Cross-Harbour Tunnel

The Cross-Harbour Tunnel (香港海底隧道), or "XHT" in short, is the first tunnel in Hong Kong that was built under water.

Opened in 1972, the Cross Harbour Tunnel provided a road link between Kowloon and Hong Kong Island making it possible to drive directly to and from the island. With the tunnel linking the main financial districts on both sides of Victoria Harbour it became the busiest route in Hong Kong with over 100,000 vehicles using it daily. Until August 1999 it was administered by the Cross Harbour Tunnel Company before reverting back to government control.
