Mumbai Metro Rail Corporation (MMRC) accomplished its 39th breakthrough at Mahalaxmi Metro Station out of the 42 breakthroughs planned for the Colaba-Bandra-Seepz underground line, 33.5 km long (line-3), of Mumbai Metro.

Tunnel Boring Machine (TBM), known as Tansa-2, built by the Robbins Company, operated by Doğuş and Soma JV, finished 1,117.5 meters of upline drive of tunnelling from the Science Museum Metro Station to Mahalaxmi Metro Station.

To complete the work, TBM Tansa-2 took 257 days, utilising 745 concrete rings.

Package-3 (Mumbai Central–Worli) consists of Acharya Atre Chowk, Science Museum, Mahalaxmi, Worli Metro stations, and Mumbai Central.It is the longest stretch of the corridor, and out of six breakthroughs planned under this package, it has seen three as of now.

The completed three packages completed are- Science Museum to Mahalaxmi – upline-1117.5m, Science Museum to Worli – upline-2072m, and downline-2057m

By this breakthrough, the total tunnelling finished on the project is 52.60 km out of the 54.50 km double line, around 96.5% of the entire project.

Under Package-3, three more breakthroughs are remaining. The completion of these breakthroughs would mark the end of the tunnelling work on the 33.5 km long fully underground line, including 27 stations on the route.

MMRC, a joint enterprise Indian Government and Maharashtra government, is the nodal firm responsible for implementing the Mumbai Metro Line-3 project.
