On October 22, the main tower of the newly-built Fuzhou-Xiamen (Men) Railway Anhaiwan Bridge was topped off.

This bridge is the first time that a ballastless track has been laid in a sea-crossing cable-stayed bridge in China’s 350km/h high-speed rail construction, realizing the world’s highest speed of sea-crossing high-speed rail bridges-China’s sea-crossing high-speed rail bridge has entered the "350 era".

  Due to technical bottlenecks, most of the domestic high-speed rail long-span bridge designs adopt ballasted tracks, but the flatness of ballasted tracks is limited, and trains must slow down when passing, which affects the ride experience.

The flatness of the ballastless track is extremely high and the stability is strong. The train passes "like on the ground" and the ride experience is stronger.

  It is understood that the Anhaiwan Super Bridge was invested and constructed by the Southeast Coastal Railway Fujian Co., Ltd. and undertaken by the China Railway Construction Bridge Bureau Group.

The bridge is located in Quanzhou City, Fujian Province, connecting Jinjiang City and Nan'an City, with a total length of 9.46 kilometers, of which the sea-crossing section is 1.56 kilometers long. The main bridge is a 650-meter double-tower double-cable-plane steel-concrete composite beam semi-floating system cable-stayed bridge.

As one of the three cross-bay bridges on the Fuxia high-speed rail line, the bridge has a main span of 300 meters and crosses the main channel of Anhai Bay. The main tower is 126.9 meters high. It is a key control project across the line and is expected to be closed in July 2021.
