On July 4, the construction of ballastless track of Quanzhou Bay sea crossing bridge of the newly-built Fuzhou Xiamen railway, the first cross sea high-speed railway bridge in China, created favorable conditions for the subsequent track laying and opening to traffic. The newly-built Fuzhou Xiamen railway is located in the coastal area of Fujian Province, starting from Fuzhou in the north to Xiamen and Zhangzhou in the south. The main line is 277.42 kilometers long, with a design speed of 350 kilometers per hour. The whole line is expected to be put into operation in 2023.
