Amid the country's latest push to increase the operating mileage of railways, constructors from China Railway No 4 Engineering Group have completed building the nation's first large-span rod-tied arch bridge with cable suspension on a high-speed railway.
The 443.1-meter railway bridge, traversing the Yingshan-Dazhou Expressway in the prefecture-level city of Dazhou in Sichuan province, consists of three parallel bridges — a main bridge on the Xi'an-Chongqing High-Speed Railway, as well as the left and right connecting bridges.
The whole bridge has been built in three stages. The first was completed on July 11, 2025, with the main arch bridge measuring 147 meters in length, weighing 2,600 metric tons and being 17 meters wide. The second stage, the left link bridge, was completed on Dec 17, 2025, and weighs 1,531 tons, which is 136 meters in length and 11.4 meters wide. The third stage, the right link bridge, has now been completed and weighs 1,531 tons. It is 136 meters in length and 11.4 meters wide.
