Quick answer

Namma Metro currently runs the Purple and Green lines plus the Yellow Line to Bommasandra, roughly 96 km in service. Three more packages are under construction: Phase 2A along the eastern Outer Ring Road, Phase 2B to Kempegowda International Airport, and Phase 3 in the west. BMRCL is the implementing authority, and the airport link is the single change most likely to reset North Bengaluru prices.

Introduction

Ask any Bengaluru buyer what decides a locality's next five years and the answer is usually the same: how far is the nearest metro station, and when does it actually open. Namma Metro has grown from a 42 km Phase 1 network into a system that now touches Whitefield in the east, Bommasandra in the south and Madavara in the north-west. What is still being built matters even more, because the corridors under construction connect the parts of the city that generate the most daily commuting pain — the Outer Ring Road tech belt, the airport road, and the western suburbs.

This guide sets out what is running, what is being built, who is building it, and how each corridor tends to move property prices and rents around its stations. Where a completion date is not officially committed, we say so instead of guessing.

What is Bangalore Metro Expansion?

Namma Metro is operated by the Bangalore Metro Rail Corporation Limited (BMRCL), a joint venture of the Government of India and the Government of Karnataka. The network is built in phases, and each phase opens in stretches rather than all at once — which is why a station can be "opening soon" for several years.

What is operational today

  • Purple Line (east–west): Whitefield (Kadugodi) to Challaghatta, via Baiyappanahalli, Indiranagar, MG Road, Majestic and Mysore Road.
  • Green Line (north–south): Madavara to Silk Institute, via Peenya, Yeshwanthpur, Majestic, Jayanagar and Banashankari.
  • Yellow Line (south-east): RV Road to Bommasandra along Hosur Road, serving BTM Layout, Central Silk Board, HSR Layout and Electronic City.

What is under construction

  • Phase 2A — Blue Line, Central Silk Board to KR Puram: about 19.75 km elevated along the eastern Outer Ring Road with 13 stations.
  • Phase 2B — Blue Line, KR Puram to the airport: about 38.4 km with around 17 stations via Hebbal, Jakkur and Yelahanka.
  • Phase 3 — Orange Line: two corridors totalling roughly 44.65 km, along the western Outer Ring Road (JP Nagar to Kempapura) and from Hosahalli to Kadabagere on Magadi Road.

Approved in principle

Phase 3A (Sarjapur to Hebbal) is a roughly 37 km corridor at the detailed planning and funding stage; construction dates are not committed.

How to read metro news as a buyer

An announcement, a tender award, a trial run and a commercial opening are four very different events. Prices usually move twice — when alignment and stations are confirmed, and again when trains actually run. Buying between those two events is where most of the upside sits, provided the property works on its own merits today.

Timelines for large infrastructure projects change. Entries labelled expected or reported are not guaranteed completion dates.

Real estate impact

Property prices

Homes within comfortable walking or short-auto distance of an operational station have tended to command a visible premium over similar stock 3–4 km away — Whitefield after the Purple Line extension and the Electronic City belt after the Yellow Line are the clearest examples. Expect the same pattern on Phase 2A and 2B.

Rental market

Rents respond faster than sale prices because tenants can move immediately for a better commute. Station-adjacent 2 and 3 BHK stock typically sees shorter vacancy and firmer renewals.

Infrastructure may support prices, rentals and liquidity, but outcomes depend on delivery timelines, supply and broader market conditions. PropertyVest does not guarantee appreciation or returns.

Investment outlook

Treat the metro as a tie-breaker, not a reason to overpay. Prefer a completed or near-complete project within 1–2 km of a confirmed station, with clear title and a developer who has delivered nearby.

Potential benefits

  • Connects the ORR, Electronic City and airport-road employment belts
  • Removes road traffic from the daily commute equation
  • Station catchments hold rental demand better in slow markets
  • Encourages walkable development around nodes
  • Improves resale liquidity within 1–2 km of a station

Risks & considerations

  • Opening dates slip routinely
  • Prices near unbuilt corridors can run ahead of reality
  • Last-mile access from station to home is often poor
  • Construction years bring dust, diversions and rental softness
  • Alignment changes can move a station away from a project

PropertyVest publishes risks alongside opportunity. Infrastructure timelines and property outcomes are not guaranteed.

Conclusion

Once Phase 2A and 2B run, Bengaluru will have rail access from the airport to the eastern tech belt without touching the Outer Ring Road — likely shifting both office and premium residential demand northwards.

Frequently asked questions

How long is the Bangalore Metro network today?

Roughly 96 km is in commercial service across the Purple, Green and Yellow lines.

When will the metro reach the airport?

Through Phase 2B from KR Puram. Construction is advanced, but only BMRCL announcements should be trusted for the opening date.

Which line serves the Outer Ring Road tech belt?

Phase 2A of the Blue Line, from Central Silk Board to KR Puram, with stations at Bellandur, Kadubeesanahalli and Marathahalli.

Is Sarjapur getting a metro?

Phase 3A proposes a Sarjapur–Hebbal corridor. It is approved in principle with no committed construction timeline.

Does a metro station increase property value?

Usually, in two steps — when the alignment is confirmed and when trains run. The premium is largest within walking distance.

Who builds Namma Metro?

BMRCL, a joint venture of the Government of India and the Government of Karnataka.
