Construction of a 700-meter six-lane underpass is now underway at the Sadahalli junction.
The project aims to make the Hebbal to Kempegowda International Airport corridor completely signal-free.
Heavy construction is scheduled to begin in September 2026, with an expected completion date of February 2027.
The Sadahalli toll plaza remains Karnataka's highest revenue generator, collecting 308 crore rupees in 2023-24.
