The World’s Longest Bridge over the Sea 5,000th Pre-cast Bridge Segment Completed!

Part of the massive Hong Kong Zhuhai-Macao Bridge (HZMB) project, Dragages Hong Kong and VSL have been joining hands to design and construct this 9.4-km long dual three-lane viaduct section. Upon the completion of this new land transport link, commuters will take only some 45 minutes to reach Zhuhai from the Hong Kong Airport – compared to 4 hours at present.

This pre-cast segmental bridge with the world’s longest span of 180m is being constructed with 5,714 pcs of pre-cast segments. To cope with the complex bridge alignment, more than 250 different types of segments are produced in various dimensions and sometimes unsymmetrical.

On 19^th September, our project team members, together with management teams from the HZMB HK Project Management Office and the segment provider (CCCC2), celebrated the production of the 5,000^th segments and completion of all segment-on-pier (SOP) parts. The celebration was held on site in the segment factory located in the mainland.
