A big hole with 1.5 meters diameter and 4 meters deep on October 2 suddenly appeared on the surface of the Ham Luong Bridge, which connects three islands of the southern province of Ben Tre.
The breakdown fortunately did not cause any accident for people and transport. The province transport department blocked the scene and alerted to people.
It also is investigating the cause of the breakdown.
Ham Luong Bridge was opened to traffic on April 24 this year. The 8,216-m bridge, which links Ben Tre City and Mo Cay Bac District, has a span of 150m, the longest span in Viet Nam, and four lanes in a width of 16m.
The bridge, costed at VND787 billion (US$39 million) in total was built by Vietnamese engineers.
