The Ting Kau Bridge (Chinese汀 九 桥/汀 九 桥) is a 1,177 -meter long cable-stayed bridge in Hong Kong, the island extends to Tuen Mun Road in Tsuen Wan District of the North West Tsing Yi. It is located within sight of the Tsing Ma Bridge, which serves as a vital link to the Hong Kong International Airport and Lantau Island. The bridge was completed in 1998. They can be crossed free of charge.

Infrastructure

The bridge is one of many infrastructure projects as part of the new building of the international airport at Chek Lap Kok, which is located about 30 kilometers from Hong Kong Iceland north of Lantau Island. Together with the Tsing Ma Bridge and Kap Shui Mun Bridge results in the countryside of Hong Kong an interesting panorama on the way from downtown to the airport. The Ting Kau Bridge has the highest traffic of the three bridges mentioned. Here drive along many trucks between the home country of China and the container port of Hong Kong. A special color matching and adapted to the architectural lighting lift out the bridge from their environment.

Design and special features

The Ting Kau Bridge was the first major cable-stayed bridge with three pylons and four main fields worldwide. The pylons have heights of 170 meters on Ting Kau side, 194 meters on an artificial island 158 meters above sea level on the north west coast of Tsing Yi. The design of the pylons is another special feature of the building. Due to high wind loads by typhoons, these are designed as slender, guyed masts. In the transverse direction, the stabilization by ropes and trans verse takes place, similar to the Mastabspannung with sailboats. In the longitudinal direction of the intermediate principal pylon has, in addition to the stay cables to the longitudinal stabilization, which combines the pylon top with the floor beams to the adjacent pylons.

The 42.8 -meter wide main bridge has to improve the wind stability two by a 5.26 meter wide gap to separate, 18.77 meters wide superstructures, which are each suspended on two wire planes. The 1.75 meter tall superstructures have a composite cross section consists of a 24 cm thick deck slab of reinforced concrete components and the longitudinal and transverse beams.

The Ting Kau Bridge and its approach bridges connect the western New Territories, an administrative district in Hong Kong, with the home country of China towards a highway called " Lantau Fixed Crossing" ( also briefly Lantau Link ), which the new airport with Kowloon and Hong Kong Iceland connects. The junction point is located just 500 meters from the Tsing Ma Bridge on the island of Tsing Yi. The bridge with approach spans a total length of 1,875 meters of which the main bridge occupies 1,177 meters. The bridge crosses the Rambler Channel, which has a width of about 900 meters. Each driving direction has three lanes and the usual fall protection equipment.

Costs

The planning and total cost amounted to 1.94 billion Hong Kong dollars. The bridge is one of the world's longest of this type. Together with the Tsing Ma Bridge and Kap Shui Mun Bridge of them is monitored continuously with the Wind and Structural Health Monitoring System ( WASHMS ).

Planning and construction

The bridge was designed and built by the Ting Kau Conctractors joint venture between 1994 and 1998. The joint venture consisted of Cubiertas Y Mzov ( 22%), Entrecanales Y Tavora (22% ), both from Spain and parts of Acciona SA, Züblin (22%) from Germany, Downer & Co. (22%) from Australia and Paul Y ( 12%) from Hong Kong. The planning and construction management was Schlaich Berger and Partner from Stuttgart.
