The Kabul – Salang – Doshi Highway Rehabilitation Project comprises a 75 km section of the 175 km highway within scope of the rehabilitation of the Main Transportation Artery of Afghanistan. The project was designed as a two-way, single-lane highway, with each lane being 3.5 m wide. The superstructure of the road consists of a hot asphalt coating. Since it is a rehabilitation project, the construction of the road was realized in two different types; one in the form of new construction and the other as a correcting layer on the existing road. Construction works concerning 360.000 tons of foundation / substratum and 135.000 tons of hot mixture coating were completed.

The rehabilitation construction of the 2.7 km long Salang Tunnel, which connects Kabul to the northern part of Afghanistan, was also completed within the scope of this project. A total of 290 km long snow tunnels were constructed through the passage of the Hindikush Mountains and the maintenance and repair of the existing snow tunnels were completed. Rehabilitation / extension works of 150 culverts, the construction of 25 new ones and three new steel beamed, 45 m wide bridges and maintenance and repair works of 12 existing bridges were also completed as part of the project. Transportation has become much more comfortable along this route, which is utilized by approximately 1.500 vehicles everyday, and the duration of travel between Kabul and Doshi has been reduced to two hours.
