PUNE: Maharashtra Metro Rail Corporation (Maha Metro) has completed the construction of first underwater metro tunnel below the Mutha river bed for the Pune Metro Rail Project.

Under Phase-1, Line-1(Purple Line) has an underground stretch of length 5.019 km from Agriculture College to Swargate with 5 underground stations. The work is divided in two packages – Package 1 from Agriculture college to Budhwar Peth and Package 2 from Budhwar Peth to Swargate. Both packages have been awarded to the JV of Tata-Projects-Gulermek.

Two TBM (Tunnel Boring Machines) i.e. S78 (Mutha) and S79 (Mula) were commissioned last month to build twin tunnels. Work on 1.6 km underground tunnel from between Agriculture College and Shivajinagar has been already completed. Tunnel work for the stretch between Civil court to Budhwar Peth started in March. After few days, Maha-Metro entered the riverbed of the Mutha river and now the tunneling work beneath Mutha river bed is completed.
