TSING YI BRIDGE

This brief article gives an outline of the planning and construction of the bridge which will link Ising Yi Island to the Chinese mainland at the Kowloon penninsula, Hong Kong. This bridge will serve motor traffic and accommodate electricty cables and oil and other service pipes. A post tensioned reinforced concrete bridge design on the principle of balanced canitilevers was chosen in preference to a suspension bridge because of the prevalence of typhoons, five 200 ft. cantilevers giving four spans of 400 ft and two of 200 ft. After describing the negotiations that preceded construction, the author gives some details of the construction of the piers and of the structure itself. He also describes the precautions that were necessitated by the prevalence of tyhoons. The bridge is the second longest of its type in the world. The consultants, contractors, engineers and others who participated in the project are cited.
