evidence: The Chenani-Nashri tunnel project included the construction of an underground tunnel, two bridges, toll plazas, 1.3 km of approach road toward the south portal, 0.6 km of approach road towards the north portal, all project facilities, and spoil dumps. [...] The drill and blast tunneling method was used for the construction of the Chenani-Nashri tunnel. The section was mainly sub-divided into heading (top portion of the tunnel) and benching (bottom portion of the tunnel) for excavating through hard rock faces. In contrast, the mechanical excavators were used for excavating through the shear zones and weak rock mass. [...] The construction of the Chenani-Nashri tunnel was started in 2011. Both the main and escape tunnels were constructed simultaneously from the south and north end of the Chenani and Nashri village, respectively and construction was completed in 2016.
