Abstract
Taizhou Bridge is the first kilometer level three-pylon two-span suspension bridge. The middle tower is manufactured by steel with little practical engineering experience. The design and construction of cat walk system is critical to the installation of the superstructures. The design of cat walk system of Taizhou Bridge chosen the continuous four-span structure without anti-wind cables based on the analysis of critical problems of the three-pylon two-span suspension bridge. This paper describes details and construction sequences of the overall design of the cat walk system and the supporting cables, arm rest cable, anchorage system, surface cover, and cross passages, which can be used as references in the similar engineering projects in the near future.
