Abstract

Bridges in the mountainous land of Iran as structures with indigenous architecture have existed since prehistoric times. Crossing the permanent and abundant rivers of Lorestan, which flow in deep valleys, was not easy without using a bridge. Several remaining inscriptions at the site of several historical bridges in Lorestan are evidence of this claim that Badr ibn Ḥasanwayh in the fourth century AH had repaired and rebuilt huge bridges on the rivers of Lorestan, especially the Kashkan River. Therefore, the aim of this research is to introduce one of the important water structures in the Zagros basin and to read and understand the common indigenous techniques of bridge building in this period based on historical documents and evidence, through library and field studies using an interpretive approach and a qualitative strategy. The research, focusing on 4 case studies, while achieving the main framework of the common physical structure of the mentioned bridges, identified the reading of their indigenous techniques and knowledge, which included the technology of building foundations, the similarity of the passage surface and walkway, and the indigenous technique of wide arches in wide spans.
