Kabir Kouh Tunnel is an ongoing road tunnel project in Ilam Province, Iran. The tunnel passes under the Kabir Kouh range connecting the counties of Darreh Shahr and Abdanan, shortening the current 40abbr=NaNabbr= mountain pass to about 6 km. Kabir Kouh is a 170abbr=NaNabbr= long mountain range in Ilam Province extending along a southeast-northwest axis from an area near Pa Alam, Lorestan Province to the vicinity of Chenar Bashi about 20km (10miles) south of Ilam. The range acts as a barrier between the province's western areas such as Abdanan and border cities of Mehran and Dehloran with the country's internal road networks.

The tunnel eliminates the 40-km Kabir Kouh Mountain Pass which reaches as high as 1700m (5,600feet) above sea level at its peak and consists of hundreds of hairpin turns.

The project consists of a 4750abbr=NaNabbr= main tunnel and eight other shorter tunnels with a total length of 1500m (4,900feet) connecting the Darreh Shahr-Pole Dokhtar route to the main tunnel.

The construction of the tunnel started in May 2010 and was planned to be opened in four years.[1] As of August 2019, the main and connecting tunnels have been dug but the project is yet to be completed.[2] [3]
