The Grand Kashkan Bridge, spanning 186 meters, is a concrete structure featuring a composite deck made of precast I-shaped beams and cast-in-place concrete slabs. The bridge is designed with two separate lanes for traffic, each with a width of 11.9 meters, and consists of eight spans of approximately 23 meters each. This bridge was constructed and opened to traffic in 2019, following the destruction of the old Pahlavi Bridge by the floods of April 2019. The Khorramabad-Kuhdasht route, with an overall length of 85 kilometers, passes through a mountainous area and serves as a critical corridor in western Iran, connecting the provinces of Lorestan, Ilam, and Kermanshah. The Kashkan Bridge is located 48 kilometers west of Khorramabad, crossing the Kashkan River.
Given that the old Khorramabad-Chegeni-Kuhdasht road was located in a mountainous area and lacked proper geometric design, with two opposing lanes of very poor quality, it had become one of the most accident-prone routes in the country. The implementation of a four-lane highway, along with the geometric design improvements and elimination of hazardous spots on this route, was considered one of the most essential road projects in the country. The old two-lane road lacked an appropriate geometric design in its horizontal alignment, and significant damage was evident in the asphalt surface of the old road in most areas due to vertical alignment issues. These deficiencies led to problems such as speed limitations, increased road accidents, vehicle wear and tear, and the wastage of national resources.
