The Salang Tunnel (Persian: تونل سالنگ Tūnel-e Sālang) is a 2.67 kilometres (1.66 mi) long tunnel located at the Salang Pass in the Hindu Kush mountains, between the Parwan and Baghlan provinces of Afghanistan. It was completed by the Soviet Union in 1964 and has been used to connect the northern Afghan cities with the capital of Kabul. The tunnel is currently being repaired and improved. Between seven and ten thousand vehicles pass through the tunnel each day.
The Salang Tunnel is the only pass going in a north-south direction to remain in use throughout the year. It is known for a deadly fire which occurred in November 1982, and several avalanche incidents. A series of avalanches led to the deaths of as many as 172 people in February 2010 either as a direct result of the avalanche or through being trapped.
The tunnel represents the major north-south connection in Afghanistan, cutting travel from 72 hours to 10 hours and saving about 300 kilometres (190 mi). It reaches an altitude of about 3,400 metres (11,200 ft) and is 2.6 kilometres (1.6 mi) long. The width and height of the tunnel tube are 7 metres (23 ft). Other sources say that the tunnel is no more than 20 feet (6.1 m) wide at the base and 16 feet (4.9 m) high, but only in the center.
