Shapoori Bridge (Tagh-e Pil-Eshkesah)
Shapoori Bridge is located in southern Khorram- Abad. It has been used to connect the western part of Lorestan (Tarhan) to the east, and then on to Khoozestan province and Taysafun, the capital city of the Sassanian. The bridge is 312 meters long and 10.75 meters high. It has 28 arches and 27 piles. The area of each pile is 61 square meters, and the distance between the two piles is 7.5 meters. Five of its arches are intact; the others have been destroyed by natural factors. The arches of the bridge are made in the form of a wishbone. The piles and breakwaters of the bridge are in the form of six lateral lozenges made of stone. Probably the bridge also was used to distribute water. Materials of the bridge are river stones and stone chips in the arches and truncated stones in the piles. The bridge floor is paved in red block stones that have lost their square shape due to erosion. This attractive, huge bridge belongs to Sassanian era, and it is registered as number 1058 in the list of Iranian national monuments.
