Karnataka clears Hebbal-Silk Board, KR Pura-Mysuru Road tunnel road projects under BOOT model; to levy toll

“The Cabinet considered three options — the Hybrid Annuity Model (HAM), handing it over to the National Highways Authority of India (NHAI), or BOOT. It has opted for the BOOT model, and global tenders will be floated soon,” Patil said.

Under the BOOT model, the concession period has been set at 30 years, during which the selected private players will recover their investment through toll collection. The details of toll modalities will be finalised later, he added.

Government sources said tenders for the high-cost Hebbal-Silk Board infrastructure project — estimated at Rs 17,780 crore — are likely to be issued within the next seven to 10 days.

The detailed project report (DPR) of Bengaluru’s twin-tube tunnel road project between Hebbal and Silk Board Junction has estimated a toll of Rs 330 for a distance of 16.6 km.

The report also highlights that the tolls for subsequent years are calculated on the basis of a 5 per cent annual increase in Wholesale Price Index with a 40 per cent restriction. The base year for the toll revenue is FY 2030-31. Importantly, the toll estimates have been proposed only for cars, with no mention of other vehicles.

According to the report, a toll rate of Rs 320 is estimated for Hebbal-Sarjapur/HSR Layout (16.3 km), Rs 250 for Hebbal-Hosur Main Road (12.79 km), Rs 180 for Hebbal-Seshadri Road (9.05 km), Rs 320 from Outer Ring Road, K R Puram-Silk Board Junction, Rs 245 for Mekhri Circle to Silk Board Junction (12.54 km), and Rs 195 for Race Course-Silk Board Junction (9.8 km).

Further, the study has also estimated toll rates of Rs 255 from Jayanagar to Hebbal (13 km), Rs 245 from Jayanagar to Outer Ring Road and KR Puram (12.36 km), and Rs 130 from C V Raman Road to Hebbal (6.60 km).
