Bengaluru's Blue Line Metro: The Airport Corridor Takes Shape

There is a particular kind of anticipation that settles over a city when its infrastructure promises are, at last, inching toward reality. Bengaluru is living through such a moment now, as the long-awaited Blue Line metro corridor prepares for its first trial runs. For homebuyers who have watched the Outer Ring Road's traffic snarls and dreamed of a quieter commute to Kempegowda International Airport, this is welcome, tangible news.

According to recent updates from Karnataka's development authorities, BMRCL will begin trial runs on the Blue Line starting October 2026, with the 19.75-km Phase 2A between Central Silk Board and KR Puram leading the way. Before the required CMRS examination, trains, signalling, power supply, and other safety systems will be subjected to trials, a process that typically precedes several months of testing before passenger operations commence. Under regulatory approval, passenger operations will begin in 2027, followed by phases of the airport extension.

The scale of the project is worth pausing on. The 58.19-km Blue Line is being developed through two phases, Namma Metro Phase 2A and 2B, which will link Central Silk Board to Kempegowda International Airport, housing a total of 29 stations across the corridor. Phase 2A alone threads through some of the city's busiest tech and residential nodes, including Central Silk Board, HSR Layout, Agara, Iblur, Bellandur, Kadubeesanahalli, Marathahalli, ISRO, Doddanekkundi, DRDO Sports Complex, and KR Puram. For anyone commuting daily along the ORR IT belt, these names carry the weight of years spent in traffic.

The northward extension, Phase 2B, is where the airport promise truly comes alive. Officials have indicated that the Hebbal-Airport section is targeted for completion by June 2027, while the Hebbal-KR Pura segment is expected to be ready by the end of that year. Once complete, this stretch will run north through Kasturinagara, Nagawara, Hebbal and Yelahanka along Airport Road, finally reaching KIAL Terminals at Kempegowda International Airport, offering the city its first direct rail link to the airport without a transfer.

There have been real, physical milestones too, not just timelines on paper. Namma Metro received its first driverless train for the airport corridor in early June, with static tests beginning at the Baiyappanahalli depot even as track work on parts of the route remains unfinished. It is a reminder that mega-infrastructure of this kind advances unevenly, in fits of visible progress punctuated by the slower, invisible labour of civil works, cabling, and safety certification.

Godrej's own footprint in this story is worth noting. BMRCL's records show that Godrej & Boyce Mfg. Co. Ltd. was awarded a contract for the architectural finishing of seven elevated stations along Phase 2A, including Kadubeesanahalli, Marathahalli, ISRO, Doddanekundi, DRDO Sports Complex, Saraswathi Nagar, and KR Puram. This places the Godrej name quite literally at the heart of the corridor's construction, alongside its growing residential presence in the city's northern growth belt.

That residential presence is considerable. Godrej MSR City, a 62-acre township in Shettigere, sits close to the Doddajala Metro Station on the Blue Line's airport extension, positioning residents within easy reach of the future terminal link. Further along Doddaballapur Road, Godrej Aravya Estate offers plotted development in a corridor that is expected to benefit from improved connectivity as the metro network matures northward. For families weighing where to put down roots in Bengaluru's next decade, the Blue Line's progress, however incremental, is a signal worth watching closely.

Meanwhile, Bengaluru's metro story does not end with the Blue Line. The Pink Line's elevated stretch between Kalena Agrahara and Tavarekere has been undergoing final inspections in mid-August 2026, with CMRS clearance being the last step before passenger services begin, a reminder that the city's rail ambitions are advancing on multiple fronts at once, gradually stitching together a more connected, less congested Bengaluru.
