The Bridge

The Dehang Grand Canyon in Hunan province, China, is crossed by a bridge that connects two tunnels 1,500m apart in the hillsides 336m above the valley floor. The steel suspension bridge has a traditional lattice truss deck.

The bridge and associated road project have significantly cut the travel times across the mountainous region.
