Chenani-Nashri Tunnel in India- Tunnel support

by Una S. Website Marketing Specialist

Chenani-Nashri Tunnel, in Udhampur, India, is the longest road tunnel project in the country when opened for traffic in 2016. This 9km-long tunnel was built at the foot of the Himalayan mountains, connected the districts of Chenani and Nashri, and its construction cost was 37.2 billion Indian rupees (723 million US dollars).


It is a part of the four-lane widening of the National Highway 1A between Srinagar and Jammu. The tunnel has acted as an alternative to the existing NH1A section, which faced safety concerns, as it passed through steep mountain terrains. The two-line bi-directional traffic tunnel is an all-weather and reliable road throughout the year. It reduces the traveling distance from 41km to 10km.


Another 8.45km tunnel between Quazigund and Banihal on the Jammu-Srinagar highway already completed constructed as part of INR100billion ($2.2billion) road projects in Jammu and Kashmir. It has run in the lower Himalayan mountain range to connect Chenani to Nashri villages.


Construction uses a professional Tunneling technique method to excavate and support. Hollow anchor bolt adopts different materials and processing methods to adapt to all kinds of projects. It combines drilling, grouting and anchoring together, which can bond hollow anchor bolt with surrounding stratum and support the project tightly. Self-drilling anchor bolt support has become an important form of tunnel construction support.
