Sonamarg Tunnel


The Sonamarg Tunnel is a 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 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, 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 INR1400 billion.

Benefits

The tunnel lies near Gagangir in Ganderbal District of the Indian Union Territory of Jammu and Kashmir, and has great strategic importance for India as it will provide quicker and year-long access to Zoji La. The older road without this tunnel is vulnerable to dangerous snowfall and avalanches, which necessitates its closure for several months in a year. The Z-Morh Tunnel, along with Zoji-La Tunnel located 325km west towards Leh, will ensure uninterrupted connection between Srinagar and Kargil. The completion of the Z-Morh tunnel will also significantly reduce the travel time between Srinagar and Leh as commuters will no longer need to stay overnight in Kargil to compete the trip.
The tunnel will increase social and economic development throughout the region and boost tourism in Sonamarg, which boasts attractions including the Thajiwas Glacier and activities such as whitewater rafting on the Sind River.

Development and construction agency

Initially, the Z-Morh Tunnel was a 450 million dollar project being executed under PPP by Srinagar-Sonamarg Tunnelway Limited, an Infrastructure Leasing & Financial Services owned company which was also the concessionaire for the project.
Earlier, the project was envisaged to be implemented by the BRO as owner and nodal agency. However, it was later transferred to NHIDCL for implementation.
ITNL was appointed as the EPC contractor, which in turn appointed Apco - Titan as a construction contractor for the project. The work was suspended by the construction contractor in July 2018 due to the financial stress of the concessionaire.
The Project Authority foreclosed the concession the agreement/contract with Srinagar Sonamarg Tunnelway Limited and reinvited bidding for the construction of the balance work in June 2019. The revised Total Project Cost stood at ₹2,378 crore. The work was required to be completed in 42 months from the appointed date.
In August 2019, Apco Infratech emerged as the lowest bidder in the International Bidding Process, and in December 2019, the Project Authority issued a Letter of Award for the project.
For the development and construction of this PPP project based on an Annuity-based concession, Apco Infratech floated a project-specific Special Purpose Vehicle : Apco Shri Amarnathji Tunnelway Private Limited.
In January 2019, the Concession Agreement between ASATPL and authority was executed, and 24 June 2020 was declared as the contract start date. In July 2020 it was reported the project will be completed as of 2021.
Apco Infratech executed all the EPC work. M/s Amberg was appointed as the tunnel designer and the approach road design work was given to Transys.
