Rishikesh-Karnaprayag Rail Line Project Progresses With Final Breakthrough Of Shrinagar-Dungripanth Main Tunnel

In a major milestone, the final breakthrough of the main tunnel connecting Shrinagar and Dungripanth on the Rishikesh-Karnaprayag rail line was achieved on Tuesday (21 January).

This tunnel, known as Tunnel Number 11, spans from GITI Maidan in Srinagar to Dungaripanth and measures a total length of 9.05 km.

On Tuesday, a breakthrough was achieved at the 3.3-km mark, successfully connecting both ends.

The Rishikesh-Karnaprayag Rail Line Project is a 125-kilometer new broad-gauge railway being constructed by Rail Vikas Nigam Limited (RVNL).

This milestone brings the ambitious Rishikesh-Karnaprayag Rail Line Project closer to its goal of enhancing connectivity in the hilly terrain of Uttarakhand.

Tunnel construction on the project has been divided into 10 distinct packages, each being executed by separate agencies.

Package-6, under which Tunnel Number 11 falls, is located between Government ITI ground in Srinagar and Dungaripanth (Dhari Devi Station Yard).

This 9.05-km-long tunnel will connect Srinagar and Dungaripanth, forming a critical part of the project.

Twin Tunnels for Safety and Efficiency

Tunnel number 11 comprises two parallel tunnels: the main tunnel for train operations and an escape tunnel for emergencies.

To expedite construction, two additional access tunnels, Edit-5 near Shrikot Ganga Nali Gas Godown and Edit-6 in Sweet village, were built.

Portal-1 of the main tunnel is located at G ITI ground, while Portal-2 is at Dungripanth/Dhaari Devi Station Yard.

At 3 pm on Tuesday, the final breakthrough between Portal-1 and Edit-5 was successfully achieved, marking a significant milestone.

With this, the entire 9.05 kilometers of the main tunnel excavation is now complete.

Progress on Final Lining and Supervision

The final concrete lining has already commenced, with 5.29 km of work completed in the main tunnel and 3.6 km in the escape tunnel.

The construction under Package-6 is being executed by Song Da-Ritwik JV, supervised by project management consultant AECOM.
