Kandovan Tunnel | The Story of Karaj–Chalus Road. Iran’s Historic Path Through the Alborz Mountains

Описание: The Kandovan Tunnel is one of Iran’s greatest engineering achievements — a monumental gateway carved through the mighty Alborz Mountains along the legendary Karaj–Chalus Road (Road 59).

Built during the reign of Reza Shah the Great, this tunnel stands as a testament to human determination and vision. Constructed entirely with basic tools like shovels and pickaxes, its completion in 1938 transformed travel between Tehran and Mazandaran, cutting the route by 13 kilometers and ending months of seasonal isolation.

Once the longest tunnel in the world, Kandovan not only connected north and south but also symbolized Iran’s journey toward modernization.
