A simple but beautifully proportioned concrete arch bridge, Zhenzhu is part of a new group of mid-sized concrete arch bridges in Western China.
The difficult location required the engineers to build the two halves of the arch vertically on hinges before lowering them down where they were joined at the crown. Zhenzhu was built on a new bypass road that avoids the older descent into the river gorge.
