What Bengaluru is proposing
Bengaluru Smart Infrastructure Ltd has invited bids for a 28-km elevated corridor between Yeshwanthpur and KR Puram, a project described as the city's first toll flyover. The estimated cost is ₹3,536 crore, and the tender uses a Build-Own-Operate-Transfer model.
Under BOOT, a private concessionaire finances and builds the project, operates it for an agreed period and then transfers it. Toll revenue is intended to help recover investment and an allowed return.
The tender caps the concession at 11,863 days, or about 32.5 years. That is a maximum, not a promise that every bidder will collect tolls for the full period.
The proposed route
The corridor begins near Mathikere Cross in Yeshwanthpur and runs through or near IISc, Mekhri Circle, Jayamahal, St John's Church Road and Ulsoor Lake. It then heads toward KR Puram through the Old Madras Road side.
Plans include a split flyover at MEI Junction, 10 up ramps and 10 down ramps. The four-lane elevated structure is planned at about 19.61 metres wide with design speeds of 60-80 km/h.
The route addresses major junctions including RT Nagar Main Road, Ulsoor Lake, Indiranagar and Varthur Road. Final ramp placement will determine which neighbourhoods gain useful access and where surface congestion may increase.
How the toll period will be decided
Instead of fixing one concession period, BSMILE has made the number of operating days a bidding parameter. A bidder states how long it needs to recover investment and returns. A proposal exceeding the 11,863-day cap is rejected.
In theory, competition should reward a bidder that can deliver the project with a shorter toll period. In practice, the comparison must also consider toll escalation, traffic assumptions, construction quality and how risk is shared with the government.
The public needs a clear answer on what happens if traffic is below or above projections. A contract can include extensions, compensation or revenue-sharing mechanisms, but the tender says the total period cannot exceed the cap.
Why planners want an east-west corridor
Existing Metro travel between Yeshwanthpur and Indiranagar generally passes through Majestic, creating a less direct journey. The elevated road is intended to bypass the central business district for through traffic.
Supporters expect shorter cross-city driving times and less pressure at surface junctions. The 30-month construction deadline, if achieved after award and clearances, would be relatively fast for a project of this length.
However, new road capacity can attract additional car trips. If ramp queues spill onto local streets, congestion may shift instead of disappearing. Integration with Metro, buses and parking policy determines the long-term effect.
Questions the final contract should answer
- What will the opening toll be and how will it rise?
- Are buses, emergency vehicles or certain users exempt?
- Who pays for delays, utility shifting and land problems?
- How will construction affect trees, lakes and neighbourhood access?
- What service levels trigger penalties?
- Will revenue be audited and published?
- What happens at the end of the concession?
Transparency matters because a 32-year cap can extend across several generations of transport technology and urban growth.
What happens next
The tender process must evaluate technical and financial bids before an award. Detailed design, clearances, traffic plans and site preparation follow. The public should not treat the invitation as proof that construction will begin immediately.
