Stonecutters Bridge Detailed Design and Construction of Superstructure

Stonecutters Bridge will span 1018m across Rambler Channel in Hong Kong providing 73.5m high clearance above the busy shipping channel. Due to the typhoon prone environment, detailed design was dominated by the dynamic effects of the turbulent wind loading. Considerable wind tunnel testing was carried out as part of the design process. The high expected percentage of heavy goods vehicles also influenced the design considerably.

High level prestressed concrete decks act as anchor spans to support the steel main span. The concrete back span twin box girders have been constructed in-situ and require a substantial temporary works structure to remain in place until the stay cables are installed. The main span steelwork boxes are fabricated and assembled in China. A 4000T heavy lift scheme for the deck over land precedes main span cantilevering which will take place with 18m long erection segments. Stay cables are prefabricated parallel wire cables up to 540m long.
