Infrastructure
Roads
Eyvan is on Road 17 (Iran). The Eyvan-Ilam part, which has recently been expanded into a four-lane road, is the busiest road in Ilam province.[10] The Eyvan-Ilam route has one tunnel, the Payambare Azam, 1,480 meters long and inaugurated in February 2010. The 50-km Eyvan-Ilam route was made 11 km shorter, replacing the old Renu Tunnel.[11] The Eyvan bypass project is planned to be completed in two years.
There are two secondary roads; the older is to Sumar and the newer to Gilan-e Gharb.[12] Eyvan was connected to Gilan-e Gharb by a new route through Nawdar Road in 2015, making the distance between the two cities 40 minutes shorter.[13][14][15]
