Namma Metro Phase 3: Route Map, New Stations, & What it Means for Bangalore Real Estate

Namma Metro Phase 3 real estate impact is significant – due to expanding rail connectivity across western, southern, and northern Bangalore.

Namma Metro Phase 3 will add two elevated corridors covering 44.65km and 31 stations. The 32.15km Orange Line will run from J P Nagar 4^th Phase in the south to Kempapura in the north along the western stretch of Outer Ring Road (ORR). The 12.5km Grey Line will connect Hosahalli with Kadabagere along Magadi Road – in the west.

The Orange and Blue lines will provide complete metro coverage around the entire Outer Ring Road, and create a full corridor encircling the city.

Namma Metro route map shows interchange points with existing and upcoming lines, linking major commercial and residential hubs. These will impact rental demand, land use, and location choices among homebuyers and investors.

Namma Metro Phase 3 at a Glance (2026)

Phase 3 vs Phase 3A: Clearing the Confusion

These form two distinct parts of the city’s rapid transit expansion. Phase 3 received Union Cabinet approval on 16 Aug 2024, and comprises the J P Nagar 4^th Phase Kempapura and Hosahalli Kadabagere stretches. Its foundation was laid on 10 Aug 2025.

Bangalore Metro Phase 3A refers to the proposed Sarjapur Hebbal Red Line, which received Karnataka govt sanction in Dec 2024 – and is awaiting Union govt clearance following design and cost revisions. The ‘A’ suffix identifies an additional package under the third expansion stage, not a subdivision of the approved Phase 3.

The city’s overall expansion includes distinct alignments, including the route covered in the Hosur Bommasandra Metro Yellow Line guide, which serves the southern industrial belt.

Together, the packages cover ~18.6km: J P Nagar 4^th Phase to Kamakya Junction, Hoskerehalli to Nagarabhavi Circle, and Vinayaka Layout to BDA Complex Nagarbhavi, including Sunkadakatte station and depot links.

Work associated with Magadi Road metro near Sunkadakatte forms part of the initial tender package. Each contract carries an execution period of 1460 days. Contractor selection and preparatory activity will determine the start of civil work. Systems installation, trial runs, and safety certification will follow.

The Double-decker Experiment: Metro + Flyover

The double-decker concept gives Namma Metro Phase 3 a distinct engineering feature, by placing a vehicular flyover on the lower deck and rapid transit tracks above it.

BMRCL tender notices describe elevated structures that combine the viaduct, carriageway, and stations across certain sections of both alignments. This stacked arrangement uses one central median for two transit layers, limiting the need for separate elevated structures.

The double decker flyover Bangalore model is intended to let motorists bypass busy junctions while trains operate on an independent level.
