Description
Description | The Hong Kong-Zhuhai-Macau Bridge (HZMB) is the world's largest sea-crossing bridge-and-tunnel system, spanning 34 miles. Designed to last over a century with a cost of $18.8 billion, it includes three cable-stayed bridges, an undersea tunnel, and four artificial islands. The bridge features 215,278 square feet of engineered bamboo panels on its artificial islands, which have withstood extreme weather conditions including sun exposure, seawater corrosion, and typhoons since its opening in 2018. Innovations in bamboo processing have enhanced durability and sustainability of the materials used. |
