NHIDCL to build 3 high altitude tunnels
01 Mar 2021
To provide year-round road connectivity with Ladakh through Manali in Himachal Pradesh, work on preparing detailed project reports for constructing tunnels through three high passes beyond Rohtang has been initiated by the National Highways and Infrastructure Development Corporation (NHIDCL). These tunnels are needed as the recent building of the Rohtang Tunnel alone would not improve connectivity between Ladakh and the rest of the country. The three passes beyond Rohtang (13,051 ft) through which tunneling will be done are higher than Rohtang. World’s longest high altitude tunnel of 13.5 km long will be constructed through Shinkun-la which is at a height of 16,703 ft.
