The Hong Kong-Zhuhai-Macau Bridge, the longest sea crossing in the world, spans 34 miles across the Pearl River Delta, linking Hong Kong, Zhuhai, and Macau. This monumental structure, completed in October 2018 after nine years of construction at an estimated cost of £15 billion, has drastically reduced travel times from an hour-long ferry ride to approximately 40 minutes by car. The bridge is a key element in enhancing transport connections within the Greater Bay Area, a region targeted by Beijing for economic development. It features multiple long-span bridges and artificial islands, designed to accommodate large vessels while minimizing environmental disruption. The bridge's design includes cable-supported structures with unique towers, ensuring both functionality and aesthetic appeal. Since its inauguration, the bridge has recorded over 10 million trips, demonstrating its significance in improving trade and mobility across the region. The engineering challenges faced during construction, including typhoons and marine conditions, were met with innovative solutions, showcasing China's ambitious infrastructure goals.
