The initial cause was assessed as subsidence of the soil under the anchor bar on the right side of the M2 abutment, causing the anchor bar to move, pulling down the cable pillar, causing the entire bridge to collapse.
Like Dan tri reported that at around 1:20 p.m. on the same day, the Ke Ninh suspension bridge over the Hieu River, connecting the two villages of Ke Ninh and Dinh Tien (Chau Hanh commune) suddenly collapsed.
At the scene of the bridge’s complete collapse, the stay cables, steel frame and concrete panels were on the mudflats, and part of the bridge structure was on the riverbed.
The incident fortunately did not cause any human damage. A buffalo belonging to people grazing on the mudflats under the bridge died.
According to the design, the bridge has a total length of 237m, width of 2.4m, load capacity of 2.5 tons, and the bridge deck is made of reinforced concrete. The road connecting the two ends of the bridge is designed according to rural traffic class A, with a 5m roadbed and a 3.5m wide road surface made of 250 grade concrete, 20cm thick.
