There are three vehicular harbour crossings in Hong Kong, linking the Kowloon peninsula with Hong Kong Island. These are as follows: * Cross-Harbour Tunnel – a long tunnel between Hung Hom and Causeway Bay. Opened 1972. Government owned; franchise expired 1999; * Eastern Harbour Crossing – a long tunnel between Cha Kwo Ling and Quarry Bay. Opened 1989. Franchise awarded to a private consortium until August 2016; * Western Harbour Crossing – a long tunnel between West Kowloon and Sai Ying Pun. Opened 1997. Franchise awarded to a private consortium until August 2023. == History == Prior to the CHT, vehicular traffic used ferry services. This earliest road tunnel, now government owned, opened in 1972. Increasing population and improving prosperity made the construction of further tunnels a necessity. The Eastern Harbour Crossing (opened September 1989) and the Western Harbour Crossing (opened 1997) were subsequently built across Victoria Harbour to ease the burden on the Cross-Harbour Tunnel. For all three tunnels, the government opted for a 30-year private-sector franchise based on a build–operate–transfer model. Two reasons include the less convenient locations of the other two tunnels compared with the Cross-Harbour Tunnel, and more importantly the control of new tunnels by the powerful state-owned investment group CITIC Pacific. The tolls for crossing each of the other two tunnels are significantly higher, and were further increased in 2005 by up to 67% to boost investment returns. Another possible reason for added traffic is induced demand, a theory in transportation planning which posits that the more roads that are created, the more people will choose to commute by car. In this case, by adding additional tunnels, it may have encouraged more people to drive overall, because of a perception that there is increased road capacity. The Government of Hong Kong granted the franchises by enacting legislation that also fixed the revenue and fare model of the tunnel and is thus powerless to prevent the sharp increase in tolls despite public uproar when toll increases were applied for. The Government states public buses (which are usually 90% full) cause congestion.〔("5 coordination of different transport modes" ).
