Work on two key Metro corridors linking Mumbai’s western and eastern suburbs via Bandra-Kurla Complex (BKC) and the airport has been accelerated, with the Mumbai Metropolitan Region Development Authority (MMRDA) pushing parallel progress on track installation and station systems, even as civil structures are still being completed. The move is aimed at cutting execution timelines and avoiding last-mile delays on Metro Lines 2B and 7A, both of which are critical for cross-city connectivity and airport access.

‘I think they are expanding Line 2B to Chembur, and it will be very useful when the Monorail starts operating. And for 7A, it is a perfect airport connection for all’
Arindam Mahapatra, Commuter
‘With the tenders out for track laying at this stage, MMRDA should plan accordingly about completing the girder launching in the remaining areas at Kurla and BKC so that by the time girder launching is completed, track installation can start immediately and provide some relief to office goers heading to BKC’
Yash Mhadgut, Infra enthusiast
‘It’s great that tracks are being laid for Line 7A and Line 2B, as both lines are crucial for interchanges. Line 7A will allow direct transfer from Red Line to Aqua Line, and Line 2B will connect the western suburbs, BKC and the eastern suburbs directly. Navi Mumbai connection will become easier via Line 2B through Mankhurd station’
