On September 28, the Quang Binh Department of Transport announced a restriction on vehicle weight across the Thai River Bridge on Provincial Road 558B, Quang Trach District.
Thai River Bridge (located in Quang Phu and Quang Kim communes) was built in 1996. The bridge is 180m long, with 6 spans, each span is arranged with 3 regular reinforced concrete beams, with a design load of H10-X60.
After nearly 30 years of use, the bridge has now degraded and is quite seriously damaged. The concrete of the pier body has peeled off, especially at pier T4 and T5, the concrete layer has peeled off, exposing the rusted steel bars. Because the bridge is located in a saline area, the steel bars are corroding very quickly.
At the bridge abutment, the reinforced mortar rubble has been severely eroded, all the mortar has been washed away, leaving only rubble. The bridge surface is also peeling and cracking, and the expansion joints made of reinforced rubber have been damaged.
Although the management unit has increased regular repairs and maintenance, due to saltwater intrusion, the level of damage to the bridge's items shows signs of further development.
Speaking with VietNamNet, Mr. Chu Viet Dung, Chairman of the People's Committee of Quang Kim commune, said that the Thai River bridge is located on the inter-commune road of Quang Phu, Quang Kim and Quang Hop.
“This bridge is very important. About 14,000 people in Quang Kim and Quang Hop communes who want to go to Quang Phu commune or to National Highway 1A or to the district center must go through this bridge.
Recently, the Department of Transport has sent documents to districts and communes to limit load capacity, and also made propaganda signs, not allowing vehicles with a load capacity of over 5 tons to pass through," said Mr. Dung.
It is known that to prevent the case of collapse, causing accidents due to vehicles with loads exceeding the bridge's load capacity, the Department of Transport has announced that the total weight of vehicles allowed to cross the bridge must not exceed 5 tons, the distance between vehicles when crossing the bridge must be 100m or more (only 1 vehicle on the bridge).
Authorities have installed 2.5m height restriction frames at both ends of the bridge and signs according to current road sign standards.
Vehicles with a total weight greater than 5 tons and a height greater than 2.5m can move along other suitable traffic routes in the area, starting from 12:00 on September 27.
