Гонконг мұнай жолдары: Төртінші өткел және тарифтік саясат

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 and expired on August 7, 2016;
Western Harbour Crossing – a long tunnel between West Kowloon and Sai Ying Pun. Opened 1997. Franchise awarded to a private consortium and expired August 2, 2023.

Prior to the CHT, vehicular traffic used ferry services that began in 1933 and service ceased by HYF in 1998. ( 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 Harbor Crossing (opened September 1989) and the Western Harbor 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.

The fourth harbour crossing is being proposed in Hong Kong as the fourth underwater tunnel to cross the Victoria Harbour to ease the traffic through the Cross Harbour Tunnel. Even though the Western Harbour Crossing, operated by CITIC Pacific Limited, was built for this purpose, the tolls for crossing is triple the rates of the Cross Harbour Tunnel, proving the Western Harbour Crossing ineffective in diverting traffic from the Cross Harbour Tunnel. Around this time, a new tunnel between North Point and Kowloon Bay was suggested to relieve the stress on the Cross Harbour Tunnel. However, the Hong Kong government suffered from the East Asian financial crisis in 1997, and all major projects were put on hold. It was not until 2005 that the topic was brought up again, as the Eastern Harbour Crossing (also operated by CITITC Pacific Limited) announced it would increase its toll prices. It was predicted that 1/3 of traffic from the eastern crossing would use the Cross Harbour Tunnel instead as a result of the price hike, and the influx would certainly be disastrous for the already overloaded tunnel. The call for a fourth tunnel was revived to counter the problem. A new proposal stated that the new crossing would be an immersed tube joining a reclamation site off Hung Hom with Victoria Park in Causeway Bay. The toll booths would be placed at the Kowloon end, and would join Route 5 there. At the Hong Kong Island end there would be a major interchange located under the Victoria Park, connecting with the Island Eastern Corridor. This proposal was deemed the most likely to happen.

HYF, the original car ferry operator continues to use the ferries to transport commercial vehicles on their Dangerous Goods Vehicular Ferry Service routes between North Point, Kwun Tong, and Mui Wo.

A brief car ferry service was operated by Harbour Cruise Bauhinia from the North Point Ferry Pier to Kwun Tong Public Pier in early 2016 to mark the 83rd anniversary of the first car ferry service in Hong Kong.
