After seven hours of construction, a steel tube arch was installed on the Shangqiu-Hefei-Hangzhou high-speed railway bridge across the Huai river in Anhui province on February 28. The operation will facilitate the completion of the northern section of the railway within this year.

A floating crane lifted the steel arch to the required height before it was fixed atop the structure. According to Xinhua, the construction started at 8:28 am and finished at 3:28 pm.

"Adopting the latest in-situ integral synchronous lifting reduces installation time and ensures that high-speed trains can run at 350 km/h when crossing the bridge, without dropping speed or being hit by turbulence," said Zhu Zhangyi, chief engineer of the project. "The use of Ⅲ type plate rail technology without a frantic jumble has fully independent intellectual property rights, allowing it to become the first rigid-frame arch bridge with a high speed railway track without a frantic jumble in the world."

The Shangqiu-Hefei-Hangzhou railway is one of the largest high-speed railway lines in the 13th five-year plan undertaken by Anhui Jingfu passenger railway co. Ltd, and the Huai river bridge is one of its most important projects.

From Shangqiu in Henan province to Hangzhou in Zhejiang, the railway track designed for a speed of 350 kilometers per hour stretches over 794.55 kilometers and cost 96.08 billion yuan. According to the plan, the northern section of the railway in Anhui province expected to be opened by the end of 2019 will be completed in May this year, with the joint test beginning in September. The railway will be complete by 2020.
