The sea-crossing bridge with the largest span in China -- the Shuangyumen Bridge in the eastern coastal province of Zhejiang -- has seen a key progress in its construction, with the pouring of concrete for its first main bearing platform completed on Thursday.

It marks the official start of the tower pillars for this world-class bridge, which is part of the the Ningbo-Zhoushan Port Liuheng Highways and Bridges project.

The pouring of concrete was completed at 11:00 on Thursday, following arduous efforts for more than 30 consecutive hours.

The circular platform is 26 meters in diameter and 7 meters in height. The concrete of platform and tower were cast in three steps, with a total designed volume of 8,888 cubic meters.

The rebars of the platform and the tower are epoxy coated , in order to ensure the durability of the bridge structure in the strongly corrosive seawater.

"During the processing and installation of epoxy coated steel bars (rebars), we need to pay special attention to the protection of the coating, and we need to re-coat the damaged parts in time, so as to meet design requirements and make steel bars erosion-resisting," said Sha Renming, head of the second working area of the Liuheng Highways and Bridges project, which is contracted by the China Railway Construction Corporation (CRCC).

As a key control project of the second phase of the Liuheng Highways and Bridges project, the Shuangyumen Bridge connects the two independent islands of Liuheng and Fodu in Zhoushan City of Zhejiang, with a main span (center to center distance of adjacent towers) of 1,768 meters.

"After the completion of the project, the traveling time between Liuheng and Ningbo will be shortened from 70 minutes by boat to 10 minutes by car, ending the history of no road connection between Liuheng, Fodu and Meishan," said Yuan Mingguang, a project manager of the bridge construction at CRCC.

Construction of the Shuangyumen Bridge is expected to be completed in 2027. After the bridge opens to traffic, it will effectively improve the traffic conditions of the southern islands of Zhoushan. The bridge is also an important project for the implementation of the Belt and Road Initiative (BRI) and the Yangtze River Economic Belt strategy.
