Dragon Bridge is the 6th bridge and the newest bridge across the Han River. Because the bridge is shaped like a dragon, it is called the Dragon Bridge
Dragon Bridge is 666m long and 37.5m wide with 6 lanes running. It was started construction on July 19, 2007, officially opened to traffic on March 29, 2013. The cost of constructing the bridge is nearly VND 1.5 trillion (US $ 88m). The bridge was designed by Ammann & Whitney Consulting Engineers with Louis Berger Group. The construction is carried out by Civil Works Construction Corporation 1.
This modern bridge crosses the Han River at the Le Dinh Duong / Bach Dang roundabout. Create the shortest path from Danang International Airport to major roads in Danang City. And a direct route to My Khe beach, Non Nuoc beach east of the city. The bridge was designed and built in the shape of a dragon, capable of spraying fire and sprinkling like real life.
Currently, the time for fire and water spraying starts at 21:00 on Saturdays, Sundays and major holidays.
Ability to fire and spray water
By design, the dragon on the bridge can spray fire for two minutes, followed by 3 minutes water spray. Make Dragon Bridge has become an impressive, unique and attractive highlight in Da Nang City.
At the request of Da Nang city leader on fire spraying:
Must interrupt spray, forming each halo with a diameter of 2-3 meters and away from 8-10 meters, the halo must reach high aesthetics, harmony with the environment landscape, absolutely no damage to surfaces and structures of structures. The fire must spray at an angle of 15-45 degrees, upwards from the vertical of the bridge and there is no ash or oil falling. Oil is completely burned, creating fire and smoke; Convenient for operation, maintenance and maintenance; The equipment must be modern, absolutely safe, able to work in different weather conditions …
In fact, during a test spray on March 6, 2013, it sprayed 9 fireballs with the diameter of each fireball reaching from 3 to 4 meters and the halo went from 10 to 15 meters. Through experimental measurements, the bridge in a show night, consumed 54-81 liters of oil and about 2kWh of electricity for spraying fire. The total cost at that time was from VND 2 million to VND 2.5 million. In the future, the system of fire-fighting equipment will be improved in the style of “Dragon with a pearl”. When spitting fire, the front half of the gem will open. When finished spraying, the gemstone will automatically close.
Spraying water is not like burning fire. The cost for a night of water spray Dragon (3 minutes) only cost about 200 to 250 thousand VND according to the price of the time tested. One spray (3 minutes) requires 20m3 of water and 40kWh of electricity. The Dragon did not spray the dense water stream but sprayed the water into a very strong, beautiful steam, expressing the desire to reach out to Da Nang. To do this, the bridge is designed to contain 20 cubic meters of water, 325 cubic meters of compressed air. Produces tens of thousands of cubic meters of steam and water spraying with a flow rate of 1,944 l / s.
The bridge has a total investment of up to 1498 billion 684 million VND (about 80 million USD)
