This bridge on Gheshlagh river is a remnant of Safavids and Zandieh era. It was renovated later, especially by Qajar's dynasty. The bridge was constructed by the order of Shah Safi of Persia, on the route from Sanandaj to Hamedan. Two centuries later, when the bridge was almost ruined, it was renovated again. A stone inscription on the facing mountain reads the name of Gholam Hossein Khan who repaired the bridge.[4][5][6]
