China opens record breaking 4,000 ft long bridge
Aizhai Bridge in Hunan province is 336 m (1,102 ft.) high and has a 1,176 m (3,858 ft.) span.
It connects two traffic tunnels in the mountains, cutting the time needed to traverse the canyon from 30 minutes to 1 minute. Construction took five years.
Work finished at the end of last year, making it the world’s longest and highest suspension bridge.
Note that the person below is 1102 feet above the ground and is sweeping the dirt off this twenty first century engineering marvel with a broom that was designed centuries ago and has no safety line. Blasting and coating this steel superstructure in a couple of decades will be an interesting project.
The bridge, which connects two tunnels, was built to ease traffic. Drivers can take in the views of the Dehang Canyon People and traffic during the opening ceremony. Vehicles motor along a two-way, four-lane motorway.
Pedestrians walk along it on a special walkway under the road.
