The highest bridge in the world is 98ft long & 18,379ft high above sea level

The Bailey Bridge is the highest bridge in the world in terms of altitude. 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 just 30 meters (98 ft) long, and is at an altitude of 5,602 meters (18,379 ft) above sea level. 
The Bailey bridge system was devised by British engineer Sir Donald Bailey during World War 2, and consists of a basic diamond braced unit of welded steel, which can be easily manipulated by a squad of six men and joined together to make complex bridging structures. 

The Bailey Bridge is a portable pre-fabricated truss bridge, designed for use by military engineering units to bridge up to 60m (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.
Don’t confuse this with the bridge that stands highest over water. This accolade goes to the Royal Gorge Bridge that lies over the Arkansas River, Colorado. This one dates back to 1929 at a cost of $350,000 and spans 321 m (1,053 ft) above the water.
