Namma Metro Blue Line (Airport City): Construction Update
The Namma Metro Blue Line will link Central Silk Board to Kempegowda Airport and runs straight through Devanahalli's Airport City belt. As per the latest 2026 update, the Hebbal-airport stretch is aimed for September 2027.
The full 58-km line is now expected by March 2028. This line will finally give Devanahalli real metro access. It will cut down the need for road-only travel.
Near the metro line, many prime townships like Prestige Park Lane by top builders like Prestige Group are coming up. It is a pre-launch project by Prestige Group. It sits in Devanahalli's KIADB Phase 2 belt, close to the coming Blue Line.
The 32.26-acre master plan has 9 towers with around 1,800 homes. It also has an on-site business park. Metro access nearby adds real value here over time.
Current Construction Status: Where Things Stand in 2026
The Blue Line is approximately 58.19 km with about 30 stations, divided into two stages. Phase 2A runs from Silk Board to KR Puram for a distance of 19.75 km and will have 13 stations. It was originally scheduled for December 2026 but is now expected in 2027 only.
Phase 2B is from KR Puram to the airport with 17 stations, and work is moving in sections. The 27.44 km Hebbal-airport leg aims for completion in September 2027. The 11 km KR Puram-Hebbal leg is slated for completion by December 2027.
Deputy CM D.K. Shivakumar in December 2025: Deputy CM D.K. Shivakumar gave a stern warning to the contractors not to delay the project any further. He said the companies could be blocked if the deadlines slipped again.
Route, Stations, and Depot Details Near the Airport
The airport line will go underground within the airport terminal at the KIAL Terminals station in Gangamuthanahalli. The line is also being extended to the Shettigere Depot. It is a new depot being built to accommodate trains for Phase 2B.
The project will complement the two existing depots at Doddajala and Baiyappanahalli. The entire line is divided into five construction packages. The companies involved in the construction of the line are Afcons Infrastructure, SNC Construction, and NCC Ltd.
NCC handles three packages between Benniganahalli and the airport.
How This Line Connects to Other Commuting Options
Once it opens, the Blue Line will link with the Yellow Line at Silk Board. It will also link with the Pink Line at Nagawara. This gives Devanahalli a direct link to the wider metro network in one ride. It also cuts the current reliance on NH 44 and BMTC buses for city travel.
Until then, road transport stays the main option. This includes Vayu Vajra buses and app-based cabs.
Proximity to Work Hubs Along the Corridor
The Blue Line's route runs close to big job hubs. These include KR Puram, Hebbal, and the KIADB Aerospace Park near Devanahalli. This should cut commute time for people working at Boeing, Wistron, and Foxconn. These sites all sit within the aerospace belt.
IT hubs like Manyata Tech Park also lie along the route. They too stand to benefit once trains start running.
Impact on Devanahalli's Property Market
Metro access has already pushed up prices in other parts of Bengaluru. Past trends from the Outer Ring Road show a 15 to 30% price rise. This kind of jump often happens within 18 to 36 months of a metro line opening nearby.
Devanahalli's property market is still catching up to this future value. Prices here are likely to rise faster as work nears completion through 2027.
Future Growth and Why Buyers Should Consider Investing Now
Purchasing prior to completion of a metro line generally results in greater gains than waiting. The Blue Line is still under construction. Hence, the present prices in Devanahalli do not take into account this future advantage.
Projects in the KIADB Phase 2 belt like Prestige Park Lane give buyers the opportunity to buy at today's lower prices. This is fine with construction as it progresses to its 2027-28 targets.
Conclusion
The airport line on the Blue Line isn’t merely another transit project in their eyes. It is the lost rail link that will, at last, connect Devanahalli to Bengaluru’s metro system. When sections begin opening in 2027 and 2028, this line is expected to transform daily commutes.
And it is expected to stimulate long-term property demand along the entire airport belt.
