建设中的京沪高速铁路和京广客运专线铁路，跨长江、黄河的4座大跨度桥梁都采用了钢桁梁结构，且均为多线铁路桥或公铁两用大桥，承载能力大、列车运行速度高。诸多新材料、新结构、新工艺获得运用。

The steel truss structure is adopted for all of these bridges of the under construction Beijng-Shanghai and Beijing-Guangzhou High Speed Railways across Yangtze River and Yellow River, and they are multy railway lines or rail-cum-road bridges, with heavy loading capacity and high railway operation speeds. Some new materials, new structures and new workmanship are applied accordingly.
