The Harbour Tunnel is a major road tunnel located in Hong Kong, connecting the Hong Kong Island and the Kowloon peninsula. Opened in 1989, it provides a vital transportation link for vehicles, helping to ease traffic congestion in the area. The tunnel is approximately 1.8 kilometers long and is part of the Route 2 highway system. The Harbour Tunnel features a toll system, which helps maintain the infrastructure and manage traffic flow. It is one of several tunnels in the region, including the Cross-Harbour Tunnel and the Eastern Harbour Crossing, all of which contribute to the efficient movement of people and goods across the Victoria Harbour.
