Stonecutters Bridge

The cable-stayed bridge is a new landmark of Hong Kong with fan-shaped white cables and world's second largest center span.

The Stonecutters Bridge is a highway bridge that spans the 900-m-wide Rambler Channel in Hong Kong. The total length is 1,596 m. The cable-stayed bridge has a center span of 1,018 m, the world's second largest. A total of 224 cables (28 levels and eight planes) were used in the center and side spans. Parallel wire strand (PWS) cables have been adopted to resist wind load. A clearance of 73.5 m is available under the deck to enable large container ships to pass. The main pylon is 298 m tall. The completion of the bridge revitalized the communication between the Hong Kong International Airport and the city center.
Cables with a maximum length of 540 m and a maximum weight of 77 t. Measures taken on the surface to control vibrations during the rain.

In order to ensure safe construction of bridge decks at sea, bridge decks were first constructed on side spans and then decks were launched to the center span. A steel deck segment on the center span weighed approximately 600 tons. Segments were hoisted using a lifting stand and fixed while maintaining balance. Segments were lifted by wires extended from the main pylon and welded to existing segments.
