Blue Line Metro on the ORR: Status and Buyer Checks (October 2026)
The Blue Line is the Namma Metro corridor planned to run from Central Silk Board along the Outer Ring Road to KR Pura, and on through Hebbal to Kempegowda International Airport. It is under construction, and the opening of its first stretch has moved into 2027. This guide explains the route, how far the work has come by October 2026 and what home buyers along the ORR and in North Bangalore should weigh before paying for metro access.
The Route in Two Phases
The Blue Line is one continuous elevated corridor of 58.19 km with 30 stations, built in two phases. Its estimated cost is Rs. 14,788 crore, with loans from the Asian Development Bank and the Japan International Cooperation Agency. The two phases are these:
- Phase 2A: Central Silk Board to KR Pura along the Outer Ring Road, 19.75 km
- Phase 2B: KR Pura to the airport through Hebbal and Yelahanka, 38.44 km
Phase 2A serves the IT corridor of the ORR, while Phase 2B links East Bangalore with the northern suburbs and the airport. Together they form the first metro line to serve the airport.
Stations on the ORR stretch
Phase 2A has 13 planned stations between Silk Board and KR Pura. In order from the south, they are:
- Central Silk Board, HSR Layout, Agara Lake and Iblur
- Bellandur, Kadubeesanahalli and Kodibisanahalli
- Marathahalli, ISRO and Doddanekkundi
- DRDO Sports Complex, Mahadevapura and KR Pura
Silk Board is planned as an interchange with the Yellow Line, which has run to Electronic City and Bommasandra since August 2025. KR Pura connects with the Purple Line, which already serves Whitefield and the city centre.
Stations on the airport stretch
Phase 2B runs north from KR Pura through Kasturinagar, Horamavu, HRBR Layout and Kalyan Nagar to Nagawara and Hebbal. It then follows Bellary Road past Kodigehalli, Jakkur Cross and Yelahanka to the airport, where the terminal station is underground. Nagawara is planned as an interchange with the Pink Line.
Progress as of October 2026
In August 2026, the BMRCL said that starting commercial operations on the Silk Board to KR Pura stretch within 2026 was no longer feasible, and moved the target into 2027. Trial runs had earlier been expected around October 2026. Construction across the whole line was reported to be about 72% complete in August 2026.
The delays come from a handful of unfinished pieces of work. The main ones reported are these:
- The connection from the line to the depot at Byappanahalli, which trains need for operation and maintenance
- Utility shifting at Iblur, including a gas pipeline and water lines, along with land acquisition
- Viaduct, drainage and clearance work at Central Silk Board
- A travelator link to the Yellow Line station, which was still at the tender stage
The airport stretch is targeted for phased opening after the ORR stretch, with completion of the whole line aimed at the end of 2027. These dates have changed several times, so it is safer to treat any single date as a target rather than a commitment.
What It Means for Home Buyers
The ORR between Silk Board and KR Pura holds some of the city's largest office campuses, and road traffic on it is slow at peak hours. A working metro would give residents of Bellandur, Marathahalli and the Mahadevapura belt a fixed travel time to work. It would also make homes further out, in Whitefield, Hennur and the airport belt, easier to reach from those offices.
The benefit, though, arrives only when the trains run, and the date has already moved. A purchase that only makes sense with the metro open should be planned on a later date than the most hopeful one. A home that works on today's road commute, with the metro as a bonus, carries far less timing risk.
ORR and East Bangalore
Homes within a short walk of a planned station gain the most once the line opens. A distance of up to about 1 km on foot is a practical catchment; a project 2 or 3 km away will still need a car, bus or auto to reach the station. The Greater Bengaluru Authority has also scheduled white-topping work on the ORR from October 2026 to January 2027, which will affect road travel along the corridor through the winter.
North Bangalore and the airport belt
For buyers in Hebbal, Yelahanka, Jakkur and the airport belt, the airport stretch adds a rail link to both the city and the ORR offices. It opens after the ORR stretch, and many new projects in this belt are themselves due between 2028 and 2031. Matching a project's own possession date with the metro timeline gives a clearer picture than the brochure map alone.
Checks Before Paying for Metro Access
Developers often price nearness to a metro line into the rate. These checks help judge whether that premium is fair:
- Find the nearest planned station on the official alignment, not on a marketing map.
- Walk the route from the project gate to the station site and time it.
- Compare the price with similar projects further from the line.
- Test the commute by road at peak hour, since that is the daily journey until the trains run.
- Read the project's own RERA completion date alongside the metro target.
Buyers looking at the eastern end of the ORR can start with the KR Pura locality page. The same checks apply at every station along the line, from Silk Board to the airport.
