Hong Kong–Zhuhai–Macao Bridge Inches toward Completion(Part1)

Workers installed the last steel box girder to connect the main bridge of a mega-size sea-crossing project in the Pearl River Estuary early Wednesday, an important milestone reached in just seven years. The project, called Hong Kong–Zhuhai–Macao Bridge (HZMB), will have a total length of about 55 km, including a 6.7 km underwater tunnel and a 23-km bridge over the sea, making it the longest cross-sea bridge in the world. The HZMB authority said that workers started installing the last box girder at 11:45 pm Tuesday, and after one-hour work, it was put into place. The authority said that the construction work of the major part has progressed well. Except for the connection of the main bridge, workers have finished 80 percent of the tunnel construction.

When mentioned to build bridges, it is often needed to build a tunnel. In the tunnel construction, Sinorock® rock bolt has a wide range of applications, such as stabilization of tunnel portals, fore-poling, face stabilization, spilling, root piling and radial systematic anchoring.
