Anzob Pass is a high mountain pass, at an elevation of 3.372 metres (11,062ft) above the sea level, located northwest of Tajikistan's capital Dushanbe. The pass is traversed by M34 highway.The pass is located on the main road between Dushanbe and Samarkand and there’s a weather observation station located at the pass top.
The last 20km averaging 7-8% in gradient and the road up and over Anzob Pass is narrow, muddy and without a safety rail - you'll feel like leaning into the car and away from the edge, even with the safe experienced hands of your Pamiri driver behind the wheel.
The pass is opened to regular traffic in the last week of May. Then the pass is closed, and people take a tunnel below the summit, called Anzob Tunnel, or "The Tunnel of Death", with a length of 5km. The tunnel floor is a maze of deep, seriously deep, potholes hidden under a constant stream of water, the tunnel is strewn with abandoned construction machines and filled with the no. xious black smoke of clapped out lorries. The poisonous air in the tunnel is barely shifted by one solitary fan somewhere in the middle of the tunnel, which gives some, but not sufficient movement to the air. There are no traffic lights to regulate traffic through this section, nor is there an ordered tidal flow of traffic being allowed to enter the tunnel, instead anarchy prevails in the darkness. The tunnel was completed in 2006.
The pass is one of the most treacherous mountain passes of Central Asia. On October 23, 1997, an avalanche killed 46 people, burying 15 trucks and cars. The avalanche was so large that it took two weeks for the would-be rescuers to reach the victims. Some road sections may require a high clearance 4WD vehicle, in four-wheel-drive, driven by a driver experienced in 4WD drive techniques to drive the road without getting stuck.
