The Mumbai Metro Rail Corporation Ltd, which oversees the 33.5 km Metro-3 project, has already spent over Rs 19,000 crore in tunnelling, civil works, station work and track-laying. About 23 per cent of the construction work was completed at Aarey (before work was stayed there), while no work took place at the Kanjurmarg site, said an official from the MMRCL.
