Researchers from the Vietnam Archaeology Institute and the Museum of Cao Bang Province said that the vaulted bridge, which is 4.75m long and 2.46m wide is almost intact. It was built from large slabs of stone with lime and honey.

According to scripts on a stone stele erected in 1831 about 10m from and end of the bridge, the bridge was built in the time of King Le Canh Hung (1740-1786) and then repaired during the reign of King Minh Mang.

An ancient stone bridge dated back to the Le Dynasty has been found in Coc Khoac Hamlet, Tra Linh District, northern border Cao Bang Province.
