Spanning 55 kilometers, the Hong Kong-Zhuhai-Macao Bridge is an integrated bridge-island-tunnel mega-project recognized as one of the "Seven Wonders of the Modern World." The project features two 100,000-square-meter artificial islands and a 6.7-kilometer immersed tube tunnel that holds multiple world records. Completion of the project has significantly improved regional connectivity, seamlessly bringing Hong Kong, Macao, and Guangdong into a one-hour commuting circle.
