The world's highest and longest tunnel-to-tunnel bridge has opened to traffic in Hunan province, central China. The Aizhai suspension bridge links two tunnels 1,176 metres apart, carrying traffic 355 metres above the foot of Dehang Canyon. Construction of the bridge started in October 2007 and its main sections were completed at the end of last year. It is designed to help ease traffic in the mountainous region, where queues are common due to the narrow, steep and winding roads.
