Z-Morh Tunnel

The Sonamarg Tunnel (Hindi) is a 6.5-kilometre-long (4.0 mi) road tunnel connecting Gagangir and Sonamarg in Ganderbal district of Jammu and Kashmir, India. It carries two lanes of National Highway 1. It bypasses a Z-shaped stretch of road, which used to be avalanche-prone and get blocked during the winter months due to heavy snowfall. However, now the tunnel provides all-weather connectivity to Sonamarg. It takes only 15 minutes to travel the 6.5 kilometres (4.0 mi) long tunnel compared to hours over the previous zig-zag road. Together with the adjacent Zoji-La Tunnel, this geostrategically important tunnel provides year-round all-weather connectivity to Baltal (Amarnath cave), Kargil and other places in Ladakh, enhances Indian military logistics and boosts tourism and local economy. It is one of 31 road tunnels, 20 in J&K and 11 in Ladakh, constructed at a combined cost of ₹1.4 lakh crore (~US$17.5 billion).
