Motorists using new elevated corridors longer than 10 km in Bengaluru will have to pay user fees, with the Karnataka government approving a toll-based development model for two projects. Bengaluru Smart Infrastructure (B-SMILE) has invited tenders for the corridors under a Build-Own-Operate-Transfer (BOOT) arrangement, with the state providing 40 per cent viability gap funding (VGF).

The two projects cover a combined 46.5 km and have an estimated cost of Rs. 58.2 bn, excluding land acquisition and utility-shifting expenses. Both corridors are classified as Category C projects, allowing the selected concessionaire to build, operate and maintain the infrastructure before recovering its investment through toll collections during the concession period.

The first corridor will extend 18.5 km from Marenahalli Main Road at Ragigudda Junction to Kanakapura Main Road, passing through BWSSB Pipeline Road and Thalaghattapura Junction. It has an estimated cost of Rs. 22.83 bn, of which the government will provide up to Rs. 9.13 bn as VGF.

The second project will cover 28 km between Yeshwanthpur at Mattikere Cross and Tin Factory Junction in KR Puram. Its route will pass through IISc, Mehkri Circle, Jayamahal, St John's Church Road and Ulsoor Lake. The estimated cost is Rs. 35.37 bn, with VGF of about Rs. 14.15 bn, equivalent to 40 per cent of the project cost.

Tender documents state that the user fee will be levied, collected and revised under the Karnataka Road User Fee (Determination of Rates and Collection) Rules, 2014, and applicable state toll notifications. Base rates will be revised annually through an increase of 3 per cent plus 40 per cent of the movement in the Wholesale Price Index. A separate proposed elevated corridor of about 7 km has not yet been assigned a toll policy.

The state Cabinet approved the wider plan in April 2026 to develop 120 km of flyovers and grade separators. Eleven elevated corridors and flyovers spanning 75.6 km have received approval at an estimated cost of Rs. 132.63 bn, with nine projects relying on direct government funding and the two longer corridors being implemented through the BOOT model.
