A 73 km Expressway Two Decades in the Making Finally Moves to Construction

Some infrastructure projects define a city's next chapter. The Bengaluru Business Corridor is one of them. It has taken nearly two decades to move from proposal to clearance to tender, and it is now moving to concrete.

• Environmental clearance was granted by the Ministry of Environment, Forest and Climate Change on April 27, 2026, the single most consequential pending approval for the project.

• Global tenders worth Rs 3,348 crore were floated by the BDA in March 2026 for the first 20 km stretch from Madavara to Ballari Road, with bids submitted on May 8, 2026 by two infrastructure firms.

• The corridor is a 73.5 km, eight-lane access-controlled expressway with 3+3 service lanes inside a 100-metre right of way, signal-free and high-speed, with 11 cloverleaf interchanges.

• The alignment connects Tumakuru Road in the northwest to Hosur Road in the south, passing through Hesaraghatta, Ballari Road, Hennur, Old Madras Road, Whitefield, Channasandra and Sarjapur Road.

• It is designed to link with NICE Road at both ends to form a full orbital network, with provisions for a future metro line, cycling tracks and pedestrian walkways.

Officials project a 40 percent reduction in city traffic once it is operational, the most significant road decongestion infrastructure Bengaluru has seen in a generation. The micro-markets set to benefit directly include Hebbal, Yelahanka, Hennur, Whitefield, Channasandra, Sarjapur Road and the entire peripheral arc of the city.

For buyers on Sarjapur Road, Whitefield, Hennur and the North Bengaluru corridors, the BBC is the most important road development of the decade. It reduces travel time, but it also connects residential catchments that currently feel peripheral, both to each other and to the highway network, in a way that reshapes their long-term value.
