Hong Kong–Zhuhai–Macau Bridge, Bridge-tunnel system in Pearl River Delta, China.
The Hong Kong–Zhuhai–Macau Bridge is a combined bridge and tunnel crossing in the Pearl River Delta linking three major cities. Spanning 34 miles (55 kilometers), it includes three cable-stayed bridges, an undersea tunnel, and four artificial islands built above the water surface.
Construction began in December 2009 and opened to the public in October 2018. The project emerged in response to the growing demand for direct connections between the three coastal regions around the Pearl River Delta.
The crossing has become a symbol of the closer ties linking Hong Kong, Macau and mainland China through Zhuhai. It serves daily commuters, families with connections across these regions, and travelers seeking faster routes between the metropolitan areas.
The crossing cuts travel time between Hong Kong and Zhuhai to around 45 minutes, compared to several hours on alternative routes. Private vehicles need special permits and separate licenses valid on both sides of the border, so most travelers rely on shuttle buses or other public transport options.
The structure holds the record as the longest fixed sea crossing in the world and was engineered to withstand earthquakes of magnitude 8 and typhoons of category 16. The tunnel runs deep below the surface to allow large cargo ships to pass overhead without disruption.
