The mighty Yangtze River is well over a kilometer wide where it passes through the city of Nanjing, a thriving modern metropolis.
Most of the bridges built across the Yangtze River since the first truss bridge was completed in 1968 are long-span cable-supported structures.
Now another equally impressive structure has been built across the river, the 5th Nanjing Yangtze River Bridge, also known as Nanjing Jiangxinzhou Yangtze River Bridge.
It is a three-tower cable-stayed structure with a main span of 1.2 km and a total length (excluding approaches) of 1.8 km.
The bridge was opened to traffic in December 2020.
After supplying TENSA-MODULAR expansion joints with large movement capacities to the 2nd / 3rd / 4th Nanjing Yangtze River Bridges during the last 20 years, mageba was again selected to be the expansion joints supplier of this latest structure.
Overall, two TENSA-MODULAR LR13 expansion joints were installed at both ends of the structure with a total length of 60 m.
Each of the two modular joints are designed to accommodate longitudinal deck movements of 1,040 mm, as well as transverse and vertical movements and multi-axial rotations.
They were also designed for concreted connections to the bridge’s abutments and welded connections to its steel superstructure, and feature ROBO®GRIP anti-skid coating on their driving surface to enhance vehicle safety.
