CHONGQING (CQNEWS) -- The New Baishatuo Yangtze River Bridge connects Dadukou and Jiangjin and is an important channel from Chongqing to Guizhou. Recently, this bridge — with three “world’s first” records — was built up. Let’s have a look.

Set three “world’s first” records

The whole New Baishatuo Yangtze River Bridge is 5.32 kilometers long, with the main bridge being 920 meters long. It is an important passage and critical control work for the Chongqing-Guizhou Railway to cross the Yangtze River.

This bridge sets three “world’s first” records: first six-track railway steel-trussed cable-stayed bridge, first six-track railway steel-trussed cable-stayed bridge with longest span and heaviest load and double-deck railway steel-trussed cable-stayed bridge.

Four-track passenger railway at upper deck and double-track freight railway at lower deck

The double-deck six-track railway bridge includes two tracks for the Chongqing-Guizhou Passenger Railway, two tracks for the Chongqing-Guizhou Freight Railway and two tracks reserved for the Chongqing-Hunan Passenger Railway.

The designed speed of the four-track passenger railway on the upper deck is 200km/h, while that of the double-track freight railway at lower deck is 120km/h. After the Chongqing-Guizhou Railway is opened, it will only take a minimum of 16.56 seconds for trains to pass over the bridge.

Bridge wearing “raincoat” to extend service life

Usually in our impression, only road and highway bridges are paved with asphalt, but this bridge is also paved with asphalt.

This bridge is a steel-trussed cable-stayed bridge. The steel trusses are exposed and easily corroded by acid rain. Therefore, the new-type epoxy asphalt concrete (similar to a “raincoat”) is used to extend the service life of the bridge. (Translated by Huang Juan, Fathom Language Limited)
