China's Aizhai Bridge - world's highest and longest tunnel-to-tunnel bridge 矮寨大桥

The Aizhai Bridge (矮寨大桥) is a suspension bridge on the G65 Baotou–Maoming Expressway near Jishou, Hunan, China.

With a main span of 1,146 meters and a deck height of 350 meters, it is the sixth-highest bridge in the world and the world's twelfth-longest suspension bridge. Of the world's 400 or so highest bridges, none has a main span as long as Aizhai. It is also the world's highest and longest tunnel-to-tunnel bridge.

Construction on the Aizhai Bridge began in October 2007 and was completed by the end of 2011, ahead of schedule.The bridge was temporarily opened to pedestrians during the 2012 Spring Festival and was formally opened to traffic in March 2012.

The bridge was built with the assistance of a $208 million loan from the Asian Development Bank; the loan also funded 64 kilometers of expressway construction and upgrades to 129 kilometers of local roads. The bridge and the associated road construction reduced the travel time between Jishou and Chadong from 4 hours to less than 1 hour.
