The signing ceremony for the supply of steel truss for Yueyang Dongting Lake Bridge on Inner Mongolia-Jiangxi railways in central China was held at the bridge project office recently. CRBBG won the bid for fabrication of 23,063 tons of steel box girders and steel truss girders combination for the bridge.

Located at Yueyang city, Hunan province, Yueyang Dongting Lake Bridge is one of the key control projects of Inner Mongolia-Jiangxi railways in central China. The bridge has an overall length of 10,444.66 meters, designed for double-track railway with the running speed of 120 km/h and the distance between tracks of 4.2 meters. It is composed of three parts, three-tower cable-stayed steel box and truss girder bridge, 92-meter steel pipe and concrete tied-arch bridge at Junshan bank, and 84-meter simply supported steel truss girders at Yueyang bank, and the total weight of the project is up to 23,063 tons. In which, the main bridge, with 98+140+406+406+140+98 meters span, is a three-tower double cable plane cable-stayed bridge of a combination of steel box girders and steel truss girders. The main tower is reinforced concrete structure with a height of 157 meters, and it is inverted Y-shape above the bridge deck and turns inward to diamond shape below the deck. For the main bridge, the center to center distance of top chord of the main truss is 12 meters and of lower chord 14 meters. The main girder adopts Warren truss without vertical members, and two sets of main truss are configurated transversely, with the total width of 21 meters, height of truss 12 meters, panel length 14 meters, and elevation slope of web member 59.744 degrees. The bridge is made up of 92 panels and the Q370qE steels are used for the major structure.

It is reported that the Inner Mongolia-Jiangxi railways in central China for coal transportation is a new strategic transport corridor for the "North-to-South coal transport" in China, as well as the major transportation infrastructure in the national 12th Five-Year Plan and the major project of the 12th Five-Year railway plan. It starts from Erdos of Inner Mongolia in north China, where enriched with coal resources, via Shaanxi, Shanxi and Henan, and enters into Hubei, Hunan and Jiangxi where deficient in coal resources. The line has an overall length of about 1,750 km and is constructed according to the standard of national railway level I and double-track electrified railway. The estimated traffic volume for short term is 100 million tons and for long term above 200 million tons.
