Sujiaba Bridge in Chongqing features unique spiral design

The Sujiaba Bridge in Chongqing, China, has become a notable landmark due to its unique spiral design. Reaching heights of approximately 72 meters—equivalent to a building with over 20 floors—the elevated road creates a sensation for drivers of ascending into the air.

The spiral configuration was engineered to address the significant topographical challenges of Chongqing, specifically the large elevation differences in the region. The bridge serves a practical purpose by connecting the Caiyuanba Yangtze River Bridge to Haitong Road, which sits at a much lower altitude.

Beyond its functional role in the city's complex network of over 300 elevated passages and bridges, the Sujiaba Bridge has attracted tourist interest. An outdoor observatory and viewing corridor have been established nearby, allowing residents and visitors to observe the multi-layered construction and the city skyline.
