Transport Infrastructure

Existing Road and Rail Network

At the end of 1998, Hong Kong had 1 865 kilometres of roads and 1 737 highway structures, three immersed-tube, cross-harbour tunnels, and eight road tunnels penetrating the hills of the territory. These facilities provide a comprehensive road network for Hong Kong.

The government owns six of the road tunnels - Lion Rock, Aberdeen, Airport, Shing Mun, Tseung Kwan O and Cheung Tsing - which are managed and operated by private companies under management contracts. Tolls are set and monitored by the government while the Airport Tunnel and Cheung Tsing Tunnel are free of charge.

The Lion Rock Tunnel, linking Kowloon and Sha Tin, began single-tube operation in 1967, with a second tube added in 1978. The 1.4-kilometre tunnel is the most heavily used government tunnel, with 95 000 vehicle trips daily. The toll was $6.

The Aberdeen Tunnel, opened in 1982, links the northern and southern parts of Hong Kong Island. It measures 1.9 kilometres and was used by 58 000 vehicles daily in 1998. The toll was $5.

The toll-free Airport Tunnel between Hung Hom and Kowloon Bay passes under the former site of Hong Kong International Airport at Kai Tak and was opened in 1982. It measures 1.3 kilometres and was used by 55 000 vehicles daily in 1998.

The Shing Mun Tunnel between Sha Tin and Tsuen Wan was opened in 1990 and measures 2.6 kilometres. An average of 54 000 vehicles each day paid the $5 toll in 1998.

The 900-metre Tseung Kwan O Tunnel, opened in 1990, links Kowloon and Tseung Kwan O new town. It was used by 55 000 vehicles daily in 1998. The toll was $3.

The toll-free, 1.6-kilometre Cheung Tsing Tunnel was opened in 1997 and links Kwai Chung and Tsing Yi. It was used by 90 000 vehicles daily in 1998.

The Cross-Harbour Tunnel, the Eastern Harbour Crossing, the Tate's Cairn Tunnel, the Western Harbour Crossing and the Tai Lam Tunnel were built by the private sector under 'build, Operate and Transfer' franchises.

The 1.9-kilometre Cross-Harbour Tunnel connects Causeway Bay on Hong Kong Island and Hung Hom in Kowloon. Opened in 1972, its daily patronage was 120 000 vehicles in 1998. It is one of the world's busiest four-lane road tunnels. The tolls, which included a government passage tax, ranged from $4 to $30 for different types of vehicles.

The Eastern Harbour Crossing was opened in 1989. It links Quarry Bay on Hong Kong Island and Cha Kwo Ling in Kowloon. A daily average of 71 000 vehicles used the two-kilometre tunnel in 1998. Tolls ranged from $8 to $45.

The Tate's Cairn Tunnel was opened to traffic in 1991, providing an additional direct road link between the north-eastern New Territories and Kowloon. At 3.9 kilometres, it is the longest road tunnel in Hong Kong. It was used by an average of 65 000 vehicles daily in 1998. Tolls ranged from $8 to $20.

The two-kilometre Western Harbour Crossing is the first six-lane cross-harbour road tunnel in Hong Kong. Opened in 1997, it links Sai Ying Pun on Hong Kong Island and the West Kowloon Reclamation near Yau Ma Tei in Kowloon. It was used by an average of 33 000 vehicles daily in 1998. Tolls ranged from $15 to $95.

The Tai Lam Tunnel measures 3.8 kilometres and, together with the 6.3-kilometre Yuen Long Approach Road, forms the Route 3 (Country Park Section) which extends from Ting Kau to Au Tau. Opened in May 1998, it was used by an average of 29 000 vehicles daily in 1998. Tolls ranged from $10 to $60.

Besides the network of road tunnels and highways, railways also form a vital part of Hong Kong's transport network. Hong Kong's rail system comprises a heavily utilised urban railway (the Mass Transit Railway - MTR), a busy suburban railway (the Kowloon-Canton Railway - KCR), and the Light Rail (LR). There is also a tramway serving as a local distributor on the northern shore of the Hong Kong Island and a funicular tramway running between Central (Garden Road) and the Peak.

New Roads and Railways Opened in 1997/1998

The relocation of the airport to Chek Lap Kok and the development of the Tung Chung new town required additional road links between Lantau and the urban areas. A new expressway system comprising the North Lantau Highway, Lantau Link, Cheung Tsing Highway, Cheung Tsing Tunnel, Tsing Kwai Highway, West Kowloon Highway and Western Harbour Crossing, was opened to traffic in mid 1997. In May 1998, the expressway system was augmented by the completion of the Ting Kau Bridge and the Route 3 (Country Park Section), which provided easy access to the North-West New Territories.

The strategic expressway system to Lantau and North-West New Territories needs to be carefully managed to ensure smooth traffic flow. Route 3 (Country Park Section) is managed and operated by the private sector franchisee. The Tsing Ma Control Area (TMCA), a 17-kilometre expressway network comprising Tsing Kwai Highway, Cheung Tsing Tunnel, Cheung Tsing Highway, North-West Tsing Yi Interchange, Lantau Link, Ting Kau Bridge and part of North Lantau Highway, is operated and maintained by a private management contractor. TMCA is equipped with extensive traffic control and surveillance system. The system provides a high degree of automation to regulate traffic flows, to assist in dealing with incidents and to provide useful information to motorists.

A one-way toll collection arrangement is adopted for the TMCA. Vehicles travelling on the Lantau Link will be charged twice the single journey toll when they return from Lantau Island. The double toll ranges from $20 to $80.

The $34 billion Airport Railway is an integral part of the transport links to connect the urban areas with the new airport and the Tung Chung new town. It comprises two services-the Airport Express Line and the Tung Chung Line. They were completed and opened to the public on June 22 and July 6, 1998, respectively. The Airport Express Line (AEL) provides a dedicated express rail service for passengers to and from the new airport. Running at a maximum speed of 135 kilometres per hour, the AEL carried about 22 000 passengers each day in 1998 with a journey time of about 23 minutes. It is the world's first purpose-built railway serving an airport with in-town check-in facilities. The Tung Chung Line (TCL) provides commuter services between Tung Chung new town and the urban areas. The TCL carried 110 000 passengers daily in 1998 with interchange facilities with other MTR lines at Hong Kong and Lai King.

New Railway Projects

After the completion of airport related transport network, the government is embarking on the planning and implementation of five new railway projects. Total investment in these projects amounts to some $120 billion. They are:

The 30.5-kilometre West Rail (Phase I), that connects West Kowloon and Tuen Mun via Yuen Long. Construction started in October 1998 for completion by the end of 2003;

The 12.5-kilometre Tseung Kwan O Extension, that extends the MTR from Lam Tin to Tseung Kwan O. The project is expected to be completed by the end of 2002;

The 11.4-kilometre Ma On Shan to Tai Wai rail link, that connects the existing KCR Tai Wai station and Lee On in the Ma On Shan new town;

The 1.5-kilometre Tsim Sha Tsui (TST) Extension, that extends the KCR from the existing Hung Hom terminus to a new station in TST East. Construction is expected to start in 2000 for completion in 2004; and

The 7.5-kilometre Sheung Shui to Lok Ma Chau spur line, that will connect the KCR at Sheung Shui with a new passenger rail boundary crossing at Lok Ma Chau. The government has invited the Kowloon-Canton Railway Corporation to prepare detailed proposals for implementing the project, which is scheduled for completion in 2004.

The Second Railway Development Study

The Second Railway Development Study (RDS-2) began in March. It aims to formulate a clear, coherent and comprehensive strategy for the provision of an integrated and environmentally friendly rail system to sustain the economic, social, land and housing developments of Hong Kong in the years ahead. New projects to be examined in the RDS-2 include the West Rail (Phase II), the East Kowloon Line, a fourth cross-harbour rail link, the North Hong Kong Island Line, a second connection from the Ma On Shan railway to the urban areas and the West Hong Kong Island Line. The study will be completed in September 1999, with interim recommendations on the most urgent projects before then.

Road Projects Under Construction

The construction of the Hung Hom Bypass and Princess Margaret Road Link started in March 1996. This will connect Hung Hom and Tsim Sha Tsui East with a system of elevated roads linking with Princess Margaret Road and Chatham Road. Upon its completion in 1999, the strategic link will provide access to the developments in the Hung Hom Bay reclamation and relieve traffic congestion at the Cross-Harbour Tunnel approach road.

To improve the junction between Hiram's Highway and Clear Water Bay Road, the construction of Phase II of the Hiram's Highway improvement works started in January 1997 for completion in 2000. Phase III of the works in Nam Wai and Ho Chung is scheduled to start in early 1999 for completion in 2001.

Improvement works to Castle Peak Road from Siu Lam to So Kwun Tan started in February 1997 for completion in late 1999. To further improve the road network to the new airport, construction of the Tsing Yi North Coastal Road is scheduled to start in January 1999 for completion in 2002.

Planned Road Projects

To further expand and improve Hong Kong's road network to cope with traffic demand, several strategic road projects are currently under study and design.

The eight-kilometre section of Route 7 connecting Kennedy Town to Aberdeen will provide a much-needed linkage to the southern part of Hong Kong to support the strategic development of the area.

Route 10 will run about 27.5 kilometres from Hong Kong Island to the North-West New Territories via North Lantau. Together with the planned Deep Bay Link, it will form part of the proposed crossing between Hong Kong and Shekou in Shenzhen. Route 10 will also relieve the traffic burden of the Lantau Link, and maintain road access to Lantau in the event that the Lantau Link has to be closed under inclement weather or emergencies.

Route 9 (section between Cheung Sha Wan and Sha Tin) will be a new 5.6-kilometre highway running from Sha Tin to West Kowloon. It will significantly alleviate traffic congestion at the Lion Rock Tunnel, Tate's Cairn Tunnel and Tai Po Road.

Other major new road projects under planning include the Central Kowloon Route between To Kwa Wan and Yau Ma Tei, the Central-Wan Chai Bypass and another section of Route 9 connecting Tsing Yi and Cheung Sha Wan.

Environmental Considerations

The environmental impact of new transport projects during both the construction and operation phases is carefully examined at the planning stage. Environmental mitigation measures, such as landscaping, artificial contouring of surrounding hillsides, the installation of noise barriers and noise insulation works are implemented where necessary to minimise the environmental impact of transport projects.

Road Opening Works

Besides serving as carriageways for vehicles and pedestrians, roads also accommodate various utility services, such as water and gas mains, sewers and electricity and telephone cables. To cope with the increasing demand for utility services and maintenance work, utility companies often have to excavate the carriageways and footpaths to lay more pipes, cables and ducts, and to carry out repair work. There were about 150 new road openings on each day in 1998. Road openings are co-ordinated and controlled by the Highways Department through a permit system, under which utility companies are required to carry out work to a required standard and within a time limit.

To co-ordinate work more effectively and to minimise traffic disruption the Highways Department holds monthly Road Opening Co-ordinating Committee meetings with the utility companies, the police and the Transport Department. A computerised utility management system was developed in 1997 to further improve co-ordination and minimise disturbance to road users.
