Overview

• The final Detailed Project Report by Rodic Consultants raises the project cost to ₹22,000 crore, up from earlier estimates under the BOOT model
• Design includes only eight entry and exit ramps that the report predicts will spawn 16 new surface-level gridlock spots across key junctions
• The DPR does not clarify what proportion of Bengaluru’s traffic will divert into the tunnel or how diversion will be managed
• A BBMP feasibility study by Altinok shows commuters face an average one-way trip of 18.91 km, adding over 2 km on surface roads for ramp access
• Urban planners and opposition leaders call for an independent audit, arguing car-centric solutions could undermine broader public transit investments
