A truck drives over a makeshift bridge supported by ruined tanks on the road north of the Salang Tunnel in Baghlan province, August 31, 2002. High in the mountains of the Hindu Kush, the road was destroyed several years ago by a flood from raging mountain rivers. The road was improved by the Soviets after their 1979 invasion of Afghanistan, and was a crucial link for troops and supplies coming from the Soviet Union. The mountain road is in terrible condition, and its repair is crucially important for the reconstruction of the country
