Highways Upgradation in the Hilly Areas and Its Impact—An Example of Uttarakhand
https://orcid.org/http://orcid.org/0000-0003-2906-1395
Uttarakhand is one of the Himalayan states where a visionary scheme of Government of India was launched in 2016 to widen all the highways totalling to about 900 km (with broad design of two lanes with paved shoulders) leading to Chardhams (Gangotri, Yamnotri, Kedarnath, Badrinath and the Kailash Mansarovar in Tibet). During widening of these highways, multiple kinds of problems related to slope instability and drainage were observed. Ground observations indicate towards the inadequate prior assessment of vulnerability of the slopes to the cutting, methods of the cutting as well as the mitigation and management deficiencies. Most of the highway stretches, therefore, widened so far have been affected by the landslide and like slope processes, and the number has increased multifold compared with the already existed landslides. This indicates towards the lack of planning and understanding about the slope vulnerability; as a result, an opportune chance of constructing a wider, disaster resilient and environmentally safe highway network in very important border state has been missed. This present study will try to highlight the issues which had been addressed prior and during the highway upgradation/modernization and will also discuss the possible rectification in future for risk-free management of the highway.
