Design concept of the Twin River Bridges in Chongqing, China

Man-Chung TANG

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4, Pages 427-431 doi: 10.1007/s11709-011-0134-6

Abstract: The Dongshuimen Bridge over the Yangtze River and the Qiansimen Bridge over the Jialing River in Chongqing, China are located at the tip of the Yuzhong Peninsula. Together, they are called the Twin River Bridges. Both are double deck structures carrying four lanes of traffic on their upper decks and two transit tracks on their lower decks. The girders are steel truss structures with orthotropic plates and the towers are made of concrete. Aesthetics were carefully considered for the design of these bridges because of their visibility in the city and their neighboring landmarks.
