Drive out towards Hoskote, Doddaballapur or Devanahalli and you will see plot layouts with large boards: 'Near PRR', 'STRR facing', 'Ring road plots'. Some have been advertising the same promise for over a decade. Others sit next to a highway that really is open and carrying traffic.
Two different projects often get mixed up here: the Peripheral Ring Road (PRR), now called the Bengaluru Business Corridor, and the Satellite Town Ring Road (STRR). One is still mostly on paper; the other is partly built. Knowing which is which can save you from paying a premium for a road that may be years away.
The Peripheral Ring Road (Bengaluru Business Corridor)
What it is
The PRR is a planned 73 to 74 km road around the city's outer edge, run by the Bangalore Development Authority (BDA). It is designed to link Tumakuru Road in the north-west to Hosur Road in the south-east, crossing Hesaraghatta Road, Doddaballapur Road, Ballari Road, Hennur Road, Old Madras Road and Sarjapur Road on the way. Together with the existing NICE Road on the south-western side, it would complete a ring of roughly 116 km around Bengaluru.
The plan is for an eight-lane main road with service lanes on either side, mainly so that trucks and through traffic can bypass the city.
Where it stands as of November 2026
The PRR was first proposed around two decades ago. Tenders in 2022 and 2024 drew no workable bids, mainly because land costs had risen so much. Rebranded as the Bengaluru Business Corridor, the project is now being built in phases:
- Phase 1, Tumakuru Road to Ballari Road (about 20 km): tenders were invited in March 2026 at an estimated ₹3,348 crore, with a 36-month build period once work starts. Officials said about 83% of the land for this phase had been acquired.
- Phase 2, Ballari Road to Old Madras Road via Hennur Road: to follow as land becomes available.
- Phase 3, Old Madras Road to Hosur Road: the last stage.
Total cost estimates range from about ₹20,000 crore to ₹27,000 crore. Landowners can choose cash (reported at two times market value in urban areas and three times in rural areas), development rights (TDR) or a share of developed plots. Compensation disputes have stalled the project more than once.
We could not confirm that a construction contract for Phase 1 had been signed by November 2026. Before relying on any timeline, check BDA's latest announcements.
The Satellite Town Ring Road (STRR)
What it is
The STRR (NH-948A) is a much larger, outer ring, roughly 280 to 288 km, built by the National Highways Authority of India (NHAI). It links the satellite towns around Bengaluru: Dobbaspet, Doddaballapur, Devanahalli, Hoskote, Sarjapur, Attibele, Anekal, Kanakapura, Ramanagara and Magadi, with a section passing through Tamil Nadu near Hosur.
Where it stands as of November 2026
- Open: the 80 km stretch from Dobbaspet to Hoskote, via Doddaballapur and near Devanahalli, opened in March 2024 and is tolled.
- Nearly done: the Tamil Nadu section to Belagondapalli was reported over 91% complete in August 2026, and the 21 km stretch from Hoskote to the Karnataka-Tamil Nadu border was targeted for November 2026. Together, about 144 km of the eastern half was expected to be usable by around November 2026.
- Later: the western and southern sections, through Anekal, Kanakapura, Ramanagara and Magadi, are at earlier stages. The stretch near Bannerghatta National Park needs environmental clearances.
How these roads actually affect property
Ring roads help property in specific ways, and not in others:
- They help logistics and industry first. Warehouses, factories and truck routes benefit most. That brings jobs, which brings housing demand over time.
- They help towns at junctions. Places where the ring road meets a major highway, such as Hoskote, Doddaballapur and Devanahalli, gain the most.
- They do not make city commutes much shorter. Living near the STRR does not put you closer to Koramangala or the ORR offices. It mainly helps you go around the city.
- Homes right next to them are not always better. Heavy trucks bring noise and dust. A home 1 to 2 km from an interchange is often more pleasant than one facing the highway.
Plots versus flats near ring roads
Most of the 'ring road' marketing is for plots. If you are considering one, the risks are higher than for a flat in a city project:
- Example: a 1,200 sq ft plot priced at ₹30 lakh because it is 'near PRR' versus a similar plot 3 km further away at ₹22 lakh. You pay ₹8 lakh more for proximity to a road whose later phases may take years to build. If the road arrives late, that ₹8 lakh earns nothing in the meantime, and plots generate no rent.
- Approvals matter more than distance. A plot in a BDA, BMRDA or local planning authority approved layout with a clear title near Doddaballapur is worth more than a cheaper unapproved plot 'facing' the alignment.
- Land acquisition risk: check that the plot is not inside the road's own alignment or required land. If it is, it may be acquired.
What to check before buying near the PRR or STRR
- Get the official alignment from BDA (for PRR) or NHAI (for STRR) and confirm the exact distance to the nearest planned interchange.
- Confirm the land is not marked for acquisition. Ask a lawyer to check notifications for the survey number.
- Check layout approval and conversion. For plots, look for DC conversion of agricultural land, an approved layout plan and a clear title for at least 30 years.
- Verify RERA registration for plotted developments and apartment projects that need it, on the Karnataka RERA website.
- Look at what exists today: water, power, schools, hospitals and bus or rail connections. Buy for what is there, and treat the road as upside.
- Plan your hold period. Ring road benefits usually take years to show. If you may need the money back within three years, think twice.
Rules on land conversion and approvals vary by area, so have a property lawyer review documents for your specific plot before you pay a token amount.
Frequently asked questions
Are the PRR and the STRR the same road?
No. The PRR (Bengaluru Business Corridor) is a 73 to 74 km BDA road closer to the city. The STRR is a 280 km plus NHAI highway further out, linking satellite towns.
Is any part of the STRR open?
Yes. The 80 km Dobbaspet to Hoskote stretch has been open since March 2024. More of the eastern section was expected to open around November 2026.
When will the Peripheral Ring Road be ready?
Phase 1, Tumakuru Road to Ballari Road, was tendered in March 2026 with a 36-month build period once work begins. The later phases depend on land acquisition and have no firm date as of November 2026.
Is it a good idea to buy a plot near the STRR?
It can be for patient buyers who choose approved layouts near interchanges in towns with existing demand, like Hoskote or Doddaballapur. Avoid paying extra purely because of the road.
If you are considering a plot or home near either ring road, Skyros Estates can help you check approvals, title and alignment details before you commit.
