This paper describes the design process of the rail bridge crossing the Jialing River in Caijia area. In the main bridge section, the paper focuses on light rail's functional requirements, structural design of the cable-stayed bridge, construction monitoring, structural health monitoring system, as well as maintenance requirements. In the approach span section, it introduces several features such as tall pier, large span, width change, and horizontal curve. Movable scaffolding system has been used for construction of the approach spans. This bridge provides valuable experience in design and construction for similar projects in the future. © 2012 Taylor & Francis Group. Source

The Chongqing Caiyuanba Yangtze River Bridge, located in the core area of the city, is a longspan bridge built for dual highway and rail traffic, the main span of which is a combined rigid frame-tied arch bridge of 420m long, which is the world's longest span among bridges of the same kind. The bridge carries six lanes of highway and two pedestrian walkways on its upper deck as well as double-line urban light rails on its lower deck. The design of the bridge adheres to the principle of "safe, innovative, cost effective" and features innovative design concepts and technologies, which helps to merge the bridge structure's safety, functionality, economy and the bridge aesthetics into one natural manner. The hybrid structure of combined prestressed concrete rigid frame and steel box tied arch is applied in the bridge scheme to improve both span capacity and efficiency of material use. The combination of orthotropic steel plate and steel truss girder is used to carry highway and rail transit loads. This paper describes overview of the project, bridge schematic design as well as detailed structural design. © 2012 Taylor & Francis Group. Source

Dongshuimen Yangtze River Bridge and Qiansimen Jialing River Bridge, together be called the Twin River Bridges, are designed to carry two tracks of light rail transit and four lanes of highway traffic through three business districts of Chongqing, China. The actual weight of the trains and their intended configuration of the rail transit are used for the design of the bridges. The main spans of these two bridges are 445 m and 318 m, respectively. This article describes the special provisions of the specifications for the design of this dual-function bridge, and the special devices used for light rail transit operations. Source
