A single Cabinet decision on Tuesday, 27 October 2026 is set to redraw the commute map for hundreds of thousands of people across the Mumbai Metropolitan Region. Maharashtra Chief Minister Devendra Fadnavis chaired the Cabinet Committee on Infrastructure meeting at Mantralaya, Mumbai and secured approval for Mumbai Metro Line 12A — an 18.40 km fully elevated corridor that will finally stitch together Kalyan-Dombivli and Navi Mumbai by rail.

What Metro Line 12A Actually Builds

The corridor will run from Manpada-Katai Naka to Taloja via Kalyan Phata, threading through one of the Mumbai Metropolitan Region's most congested and industrially significant belts. 12 stations are proposed along the alignment. What makes this project structurally distinct is its integration with an elevated roadway: the corridor embeds a 6.93 km four-lane flyover section and an 8.69 km six-lane section — a combined road-rail spine rather than a standalone metro track.

The project is projected to serve approximately 4.74 lakh passengers daily once operational, with officials estimating a travel-time reduction of 40–50 per cent compared to current road journeys on the same route. Fadnavis directed that the project be delivered within three and a half years — a firm, publicly stated deadline that will be the first test of execution.

Taloja, Kalyan-Dombivli and the Industrial Connectivity Gap

Taloja, located in Navi Mumbai, is one of Maharashtra's significant industrial and logistics clusters — home to manufacturing units, warehousing facilities, and a dense workforce that currently relies almost entirely on road transport. The lack of a direct rail link to Kalyan-Dombivli, a twin-city residential hub with a combined population in the millions, has long been flagged as a drag on both labour mobility and freight efficiency. Metro Line 12A closes that gap directly.

For daily commuters, the arithmetic is blunt: a journey that crawls through congested state highways could be cut nearly in half. That is not just a convenience — it reshapes where workers can realistically live relative to where they work.

Fadnavis's Push to Accelerate All Maharashtra Metro Projects

The Line 12A approval was not the only directive to come out of Tuesday's meeting. Fadnavis specifically emphasised that all ongoing metro projects across Maharashtra must be accelerated to ensure timely completion — a signal that the state government is treating the broader metro network, not just individual corridors, as a political and governance priority heading into the next phase of the state's infrastructure push.

Deputy Chief Minister Eknath Shinde, Deputy Chief Minister Sunetra Pawar, and Minister Chandrashekhar Bawankule were present at the meeting alongside senior officials — a full-weight Cabinet presence that underlines the political significance attached to the approval.

Maharashtra has been expanding its metro network through the MMRDA master plan across multiple corridors since the early 2010s, with Mumbai Metro Line 1 — operational since 2014 — setting the template for elevated alignments in the region. Line 12A continues that model while adding the integrated flyover component as a force-multiplier for road traffic alongside.

The next pressure points are real: tendering, land acquisition, and coordination with MMRDA will determine whether the three-and-a-half-year clock holds. The CM has set the target publicly. The infrastructure machine now has to match it.
