Description

The Hangzhou Bay Bridge stands as a monumental achievement in engineering, representing China’s commitment to innovation and infrastructure development. This remarkable structure is the world’s longest cross-sea bridge, uniquely designed and built through China’s own investment and management. The bridge is constructed to withstand the challenges posed by large tidal ranges and severe storms in Hangzhou Bay, an area characterized by unprecedented scour depths. With no existing precedent for a bridge of this type, the design team, comprised of experts with extensive experience in structural feasibility, successfully addressed numerous technical challenges through rigorous trial and error.

Designed for a lifespan of over 100 years, the Hangzhou Bay Bridge incorporates cutting-edge technology tailored to the specific hydrogeological conditions of the region. Its elegant S-shaped curve, inspired by the scenic West Lake in Hangzhou, harmoniously blends functionality with aesthetics, serving both transportation and tourism needs. The construction process alone witnessed over 250 technical innovations, culminating in nine independent core technology series, marking a significant milestone in the global history of cross-sea bridge construction.
