The Peripheral Ring Road on Sarjapur Road does not exist yet. As of September 2026, it is a planned 73 km, 8-lane road that BDA now calls the Bengaluru Business Corridor. Only the first 19.8 km package, in north Bengaluru, has reached the bidding stage. The Sarjapur Road section is a later phase. This guide covers the route, the status and the real trade-offs for buyers.
What the Peripheral Ring Road is
Bengaluru already has the Outer Ring Road, or ORR, which runs through Bellandur and Marathahalli. The PRR is a second, wider ring further out. Its job is to let lorries and through traffic skip the city.
BDA, the Bangalore Development Authority, owns the project. In 2024 it renamed the road the Bengaluru Business Corridor. Most buyers and brokers still call it the PRR, so we use both names here.
Per 2026 reports on the BDA plan, the road will be:
- About 73 km long, from Tumakuru Road in the north-west to Hosur Road in the south-east.
- An 8-lane, access-controlled road with service lanes on both sides.
- About 65 m wide, down from the 100 m first planned, per some late-2025 reports.
- Linked to 11 major junctions, including Sarjapur Road and Hosur Road.
The total cost is about ₹27,000 crore, per reports. Most of that money goes to buying land, not to building the road.
The planned route
The PRR runs as a half-ring around the north and east of Bengaluru. It starts near Madavara on Tumakuru Road. It then crosses Hesaraghatta Road, Doddaballapur Road and Ballari Road, the airport road in north Bengaluru.
From there it swings east and south towards the Whitefield side. It crosses Hennur Road, Old Madras Road and Hoskote Road. It then cuts across Sarjapur Road and ends on Hosur Road at Konappana Agrahara, near Electronic City.
The table below shows the three phases as BDA has described them in 2026 reports.
| Phase | Stretch | Status as of September 2026 |
|---|---|---|
| Phase 1 (Package 1) | Tumakuru Road to Ballari Road, about 19.8 km | Tender floated 31 March 2026; two bids opened 8 May 2026 |
| Phase 2 | Ballari Road to Old Madras Road, via Hennur Road | Not yet at award stage, per reports |
| Phase 3 | Old Madras Road to Hosur Road, via Sarjapur Road | Not yet at award stage, per reports |
So the part that matters most for Sarjapur Road buyers sits in the last phase. That is worth keeping in mind whenever you hear a PRR claim.
Status in 2026: land, tenders and delays
The PRR has a long record of false starts. BDA cancelled an earlier tender in July 2024. Land has been the main hurdle, since farmers along the route wanted better payment.
The state then offered a richer set of choices to landowners. Per reports, owners can pick one of these:
- Cash at about 2 times market value in urban areas, or about 3 times in rural areas.
- Transferable Development Rights, known as TDR.
- Extra floor area (FAR) on the land they keep.
- A share of developed plots in BDA layouts.
BDA began issuing land awards in early 2026. For Package 1, reports say BDA had about 83% of the land it needs by March 2026. That is progress, but the Sarjapur Road stretch still has land left to buy.
Package 1 went out to global tender on 31 March 2026 at about ₹3,348 crore. Two firms bid by 8 May 2026. The tender gives the builder 36 months from the work order. So even the first stretch will take until about 2029 at best.
How the PRR compares with the ORR
The ORR is the ring most Sarjapur Road residents use today. It links Silk Board, Bellandur, Marathahalli and KR Puram. Over the years, offices and homes grew all along it, and it now carries heavy local traffic.
The PRR plan tries to avoid that fate. It is access-controlled, so side roads cannot join it at will. Traffic can enter and leave only at planned junctions. In theory, that keeps the main lanes fast for longer than the ORR.
The PRR also sits much further out than the ORR. For a Gattahalli resident, the ORR at Bellandur or Silk Board is the nearer ring today. The PRR would add a second, outer choice, mainly for trips to the north and east of Bengaluru.
Where the PRR sits near Gattahalli
Adarsh Welkin Park is in Gattahalli, off Sarjapur Road, on Rayasandra Road beside Gattahalli Lake. The developer’s location map marks the proposed PRR close to the site. It runs south towards Hosur Road, on the side away from the city.
The same map shows other planned roads near the site. These include a proposed 100 ft road and two CDP roads, 24 m and 30 m wide. CDP means the Comprehensive Development Plan, the city’s master plan for land use. You can view the map in the location section of the homepage.
A word of caution: a line on a developer’s map is not a road. BDA can shift an alignment, and CDP roads can take years to open. Always check the final plan with BDA before you rely on any of them.
The PRR would pair with the planned Sarjapur Road metro, which is also years away. We cover that line and its status in our Sarjapur Road metro guide.
What the PRR could change for residents
If the PRR opens, Sarjapur Road residents would gain a fast link that avoids the ORR. Here is what could change, compared with today:
| Trip | Today | If the PRR opens |
|---|---|---|
| To Hosur Road and Electronic City | Rayasandra Road to Hosa Road junction | A second route along the PRR to Konappana Agrahara |
| To Whitefield and Old Madras Road | Via Sarjapur Road and the ORR, or via Varthur | A direct run north along the PRR |
| To the airport | Via the ORR and Hebbal | Along the PRR to Ballari Road, skipping the core city |
| Lorry traffic on Sarjapur Road | Mixed with local traffic | Some through traffic could shift to the PRR |
These gains need the whole ring, not just one phase. A PRR that stops at Ballari Road does little for a trip from Sarjapur Road. The value comes only when Phase 3 links through to Hosur Road.
Risks and trade-offs for buyers
A planned road can help a home, but it also brings risks. Here is a balanced view.
- Delay risk. The PRR has slipped more than once, and the Sarjapur Road stretch is last in line. Plan your commute on roads that work today.
- Noise and dust. An 8-lane road brings heavy vehicles. Homes right beside it may face more noise than homes a few hundred metres away.
- Building work. Once work starts, local roads near the route may see diversions for 3 years or more.
- Land deals. If you buy land or a plot near the route, check that it is not inside the road’s land plan. That risk is lower for a RERA-registered flat in an approved project.
- Price talk. Some sellers say a road “will raise prices”. No one can promise that. Treat such claims with care and ask for evidence.
For a flat buyer, the PRR is a long-term bonus, not a reason to buy. The home should already suit your work, school and budget without it. Adarsh Welkin Park has a reported possession date of December 2028 onwards. That is likely before the Sarjapur Road stretch of the PRR opens.
How to check PRR claims yourself
Buyers in Bengaluru often hear two stories about the PRR. One says it will open soon; the other says it will never come. The truth, as of September 2026, sits in between. Package 1 has real bids, but the Sarjapur Road stretch has no builder yet.
Many listings along Sarjapur Road mention the PRR. Here are four quick checks before you trust that claim:
- Ask which phase covers that stretch. For Sarjapur Road, the answer is the third phase.
- Ask whether BDA has awarded a work order for that phase. As of September 2026, public reports cover only the Package 1 tender.
- Measure the road distance from the home to the planned route, using BDA’s map.
- Look for a date on any news you read. PRR stories from 2022 or 2024 can be out of date.
You can also check the project’s RERA details and master plan on the homepage. Both help you judge the home on facts that exist today. More Sarjapur Road guides sit on the blog.

Frequently asked questions
No. As of September 2026 the PRR is a planned road. Work has not started on the Sarjapur Road section; the first package BDA put out to tender is the 19.8 km stretch from Tumakuru Road to Ballari Road.
It is the new name BDA gave the Peripheral Ring Road in 2024. The plan is a 73 km, 8-lane access-controlled road from Tumakuru Road to Hosur Road, crossing Sarjapur Road on the way.
Per 2026 reports on the BDA plan, the southern end meets Hosur Road at Konappana Agrahara near Electronic City. Check the final alignment with BDA before you rely on it.
There is no fixed date for the full road. Reports in 2026 cite a broad target around 2029, and each package needs 30 to 36 months once work starts. Delays have been common on this project.
The developer's location map marks the proposed PRR close to the site, along with a proposed 100 ft road. Treat both as proposals until BDA builds them.
