Access-controlled expressway

Peripheral Ring RoadTumakuru Road to Hosur Road

Peripheral Ring Road (Bengaluru Business Corridor)

The Peripheral Ring Road, rebranded the Bengaluru Business Corridor and now described as 117 km, was first notified in 2005. Its record since includes land acquisition disputes, Supreme Court and High Court litigation, and a quashed environmental clearance. Package 1 (Madavara to Ballari Road) got a contractor in June 2026, against a latest government deadline of 2029. Public figures conflict on the total cost (₹27,000 crore or ₹17,000 crore), on the number and length of packages, and on tree loss. No public record reviewed establishes the original completion date or the outcome of the High Court petitions that officials expected to be decided by mid-2026.

Wards within 50 m of the alignment traced from OpenCity's October 2023 PRR alignment map, as mapped in OpenStreetMap (checked 17 September 2026). Kaun derived this list; the agency does not publish one. About 59 km of that alignment lies outside GBA wards.

Open accountability gap

Landowners say BDA's August 2026 notifications, which state that possession of PRR-1 land was taken in February 2011, breach High Court orders and contradict the state government's 2021 affidavit to the Supreme Court that only 3 acres 21 guntas of 1,810 acres had been taken.

Estimated cost

₹17,000–27,000 Cr

The cabinet pegged the project at ₹27,000 crore in September 2024. After the October 2025 cabinet meeting, Deputy CM D.K. Shivakumar told reporters it would fall to ₹17,000 crore; June 2026 reporting still cites about ₹27,000 crore. The 2016 approval was ₹11,950 crore.

Land possessed by 2021

3 of 1,810 acres

The state government's affidavit of 9 November 2021 to the Supreme Court, quoted in the Karnataka High Court's December 2024 judgment: 3 acres 21 guntas of 1,810 acres 18.5 guntas.

Package 1 land

78%

523 of 665 acres as of May 2026, reported from BBCL's chairman. Package 2 had 123 of about 433 acres; Package 3 had 26 of about 710.

  2. Landowners say BDA's August 2026 possession notifications violate High Court orders and contradict its Supreme Court affidavit

    PRR-1 landowners said BDA's 18 August 2026 Gazette notifications, which state that possession of their land was taken in February 2011, violate High Court interim and status-quo orders. They cited the 2021 affidavit to the Supreme Court recording that compensation had been paid in only three cases and possession taken of 3 acres 21 guntas of 1,810 acres 18.5 guntas. The PRR farmers' association said it would petition the government to withdraw or suspend the notifications.

  3. Work order for Package 1 to be issued

    BBCL's chairman said the contractor had submitted its performance bank guarantee and the engineering section had been directed to sign the agreement and issue the work order within two days. A final notification was also issued for land to integrate the project with the NICE corridor at Madavara village. The work order's issue date and construction period were not found in the public sources reviewed.

  4. Letter of Acceptance issued to SNC for Package 1 at about ₹3,500 crore

    SNC received the LoA for Package 1, a 21-km Madavara-Ballari Road stretch with three cloverleaf interchanges, a grade separator, two rail overbridges, about 7.5 km of elevated corridor and a 12-lane carriageway, having quoted 4.9% above estimate (about ₹3,500 crore including maintenance). The LoA itself is not publicly posted; naming rests on attributed reporting of BDA/BBCL's announcement. The Hindu's report put the overall project estimate at about ₹27,000 crore, of which nearly ₹21,000 crore for land acquisition — conflicting with the ₹17,000 crore figure given after the October 2025 cabinet.

  7. MoEFCC grants environmental clearance

    The Ministry of Environment, Forest and Climate Change granted environmental clearance to the PRR/BBC on 27 April 2026, per Deccan Herald and other outlets. TOI separately reported that the PRR 'obtained the environmental clearance only in 2023'; whether the 2026 clearance covers a revised scope or a distinct phase is not resolved in the public sources reviewed. The original clearance was quashed by the NGT in 2019 and the Supreme Court ordered a fresh EIA in 2020.

  11. High Court refuses to quash Part II acquisition; orders compensation and road completion

    Justice E.S. Indiresh, disposing of the Byrappa batch (WP 61154/2014 with five others) over PRR Part II, refused to quash the acquisition of about 31 acres where no award had been passed since the 2005-06 preliminary and 2011 final notifications. He directed BDA to pass awards, pay compensation within six months, take possession, and complete the remaining 1.8 km of the 10.3 km road (8.5 km was already built). The judgment quotes the state government's affidavit of 9 November 2021 to the Supreme Court: of 1,810 acres 18.5 guntas notified, possession had been taken of only 3 acres 21 guntas.

  13. Supreme Court: 2013 land Act does not apply to BDA acquisitions

    In BDA v State of Karnataka, the Supreme Court held that the Land Acquisition Act, 1894, stands incorporated into the BDA Act, so the 2013 Act (including its lapse and higher-compensation provisions) does not govern PRR acquisitions, overruling the 2014 single-judge judgment.

    In BDA v Sudhakar Hegde (Civil Appeal 2566/2019), the Supreme Court, invoking Article 142, noted BDA's 'abject failure' to state correct tree figures (BDA claimed 519; the Deputy Conservator of Forests counted 16,785) and undisclosed forest land at Jarakabande Kaval, and directed BDA to hire a sector-specific accredited EIA consultant and obtain environmental certification afresh, with no damage to petroleum pipelines on the alignment.

  18. High Court: acquisition not lapsed, but compensation under 2013 Act

    A Single Judge deciding WP 4550/2008 (Sudhakar Hegde) and connected petitions held the PRR acquisition had not lapsed under Section 24 of the 2013 land acquisition Act, but that compensation must be determined under the 2013 Act since no award had been passed. BDA said this upset the project's budget calculations and moved the Supreme Court.
