The Karnataka state administration has launched a 2.2-kilometer twin-tunnel project at Bengaluru's Hebbal Junction. Fully funded by the Bangalore Development Authority for ₹11.3 billion, the toll-free sub-surface route aims to ease severe northern corridor gridlock within two years.
The Karnataka provincial government has initiated construction on a major underground transport project designed to ease northern Bengaluru's severe traffic bottlenecks. According to official disclosures, the groundwork has commenced for a 2.2-kilometer, three-lane transitory twin tunnel connecting Hebbal Junction to the Karnataka Veterinary, Animal and Fisheries University campus. The Bangalore Development Authority is the primary statutory urban planning and infrastructure development agency responsible for public works in the metropolitan area. The capital-intensive project is valued at over ₹11.3 billion and will be executed via the cut-and-cover engineering method, with a targeted completion timeline of 24 months.
This development matters because it targets a critical arterial chokepoint linking downtown Bengaluru to its international airport corridor. By redirecting localized surface traffic underground, the toll-free infrastructure aims to bypass the heavily congested junctions underneath the Hebbal Flyover, directly relieving adjacent commercial and residential zones.
On a policy level, the project highlights the complexities of municipal fiscal management. State finance officials initially flagged the tunnel as an expensive short-term fix, recommending a surface road expansion at a fraction of the cost. However, the executing agency bypassed this because of prohibitive land acquisition overheads and structural expansion barriers, setting a precedent for sub-surface engineering over traditional road-widening schemes.
For civil engineering firms, heavy construction equipment suppliers, and regional real estate developers, this ₹11.3 billion infrastructure injection indicates sustained public expenditure on metropolitan connectivity. This sub-surface bypass, coupled with an upcoming elevated corridor to Mehkri Circle, will optimize logistics flow, stabilize neighborhood land values, and reduce long-term transport operational overheads for northern metropolitan businesses.
