The steel truss deck of the New Tongyang Canal Bridge was successfully closed
updated on :2019-12-06 08:55

After months of construction around the clock, on the afternoon of Dec 2, with two large floating cranes smoothly hoisting the last steel girder bridge deck, the steel truss deck of the main bridge of the New Tongyang Canal Bridge was successfully closed. It was an important node of the north extension of the east ring expressway project, achieving a big step forward to the goal of linking up the whole line of the project.


The bridge is the first double-deck highway bridge in Taizhou. Different from the traditional concrete bridge, the steel structure of the main bridge is not cast in the construction site, but produced in sections by a professional factory according to the design scheme and connected with high-strength bolts. The technical difficulty of this project lies in the high precision of hoisting and assembling of the double-layer structure, the on-water operation as well as the complicated construction technology. The total weight of the steel truss structure is 4600 tons, which is rare among bridges in Jiangsu province.
