Hebbal Junction Works: Flyover, Tunnel and Metro Explained for Home Buyers
Hebbal junction is the meeting point of Bellary Road, the Outer Ring Road and the road to Kempegowda International Airport. Several projects are under way at this one junction: new flyover ramps, a road tunnel towards Mekhri Circle, the airport metro line and a suburban rail station. This guide explains each project, its stage in October 2026 and what a home buyer in North Bangalore should weigh.
Why Hebbal Junction Matters
Traffic from four directions shares the Hebbal flyover. Airport traffic comes down Bellary Road, office traffic arrives from Manyata Tech Park and KR Puram on the Outer Ring Road, and city traffic comes up from Mekhri Circle. Tumkur Road traffic joins from the west through Yeshwanthpur and BEL Circle.
The junction decides the daily commute for a wide belt of housing. Hebbal, Kempapura, Sahakara Nagar, Jakkur, Thanisandra and Yelahanka all send traffic through it to reach the city centre. A buyer in any of these areas is, in effect, buying into the future of this junction.
The Projects at the Junction
Four agencies are building at Hebbal at the same time. The table below shows each project and its stage in October 2026:
| Project | Agency | Stage |
|---|---|---|
| Flyover ramp from the KR Puram side to Mekhri Circle | Bangalore Development Authority | Open since 18 August 2025 |
| Road tunnel from Hebbal junction towards Mekhri Circle | Bangalore Development Authority | Foundation stone laid on 28 June 2026 |
| Elevated corridor at Mekhri Circle | Bangalore Development Authority | Approved, tendered |
| Blue Line metro with a station at Hebbal | Bangalore Metro Rail Corporation | Under construction |
| Suburban rail station at Hebbal | K-RIDE | Under construction |
A single plan for the whole junction has also been under preparation, so that the road, tunnel and metro designs fit together. Earlier flyover designs at Hebbal had to be changed to make room for the metro viaduct. Planning the pieces together is meant to avoid that kind of rework.
The New Flyover Ramp
The first piece of relief is already in use. A 700 m ramp built by the Bangalore Development Authority at a cost of about Rs. 80 crore opened on 18 August 2025. It gives traffic from Nagavara and KR Puram a direct path towards Mekhri Circle, and the traffic police reported a clear fall in congestion at the flyover in the first week.
The Hebbal Tunnel
The Karnataka Cabinet approved a Rs. 2,215 crore project on 4 December 2025 for a short tunnel at Hebbal junction and an elevated corridor at Mekhri Circle. The foundation stone for the tunnel was laid on 28 June 2026. The tunnel is a little over 2 km long, with three lanes in each direction, and is built by the cut-and-cover method.
The route starts at Hebbal junction on Bellary Road and passes under the railway line and the Outer Ring Road. It then runs beneath the veterinary college campus and surfaces near the staff quarters of the University of Agricultural Sciences. The tunnel will be toll-free, and this first stretch is budgeted at Rs. 1,139 crore from the funds of the Bangalore Development Authority.
The stated construction period is 18 months from the foundation stone. Large road projects in Bangalore often take longer than first announced, so the date is best treated as a target. The tunnel is also described as the first part of a longer planned underground corridor from Hebbal to Silk Board.
Metro and Suburban Rail
The Blue Line of Namma Metro runs from Central Silk Board to the airport through KR Puram, Nagavara, Hebbal and Yelahanka. The section through Hebbal is under construction, with stations planned at Kempapura, Hebbal and Kodigehalli. The Orange Line approved under Phase 3 is planned to end at Kempapura, and a further line from Hebbal to Sarjapur is proposed.
The suburban rail corridor from Baiyappanahalli to Chikkabanavara, under construction by K-RIDE, also has a station at Hebbal. A multimodal hub with a metro depot and parking has been proposed on about 45 acres of industrial board land near the junction. The transfer of that land has been a point of dispute, and the hub has no confirmed timeline.
What It Means for Home Buyers
Better access through Hebbal helps the whole of North Bangalore, though each area gains in a different way. The points below show how the main housing belts are placed:
- Hebbal and Kempapura are closest to the tunnel mouth and the metro station, and closest to the construction
- Bellary Road localities such as Sahakara Nagar and Jakkur gain a quicker run to the city centre once the tunnel opens
- Thanisandra and Nagavara use the Outer Ring Road side of the junction and already benefit from the 2025 ramp
- Yelahanka and the airport road beyond it depend on Hebbal for every trip to the city
The benefit arrives in stages over several years. A flat bought in 2026 near the junction will see barricades, diversions and dust before it sees a faster commute. Buyers who plan to live in the home soon should judge the area as it is today.
Risks to Weigh
Three risks deserve a plain look before paying a premium for an address near Hebbal. The first is the construction period itself, when lane closures can make peak-hour traffic slower than it was before. The second is delay, as tunnel, flyover and metro dates in the city have moved many times.
The third risk is land. Road widening, tunnel ramps and metro works need land along Bellary Road and around the junction, and acquisition notices can affect individual properties. A resale buyer on a main road near the junction should confirm that the plot is clear of any road-widening or acquisition line.
Checks Before Buying Near Hebbal Junction
A few checks turn the news about the junction into a decision about one specific home:
- Drive from the project to the workplace at peak hours, through the junction as it is today
- Measure the distance from the project gate to the nearest active work site and to the planned metro station
- Ask the developer how the project entrance connects to the service road during the construction years
- Verify the RERA number, completion date and sanctioned plan of the project on the Karnataka RERA portal
- Compare the asking price with similar homes a few kilometres from the junction, to see what the location premium is
- Plan to hold the home for five years or more if the purchase depends on the tunnel and the metro
The price paid today should match the connectivity that exists today. Milestones such as tunnel excavation, metro trial runs and station openings are the right evidence for any higher price. We track these projects and share the current status of each on request.
