What is the B-SMILE elevated corridor plan?

B-SMILE is the state-owned infrastructure company that now plans Bengaluru's big road projects, including the Hebbal to Silk Board tunnel road (see Bangalore Tunnel Road Project Status 2026: Route, Toll, Date). In December 2025 Deccan Herald reported that B-SMILE had finalised detailed project reports (DPRs) for 13 elevated corridors with a combined length of 126.44 km and a cost of ₹18,204 crore. In October 2026 the paper described the same package as 13 projects of about 126 km at about ₹18,000 crore.

The plan has two types of project. Short and medium flyovers are tendered on an EPC basis, where the government pays a contractor to build. The long corridors are tendered on a BOOT (toll) basis, where a private developer builds and collects tolls, with the government paying 40% of the cost as viability gap funding. Construction periods in the tender documents are 18 months for the EPC flyovers and 30 months for the Ragigudda BOOT corridor, and the EPC tenders include 10 years of maintenance.

Bengaluru elevated corridors list: routes and tender values

The list below is built from the B-SMILE tender documents (dated 20 May 2026 for the EPC works and August 2026 for the toll corridors), the December 2025 DPR proof-check tender, and OpenCity's June 2026 explainer, which lists DPR costs. Where the tender amount and DPR cost differ, both are shown. Tender amounts exclude GST, utility shifting and land acquisition.

  • Yeshwanthpur (Methikere Cross) to Old Madras Road (Tin Factory, KR Puram) via IISc, Mekhri Circle, Jayamahal, St John's Church Road and Ulsoor Lake: 28 km, six-lane, BOOT toll, ₹3,536.89 crore in the tender including 40% VGF. OpenCity lists a DPR cost of ₹4,621.45 crore.
  • Marenahalli Main Road (Ragigudda junction) to Kanakapura Main Road (Thalaghattapura) via BWSSB Pipeline Road: 18.5 km, BOOT toll, ₹2,283.19 crore in the tender, 30-month build. Deccan Herald quotes about ₹2,956 crore.
  • Old Madras Road to the Electronic City flyover via Swami Vivekananda Road metro station, Indiranagar, Old Airport Road and Hosur Road: EPC tender of ₹852 crore. Lengths differ by source: the tender and Deccan Herald say 5.2 km to Madiwala, the December 2025 DPR list said 10.81 km, and a June 2026 report said 11.62 km at ₹1,300 crore.
  • Sirsi Circle to Nayandahalli on Mysuru Road: 5.20 km, EPC, ₹538.28 crore.
  • Sholay Circle to St John's Hospital Road on Hosur Road via Anepalya and Adugodi junctions: EPC, ₹519 crore.
  • Doddaballapura Road (police station junction) to Kogilu Circle via Old Yelahanka Town: EPC, ₹103 crore.
  • Konanakunte Cross flyover on Kanakapura Road: EPC, ₹77.18 crore.
  • Adyar Ananda Bhavan, Raghuvanahalli Cross flyover on Kanakapura Road: EPC, ₹42.10 crore.
  • Minerva Circle to Hudson Circle: DPR cost ₹725 crore (OpenCity).
  • Pipeline Road (Laggere): DPR cost ₹489 crore (OpenCity).
  • Tumkur Road to MEI Junction: DPR cost ₹52 crore (OpenCity).
  • Nagavara Junction to Bagalur Main Road via RK Hegde Nagar: 17.94 km, at DPR proof-check stage (December 2025).
  • Mother Teresa Circle (Ulsoor Lake junction) to Bagalur village on the new airport road via Assaye Road: 27.19 km, at DPR proof-check stage (December 2025).

Which elevated corridors will be tolled?

The two corridors tendered on BOOT (toll) terms are Yeshwanthpur to KR Puram and Ragigudda to Kanakapura Road. The tender documents call the toll period 'dynamic duration', and no per-km rate has been published. In September 2025 Deccan Herald reported that the state planned tolls on future elevated corridors and double-decker roads because B-SMILE has no revenue of its own. The same report noted the ₹19 per km toll proposed for the tunnel road.

For a buyer, a toll changes the commute maths. A corridor you pay to use every day saves time but adds a monthly cost, and many daily users may stay on the free road below. Do not assume a tolled corridor will lift prices along its whole length.

Why are residents protesting, and were the tenders cancelled?

On Sunday 11 October 2026, about 500 people formed human chains on Indiranagar 80 Feet Road, 100 Feet Road and at Rose Garden in Jayanagar, according to Oneindia. The 'Dear DK, Flyover Yaake?' campaign asked the government to cancel all 13 tenders and put the money into public transport.

In Indiranagar, residents object because the route runs along tree-lined roads that were recently white-topped. Deccan Herald reported that some residents have gone to the High Court. On Kanakapura Road, the objections are that the Green Line metro already links the two ends and that the pipeline alignment is lined with trees. Asianet Newsable added that five Cauvery water pipelines run along that route. The protest group claims more than 10,000 trees could be cut; that is the group's figure, not an official one.

Asianet Newsable reported on 12 October that the Urban Development Department had cancelled the bidding for nine flyover and elevated corridor projects worth about ₹3,060 crore, after questions about eligibility rules. It did not name the nine projects, and the cancellation does not by itself mean the plan is dropped. We could not find an official order, so treat this as reported, not confirmed.

What does this mean for flats near these corridors?

A corridor that exists only as a DPR or a cancelled tender should carry almost no price premium. Even after an award, Bengaluru's record is slow: the 2.38 km Ejipura flyover started in 2017 and is still not open (see Ejipura Flyover Opening Date 2026: Status, Ramps, Homes).

The bigger near-term effect is construction. A flat next to a pillar line on 100 Feet Road, Hosur Road or Pipeline Road would face two to three years of dust, diversions and noise if work starts. Ground-floor and lower-floor units facing the road are hit hardest, and resale during construction is usually harder.

How to track the status of a corridor yourself

Tenders and awards are published on the Karnataka public procurement portal (kppp.karnataka.gov.in), which the B-SMILE tender documents name as the bidding channel. A project moves from DPR, to tender, to award, to work order. Only the last two stages make a timeline meaningful.

  • DPR prepared or proof-checked: idea stage, no timeline.
  • Tender floated: interest from contractors, still reversible, as the reported cancellations show.
  • Contract awarded and agreement signed: real, but land and utility shifting can still add years.
  • Barricades and pillar work on site: start counting the 18 to 30 month build periods from here, and add a margin.
