Aizhai Bridge, Suspension and road bridge in Jishou, Hunan province, China

The Aizhai Bridge carries the G65 Baotou–Maoming Expressway across the DeHang gorge near Jishou, Hunan, at a deck height of 336 metres. Its main span between the pylons is 1,176 metres, while the red-painted truss deck between the two tunnel entrances is 1,000.5 metres long, 27 metres wide and 7.5 metres high. One pylon stands before a tunnel portal, the other on the rock above the opposite tunnel.

Construction of the bridge began in October 2007 and was completed ahead of schedule in late 2011, with the official opening to traffic taking place on March 31, 2012, reducing travel time between Jishou and neighboring areas from four hours to under one hour.

The bridge's name comes from Aizhai, the town it serves in Jishou, Hunan. Visitors can walk through the inside of the red truss deck on a walkway whose floor is partly made of glass panels, looking straight down into the DeHang canyon. In September 2012 the bridge hosted an international BASE jumping festival with more than 40 jumpers from 13 countries.

The deck is a red-painted truss 27 m wide and 7.5 m high, carrying the G65 expressway between two short tunnels. A walkway inside the truss lets visitors cross on foot, and several metres of its floor are glass panels looking down into the DeHang gorge. Drivers approaching cannot see the bridge until they are nearly on it.

The first cable across the DeHang gorge was flown by a small airship, and the deck segments were then moved into place on transport blocks running along horizontal cables hung from the hangers. Because one pylon stands just before a tunnel mouth and the other on the rock above the opposite tunnel, some hangers ahead of the pylons carry no deck and only steady the main cables.
