The Satellite Town Ring Road, an NHAI expressway built under the Bharatmala Pariyojana, is quietly redrawing the map of Bengaluru's growth corridors. Implemented by the National Highways Authority of India, the STRR spans 288 km, with 243 km in Karnataka and 45 km in Tamil Nadu. This ring road links twelve satellite towns around Bangalore, including Dobbasapete, Sulibele, Hoskote, Devanahalli, Doddaballapura, Anekal, Attibele, Tattekere, Ramanagara, Kanakapura, Sarjapura, and Magadi. For homebuyers and investors tracking the Attibele-Sarjapur belt, one segment matters most: the Hoskote-Hosur stretch, which threads directly through this corridor before crossing into Tamil Nadu.
That stretch has seen its share of delays but is now in the final stretch. The Hoskote-Hosur stretch of the 280.8-km Bengaluru Satellite Town Ring Road, NH-948A, is likely to reach the Tamil Nadu border by June 2026, after a delay of nearly 16 months from its original February 2025 deadline. The National Highways Authority of India has picked up pace on the final segment, with a key rail overbridge near Lingadeeramallasandra remaining the last hurdle. Progress on the ground is already substantial: out of the total 20.9 kilometers, builders have already completed 20.25 kilometers of the road network, with only a tiny 650-meter missing link stopping this highway from opening to the public. Once this segment opens, it will take the STRR's operational length to about 102.6 km.
This isn't the corridor's first milestone. The key operational segment right now is the approximately 80-kilometre Dobbaspet–Hoskote stretch, designated as NH-648, inaugurated on March 11, 2024, with tolling operational from June 14, 2024. Together with the upcoming Hoskote-Hosur link, this gives the Attibele-Sarjapur belt a continuous high-speed spine connecting it to both North Bengaluru and the Tamil Nadu border. The STRR connects 8 state highways and 6 national highways, forming a powerful orbital network that integrates road, logistics, and industrial infrastructure around Bangalore.
What does this mean for someone living or investing near Attibele or Sarjapur today? Faster freight and commuter movement, for one. Travel time between Hoskote and Kempegowda Airport could reduce significantly once the full ring is operational, and the same logic applies to journeys between Attibele-Sarjapur and other satellite nodes. Industrial activity is already responding to this shift. The Karnataka Industrial Areas Development Board is set to develop a 647-acre industrial park in Sarjapur, spanning six villages between Attibele and Sarjapur, approved in February 2024 to address the growing demand for industrial land in Bangalore.
Property data from the corridor already reflects this momentum. Over the last five years, property rates along Sarjapur Road and Attibele have appreciated between 30% to 45%, with the announcement and execution of the STRR and PRR projects being the biggest catalysts for this boom. Looking ahead, market analysts remain bullish. Analysts predict an appreciation of 20% to 35% in emerging STRR corridors over 3–5 years, with higher returns for early plot investors and strong rental potential near industrial and logistics hubs. More specifically for this belt, experts predict a 15–20% rise in villa plot appreciation over the next three years as infrastructure nears completion.
Developers have taken note. Puravankara already has a footprint here through plotted developments in S. Medihalli, just off the Sarjapur-Attibele Road, and has recently deepened its commitment to the belt. Puravankara's premium 53.5-acre land parcel acquisition in Anekal Taluk marks the company's ambitious foray into creating a large, sustainable community with a saleable area of 6.4 million square feet and a projected Gross Development Value exceeding ₹4,800 crore. According to the company's leadership, this acquisition aligns with a "disciplined approach to growth with a long-term view" and reflects confidence in the fundamental strength of Bangalore's southern micro-markets.
For homebuyers, the takeaway is straightforward: infrastructure-led corridors tend to reward early movers. Attibele-Sarjapur, sitting at the intersection of the STRR, the Peripheral Ring Road plans, and a growing industrial base, is transitioning from an overlooked periphery to an active investment zone. As the Hoskote-Hosur stretch nears its June 2026 opening, the window to enter at pre-completion prices is narrowing.
Buyers evaluating this belt should weigh not just the road's completion timeline but also proximity to specific junctions, since actual accessibility—and land value—depends on distance to interchanges rather than the corridor label alone. Combined with rising industrial investment and steady developer activity from established names like Puravankara, the Attibele-Sarjapur stretch of the STRR is shaping up to be one of Bengaluru's more closely watched growth stories through 2026 and beyond.
