Marine technical support for Hong Kong-Zhuhai-Macau Bridge (Hong Kong)

Spanning 55km, the Hong Kong-Zhuhai-Macau Bridge is the world’s longest sea bridge and one of the region’s defining landmarks. BMT helped to address planning and marine traffic issues during the construction phase.

The Hong Kong–Zhuhai–Macau Bridge (HZMB) is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. It is the longest sea crossing on earth and it connects Hong Kong, Macau, and Zhuhai—three major cities on the Pearl River Delta. The Hong Kong section comprises 120 hectares of artificial island and 9km of land and marine viaduct.

BMT provided dedicated marine safety and regulatory expertise to the construction of the Hong Kong Boundary Facilities and the Hong Kong Link Road, which encompasses the eastern bridge structure and the associated reclamation area. We addressed several planning and marine traffic issues such as: maritime-related engineering, ship navigation, marine traffic impact assessment (MTIA) and risk management.

BMT assisted the client in developing specific and well-planned marine schedules, and recommend optimal marine works solutions with the preparation of marine traffic arrangement plans. BMT’s environment experts also provided guidance on the bridge development’s environmental impacts during the construction stage.

BMT’s involvement in the construction of the bridge facilitated the smooth proceedings of the marine works. Following the provision of marine technical support for the eastern bridge structure, BMT subsequently supported the development of infrastructure works at the western portion of the Boundary Crossing Facilities, which involved construction of roads and viaduct connected to the Airport island, that will further link the bridge into Hong Kong’s highway infrastructure.
