The construction of the Atal Tunnel connecting Manali with Leh, which is the world's longest highway tunnel above 10,000 feet, has been completed in a span of 10 years. The horseshoe shaped single-tube, double-lane tunnel has many firsts. It is also the country's first tunnel to have an escape tunnel within the main tunnel because of the topography. This is also the first tunnel to deploy the Rowa flyer technology, which allows engineers to work at inverted levels.
