MUMBAI, (Metro Rail News): Mumbai Metro Rail Corporation (MMRC) achieved the 39th breakthrough at Mahalaxmi Metro Station on Wednesday out of the total 42 breakthroughs planned for the 33.5 km long Colaba-Bandra-Seepz underground line (Line-3) of Mumbai Metro.
The Robbins Company made TBM (Tunnel Boring Machine), named Tansa-2, operated by Doğuş and Soma JV has completed 1,117.5 meters of upline drive of tunneling from Science Museum Metro Station to Mahalaxmi Metro Station. TBM Tansa-2 took 257 days using 745 concrete rings to finish the breakthrough.
Package-3 (Mumbai Central–Worli) includes five stations namely – Mumbai Central, Mahalaxmi, Science Museum, Acharya Atre Chowk, and Worli Metro stations. It is the longest stretch of the corridor and has now witnessed a total of three breakthroughs out of six breakthroughs planned under this package. The three breakthroughs which are completed are – (Science Museum to Worli – upline-2072m and downline-2057m) and (Science Museum to Mahalaxmi – upline-1117.5m).
Three more breakthroughs are remaining, all under Package-3, finishing of these breakthroughs will mark the completion of the tunneling work on this 33.5 km long fully underground line with 27 stations on the route.
“This was indeed a challenging task as this particular stretch encompasses tunneling below the buildings that are more than 80 years old and live western railway track between Mahalaxmi and Lower Parel Station. Our team has accomplished this tough task efficiently,” said Mr. Ranjit Singh Deol, Managing Director, MMRC.
With this breakthrough, the overall tunneling completed on the project is 52.60 km out of the total 54.50 km double line which is approximately 96.5 % of the total project.
Mumbai Metro Line-3 (Colaba-Bandra-SEEPZ) is a 33.5 km long fully underground line with 27 stations which would connect 06 business districts, 30 educational institutes, 30 recreational facilities, and domestic as well as international airport terminals. It will have a total of five interchange points for the suburban railway and one each for Monorail and ‘Versova-Andheri-Ghatkopar’ Line-1.
MMRC, a joint venture of the Govt. of India and the Government of Maharashtra, is the nodal agency responsible for the implementation of the Mumbai Metro Line-3 project.
