Zhaoqing

On the morning of Nov 12, the main arches of the Xijiang Bridge on the Naning-Guangzhou railway in Zhaoqing, Guangdong province, were joined together after three years of construction.

Xijiang Bridge is located in the upstream of Sanrong Gorge. The bridge floor is 73.5 meters from the apex of the arch. It spans 450 meters, and is the longest railway arch bridge in terms of span length in the world.

The bridge is China's first mid-height, steel box deck arch bridge for railways, according to Zhang Chunxin, deputy general manager of China Zhongtie Major Bridge Engineering Group, contractor of the project.

Liu Chengliang, chief engineer of the Nanning-Guangzhou railway NGZ-8 project, said the bridge is 618.3 meters in full length. It will be completed by the end of next year. "The construction team is speeding up to finish the tail-in work after the arch is joined," Liu said. "The bridge floor is to be installed next month."

Nanning-Guangzhou railway is a key project listed in the nation's Mid and Long-term Plan for Railway Network Construction and the 11th Five-Year Plan for railways. It is a double-line electrified railway for passenger and cargo transportation, connecting Guangdong and Guangxi. Trains on the railway are designed to run at a minimum speed of 200 kilometers per hour. It will take about three hours to travel from Guangzhou to Nanning, saving 11 hours.
