Ba Lin He Bridge

Project description

Carrying the Zheng Shen expressway in Guizhou Province across a deep river gorge, the Ba Lin He Bridge has a main suspension span of 1,088m and a total length of 2.2km. At its highest point the composite deck is 370m above the river. Sidespans are 248m and 228m long respectively.
The crossing was opened in 2008, completing the new expressway link between the towns of Bai Shui and Cheng Guan, and encouraging the development of Guizhou, which is relatively poor compared to China’s coastal provinces.

Four TENSA®MODULAR expansion joints type LR21 were required, with longitudinal movement capacity of 1,680mm. These permit movements and rotations in all three directions. All TENSA®MODULAR expansion joints feature mageba’s ROBO®SLIDE sliding materials, patented asymmetric control system for even gap distribution, and are 100% watertight. An anti-skid coating prevents sliding on the joints when the road is wet. The weight of each expansion joint is approximately 26 tons.
