UNDATED (CNN) -- A temporary steel trestle bridge has been broken and washed away on Thursday by flood water resulted from the torrential rain that hit central china's Hunan Province on Wednesday night.
The heavy rain began to fall in Jianghua Yao Autonomous County, Yongzhou, at around 22:00 Wednesday night, and caused the water in the local Tuojiang River to rise. The rising water then broke the trestle bridge used to convey building materials for the under-construction Tuojiang River Bridge on the next morning.
The ruined steel trestle bridge was three meters high and weighed 170 tons. It had been submerged in the flood water for less than one hour before it was completely flooded away. The steel pole that was one meter above the water was then flooded shortly after.
The damage of the steel trestle bridge brought the construction of the Taojiang River Bridge to a stop, which could cause a delay in the overall construction time of the bridge, according to Dai Dejun, chief engineer of Tuojiang River Bridge.
The flood also caused the temporary widening of the river. Some boats were forced to pull aside and the transit between the two banks was suspended too. Some residential houses and streets on the riversides were also submerged by flood water.
The Centianhe Reservoir in Jianghua County opened five water gates at their full capacity to release the flood water in the river at 21:00 that evening. The water flow reached more than 3,300 cubic meters per second.
Residents were transferred to safe places after the heavy rain began to fall, and no casualties have been reported so far.
