The Hong Kong–Zhuhai–Macau Bridge, the world’s longest sea-crossing structure, allows motorists to travel between major cities in about 40 minutes after previously relying on ferry journeys of roughly an hour.
The 55-kilometre (34-mile) bridge links Hong Kong, Zhuhai, and Macau across the Pearl River Delta. Built at a cost of around £15 billion, the project took nine years to complete and is one of China’s most ambitious infrastructure developments.
Designed to strengthen connectivity in the Greater Bay Area, the bridge is intended to boost trade, tourism, and economic integration across the region. It forms part of a wider transport network aimed at linking key urban centres in southern China.
Engineers faced significant challenges during construction, including strong ocean currents, typhoons, and heavy maritime traffic. The structure includes long-span bridges, artificial islands, and tunnel sections to ensure both stability and uninterrupted shipping routes.
Since opening, the bridge has become a vital transport corridor, symbolising China’s push for large-scale infrastructure and improved regional connectivity.
