    Same with Iron Bridge , located on Holy relics Stream 1 strip of land close to the left bank of river silt Baby , in 11 + 400 kilometers of open road from Hieu Liem ( Eternal ) to Ma Da , the union officials geological 20B detected late 1984, Dong Nai Museum staff , KCH Center and City university of synthesis .
