Mumbai, July 21: The Mumbai Metro Rail Corporation (MMRC), implementing agency of the underground Metro Line 3 (Colaba--Bandra--SEEPZ) has attained 39th breakthrough at Mahalaxmi station on Wednesday. Robbins made TBM Tansa-2 completed its upline drive of 1117.5 meters from Science Museum Metro Station to Mahalaxmi Metro Station in 257 days using 745 concrete rings.
