The old Dezful Bridge was constructed during the Sassanid era, and accounts for one of the ancient bridges in the world. At present this bridge connects Dezful and Andimeshk cities. It has been repaired several times during the reign of Azedodowleh Daylami, the Safavid, Qajar and early Pahlavi periods.
The bridge currently has four large arches, and between every two of these is a smaller arch. Near the bridge, remnants of ancient mills can be observed.
