Lingdingyang Bridge completes aerial construction channel

On April 22, the Lingdingyang Bridge catwalk of the Shenzhen-Zhongshan Link was completed, marking the completion of the construction of the bridge's aerial construction channel.

The catwalk is a temporary construction access road erected under the main cable and parallel to the main cable during the construction of the suspension bridge. It is a high-altitude construction platform for the operation of the upper structure of the suspension bridge.

There is a catwalk under the main cables on the left and right sides of the Lingdingyang Bridge, connecting the east and west main towers of the bridge. The catwalk is about 4.1 meters wide, and the total length of a single piece is about 3,000 meters.

The Lingdingyang Bridge is one of the key projects of the link, with a main span of 1,666 meters and a main tower height of 270 meters, which is equivalent to a 90-floor-building. It is the world's highest sea-crossing bridge.

The Shenzhen-Zhongshan Link is a super sea-crossing project integrating "bridges, islands, tunnels, and underwater channels." The total length of the link is about 24 kilometers.
