ErdoX Snow units installation in multiples lines in the avalanche formation zone at the approach road to the Main South Portal
Atal Tunnel, Rohtang is the world’s longest highway tunnel situated at a high altitude of over 3,000m above mean sea level and built on an extremely challenging Himalayan terrain. The tunnel is prone to many natural hazards such as cloud bursts, earthquakes, landslides, rockfalls and avalanches.
The approach road to the main south portal (MSP) has been susceptible to avalanches which can cause considerable harm to the people and infrastructure. In line with the objective to achieve road connectivity throughout the year, Avalanche protection measures using flexible Snow Umbrella units also known as ErdoX Snow units have been undertaken by Maccaferri for Border Roads Organization. These are self-stable metallic structures in a pyramid shape, light weight, easy to transport and quick to install. ErdoX Snow units retain the accumulated snowpack, thus preventing the initiation of an avalanche.
