Namma Metro Blue Line Route and Stations

The Blue Line is an elevated metro corridor that connects the Outer Ring Road business belt to the airport in the north of the city. BMRCL designed the alignment to run mostly above ground, with a single underground station planned at the airport terminal. The route threads through some of the busiest employment hubs in Bangalore, including HSR Layout, Bellandur, Kadubeesanahalli and Marathahalli, before moving through the residential belts of Kalyan Nagar, Hebbal and Yelahanka on its way north. This alignment gives office commuters on the ORR a rail option for the first time, and it gives air travellers a direct train connection to the terminal without depending on road traffic.

The 58.19 km corridor is split into two building phases, and each phase covers a distinct stretch of the city with its own construction timeline.

Phase 2A: Central Silk Board to KR Puram

Phase 2A covers close to 18 km along the Outer Ring Road and links Central Silk Board to Krishnarajapura, commonly known as KR Puram. This stretch passes through HSR Layout, Agara, Ibbalur, Bellandur, Kadubeesanahalli, Marathahalli,and Mahadevapura, which together form one of the densest office corridors in the city. Civil works on this stretch are largely complete, though depot connectivity and finishing works at a couple of stations remain in progress as of August 2026.

Phase 2B: KR Puram to Kempegowda International Airport

Phase 2B extends the line by roughly 38 to 40 km from KR Puram to the airport, taking commuters through Kasturi Nagar, Kalyan Nagar, Nagawara, Hebbal, Jakkur & Yelahanka before reaching Doddajala and the terminal precinct. This section carries the bulk of the remaining construction work, and civil progress stood at around half complete as of mid-2026, which pushed the expected opening into late 2027.

The table below lists every planned station in order, grouped by the phase it belongs to.

The Blue Line ties into three existing metro lines and one planned line, which lets commuters switch corridors without leaving the metro network.

• Central Silk Board links the Blue Line to the Yellow Line, giving ORR commuters a route down towards Electronic City.
• KR Puram links the Blue Line to the Purple Line and to the Krishnarajapuram railway station, which opens up fast access to Whitefield and the city centre.
• Nagawara links the Blue Line to the Pink Line, connecting the northern neighbourhoods to central areas.
• Hebbal is planned as a future interchange with the Orange Line once that corridor is built.

BMRCL has pushed back the original completion targets more than once, and the timeline as it stands in August 2026 looks like this.

Trial runs on Phase 2A were expected to begin around October 2026, but BMRCL has flagged that a few stations along this stretch still need finishing work before commercial services can start. Phase 2B remains the longer wait, with civil works at roughly half complete through the middle of 2026.

The Outer Ring Road carries some of the heaviest office traffic in the city, and road journeys between Silk Board and Marathahalli often stretch well beyond an hour during peak period. Once Phase 2A opens, commuters working in this belt will have a rail alternative that removes them from that congestion entirely. The airport link in Phase 2B solves a separate problem, since travellers currently depend on cabs or buses for a journey that can take well over an hour from the city centre. A direct metro connection cuts that dependency and gives the north Bangalore corridor a level of connectivity it has not had before.

The Blue Line follows a pattern seen across Indian cities, where a confirmed metro or ring road corridor pushes up demand and prices in the neighbourhoods it touches, often years before the first train run. Buyers who enter early on such corridors, whether in Bangalore or in a growing city like Mysuru, tend to benefit the most once the infrastructure goes live. , Prestige Group's residential project in Huyilalu, Mysuru, sits on a similar growth curve, with the Bhogadi corridor and the upcoming Mysuru Peripheral Ring Road expected to shape pricing there over the next few years. The lesson from ORR and the Blue Line applies just as well outside Bangalore, infrastructure timelines move slower than expected, but early buyers on a confirmed corridor usually come out ahead.

The Namma Metro Blue Line will eventually link the Outer Ring Road business district to the airport through a single 58.19 km corridor with 30 stations. Phase 2A, covering Silk Board to KR Puram, sits closer to completion and should open first, while Phase 2B to the airport carries a longer runways into late 2027. Commuters and residents along this corridor should keep an eye on BMRCL's official updates, since opening dates on large metro projects tend to shift as final testing and safety clearances progress.
