Construction of Shanghai-Nantong Railway River-spanning Bridge, the world's first super long-span cable-stayed highway-railway combined bridge of above a thousand-meter, has made a breakthrough progress until January 21, 2017. The two sections of the special shipping channel bridge for Port of Tiansheng have jointed smoothly. It is proud that the bridge steel with the domestic highest strength Q500qE used at the key part of the bridge was supplied by Ansteel.
