The Hong Kong – Zhuhai – Macao Bridge (HZMB)

The Hong Kong – Zhuhai – Macao Bridge (HZMB), straddled across Lingdingyang of Pearl River Estuary, linking the Hong Kong Special Administrative Region (HKSAR), Zhuhai City of Guangdong Province and Macao Special Administrative Region. The total length is about 42km, counting from the Hong Kong Boundary Crossing Facilities at the east to the Zhuhai/Macao Boundary Crossing Facilities at the west. The uniqueness of the project includes:

The HZMB will be the longest bridge-cum-tunnel sea-crossing with dual 3-lane carriageway, which is about 35.6km in length from the shore of northern Lantau to the western shore of Pearl River Estuary.

The HZMB is to be built with 120 years design life. The design and construction standard not only need to satisfy the requirements stated in Mainland’s relevant regulations and the feasibility study report, but also suitably taking into account Hong Kong and Macao Standards.

The HZMB construction environment is complicated. Frequent typhoons, crisscross navigation, airport height restrictions, high environmental standards, etc should be taken into considerations.

To minimize the impact of the bridge design to river flow, navigation and hydrology, there is stringent requirement to control the water blockage ratio during the selection of options.
