Peripheral Ring Road Phase 2: South Bangalore's Next Big Connectivity Push

A two-decade-old infrastructure plan for South Bangalore is finally moving off paper and onto the ground. The 40-km Peripheral Ring Road, which will run parallel to NICE Road between Mysuru Road and Hosur Road, is back on the agenda. The Bangalore Development Authority has started serving formal notices to landowners as it works to push the project forward, more than 20 years after it was first conceived.

The road's alignment is designed to solve a long-standing gap in South Bangalore's network. The second phase of the Peripheral Ring Road project aims to connect Mysuru and Hosur roads via Bannerghatta and Kanakapura roads. Effectively, it gives commuters and residents a second east-west spine south of the city, running alongside the existing NICE corridor rather than replacing it. The Bangalore Development Authority has begun issuing notices to farmers in several villages as it moves to revive the two-decade-old project, with documented notices reaching villages such as Bylakonenahalli, KJ Lakkenahalli, Gangondahalli, Lakshmipura and Dombarahalli.

The project's history explains why this revival is significant news. This stretch along with the first phase of PRR were notified for land acquisition around the same time in 2006-07 but both the proposals remained on the drawing board as the government did not have enough funds to pay for land losers. At one point, the second phase was nearly scrapped entirely — its original alignment ran too close to Bannerghatta National Park and cut through Ashraya-scheme housing in Gottigere, prompting talk of formally closing the project and denotifying the land. That closure never fully materialised, and the plan has now resurfaced with fresh momentum.

On cost and scale, the numbers give a sense of what's involved. The BDA has estimated the second phase to cost Rs 1,589 crore, after notifying 2,700 acres for the PRR's Phase II (51 km) back in 2006. Some industry trackers describe the current alignment as a 40 km corridor connecting Kanakapura Road (linking to PRR Phase 1) through to Mysore Road, running through villages including Hullahalli, Hulimangala, Bingipura and Begur.

This phase doesn't exist in isolation — it's one piece of a larger ring strategy around Bengaluru. Phase 1 of the PRR, a separate 73-km stretch through the north and east of the city, was approved by Karnataka's state government in February 2022 for development on the public-private partnership design, build, finance, operate and transfer model. This 100m wide greenfield expressway along with the operational NICE Peripheral Ring Road will form a 116 km bypass around Bengaluru once both phases and the NICE corridor are fully integrated.

For homebuyers, the practical upside lies in reduced dependence on a single congested corridor. Links the southern corridors through Kanakapura Road and connects to Mysore Road, opening up the relatively underdeveloped southwestern periphery. As the BDA's land notices move from paperwork to physical acquisition, localities along Hosur Road, Bannerghatta Road and Kanakapura Road are likely to see renewed developer and investor interest, given the direct road access this corridor promises once construction begins in earnest.

That said, buyers should treat this as an early-stage infrastructure signal rather than a completed project. Land acquisition notices are a necessary first step, but PRR Phase 2 has missed multiple earlier timelines since 2006. The safer approach for homebuyers is to track official BDA and BBC (Bengaluru Business Corridor) announcements for acquisition completion and construction start dates before factoring the road into near-term price expectations, while still recognising the long-term connectivity upside for the Hosur-Bannerghatta-Kanakapura belt.
