Ben Hai River was the original demarcation point between North and South Vietnam from 1954 to 1975 and is crossed by the Hien Luong Bridge. The bridge was once symbolically painted in red on the north side and yellow on the southern end, but this ended with the destruction of the bridge during the Vietnam War. In 1973 two flagpoles were constructed, one at each side of the bridge, but the southern one fell over during a storm and was never repaired. On the north side of the Ben Hai rover there is a memorial and an awful lot of water buffaloes, along with a scenic view down the Ben Hai river.
