World's widest immersed channel takes shape

The first tube of the world's widest immersed channel is expected to be put in position of a mega bridge across the Lingding Bay at the mouth of the Pearl River in South China soon, according to an assistant chief engineer of the project.

Yang Runlai from CCCC First Harbor Engineering Co Ltd said Thursday that workers are preparing for the connection of a tunnel end on an island with the first immersed tube, the Science and Technology Daily reported.

Yang's company took charge of constructing an island and major part of the tunnel of the Shenzhen-Zhongshan Bridge, another mega project of bridge, island and tunnel after the Hong Kong-Zhuhai-Macao Bridge (HZMB).

The new project, 38 kilometers from the HZMB, is 24 kilometers long. It has the immersed tunnel in the east and the bridge section in the west to ensure the sea routes there.
