Namma Metro Blue Line: ORR Progress and What Buyers Should Weigh
Namma Metro's Blue Line is planned to carry commuters along the ORR corridor and onward to the airport. Construction continues, yet passengers will not board the first stretch before 2027. This article sets out what the position was in October 2026, how the stations are arranged and which questions buyers on the ORR and in the north should raise before paying extra for a metro address.
Progress and Delay
The BMRCL said in August 2026 that a passenger opening within the year had become unrealistic for the southern section. The target now falls in 2027. Trial runs were first expected in about October 2026. The BMRCL put overall construction near 72% in August.
Four jobs account for most of the slip, according to reports.
- A track link to the Byappanahalli depot, needed to run and maintain trains
- Iblur needs gas and water pipelines moved, and some land is still to be acquired
- Central Silk Board still needs viaduct, drainage and clearance jobs
- The travelator to the Yellow Line platform, with tenders yet to be awarded
The northern section is meant to open in phases after the ORR trains start, and the entire line is due by the end of 2027. Dates have been revised more than once, so each is best seen as a goal only.
Route, Cost and Interchanges
The Blue Line is an elevated corridor, 58.19 km in length, with 30 stops and an estimated cost of Rs. 14,788 crore. Part of the money comes as loans from JICA of Japan and the Asian Development Bank. It will be the first Namma Metro line to reach the airport. The work is divided into two packages.
- Phase 2A is 19.75 km long, following the ORR from the Silk Board junction to the KR Pura terminus
- Phase 2B is 38.44 km, carrying it on beyond KR Pura via Hebbal and Yelahanka to the terminal
Three interchanges are planned. Passengers will change to the Yellow Line at Silk Board; that line has gone as far as Electronic City and Bommasandra since August 2025. The Purple Line towards Whitefield and the centre meets the Blue Line at KR Pura, and the Pink Line meets it at Nagawara.
The thirteen ORR stations
Going north, Central Silk Board is the first stop and HSR Layout the next. Agara Lake comes after that, then Iblur and Bellandur. Kadubeesanahalli and Kodibisanahalli follow, leading to Marathahalli.
The last stretch are ISRO, Doddanekkundi, the DRDO Sports Complex and Mahadevapura, ending at KR Pura. Each is on the elevated section.
The airport section
After KR Pura the corridor heads for Kasturinagar and Horamavu, then HRBR Layout, followed by Kalyan Nagar, before Nagawara and Hebbal appear. On Bellary Road the stops are Kodigehalli and Jakkur Cross, with Yelahanka after them. The terminal station is the only underground one.
What a Delay Means for Buyers
Big office campuses crowd the ORR, and traffic at peak hours barely moves. When trains start, residents of Bellandur and Marathahalli, and across the Mahadevapura belt, gain a fixed journey time. Whitefield and Hennur, along with the airport zone, also become simpler to reach from those workplaces.
Everything hinges on trains running, and the opening has moved once already. Buying purely for the metro calls for a later year than the best-case one in the plan. Choosing a home that suits today's road journey, with the metro as an added benefit, removes most of the timing risk.
Along the ORR, walking distance matters. About 1 km is a realistic catchment, while a project that lies 2 or 3 km off will still need a vehicle. Road trips will also be slower this winter, as the GBA has scheduled white-topping works on the ORR for October 2026 to January 2027.
In Hebbal, Yelahanka, Jakkur and neighbourhoods by the airport, the northern section would add a rail route to the centre as well as the ORR offices. It arrives later, and plenty of projects in that belt are scheduled for completion in 2028 to 2031. Putting a project's possession date beside the metro schedule is more telling than any brochure map.
Questions to Ask About a Metro Premium
Sales teams often fold nearness to a station into the rate. Five checks show whether that is worth paying.
- Confirm where the station falls on the official alignment, never a sales map
- Time the walk from the gate of the project to the planned station
- Set the price beside similar projects farther from the line
- Try the peak-hour road journey, which stays the daily route for now
- Match the RERA completion date to the metro target
For the eastern end, the locality page for KR Pura is a sensible first stop. The same questions apply wherever a station is planned.
