, Hong Kong
Tai Lam Tunnel (Chinese: 大欖隧道), running along Tsing Long Highway, is part of Route 3 Country Park Section (R3CPS) and is a transport link between the western New Territories in Ting Kau and Yuen Long.
Tai Lam Tunnel was constructed to ease traffic congestion at Tuen Mun Road, Tate's Cairn Tunnel, and Castle Peak Road. It was also constructed to link traffic directly from New Territories West to urban areas of Kowloon West and Hong Kong Island, the Hong Kong International Airport, and the Kwai Tsing Container Terminals. Located adjacent to the boundary crossings of Lok Ma Chau and Shenzhen Bay, it connects with Shenzhen and Guangzhou for serving both cross-boundary passenger services and cargo logistics.
