Bailey bridge - World's highest bridge
The Bailey bridge is the highest bridge in the world. It is located in the Ladakh valley between the Dras and Suru rivers in the Himalayan Mountains. It was built by the Indian Army in August 1982. It is 30 meters (98 ft) long, and is at an altitude of 5,602 meters (18,379 ft) above sea level. The Bailey bridge is a portable pre-fabricated truss bridge, designed for use by military engineering units to bridge up to 60 m (200 ft) gaps. It requires no special tools or heavy equipment for construction, the bridge elements are small enough to be carried in trucks, and the bridge is strong enough to carry tanks. A bailey bridge is a prefabricated bridge used by combat engineers, which can be rapidly constructed on the battlefield. The system was devised by British engineer Sir Donald Bailey during World War 2, and consists of a basic diamond braced unit of welded steel, 3×1•5 m/10×5 ft square, which can be easily manipulated by a squad of six men and joined together to make complex bridg...
