Satellite Town Ring Road: What Is Built, What Is Delayed, What Is Tendered
Plots around Bangalore's edge are frequently priced on one idea, that a ring road will soon circle the city. The Satellite Town Ring Road (STRR) is real, yet only one arc of it is in use in October 2026. This guide covers what the road is, how each part is doing and what a careful buyer should confirm.
The project in plain terms
Under Bharatmala, the NHAI is building a controlled-access national highway of about 280.8 km. The new stretches carry NH 948A, and the north and east follow NH 648, the former NH 207, after realignment. Lanes number four to six, and vehicles are meant to travel at up to 100 km per hour.
The aim is to let goods vehicles and through traffic skip the city. By the plan, twelve towns are linked. Dobbaspet and Sulibele anchor the north, Hoskote and Sarjapura the east, and Ramanagara and Magadi the west, with Doddaballapura, Devanahalli, Attibele, Anekal, Tattekere and Kanakapura in between. A short portion near Hosur is inside Tamil Nadu.
A different ring, the Bengaluru Business Corridor (formerly the Peripheral Ring Road), belongs to the state and runs far nearer the city. The two should not be confused.
Open, almost open, not started
The open portion comes first. Eighty kilometres of finished highway join Dobbaspet and Hoskote, opened on 11 March 2024, with toll on both packages. Four lanes serve the first 42 km, which end at the Doddaballapura bypass and have been tolled since June 2024. The remaining 38 km to Hoskote have six lanes and have been tolled since November 2023.
Next is the 20.9 km Hoskote link. Its first target was February 2025, and further dates have gone by. The road is mostly laid, and the open item is roughly 650 metres where a rail overbridge needs two bowstring girders of 54 metres each over the railway line from Bengaluru to Chennai.
The drawing for launching those girders got South Western Railway's approval in June 2026. What remains is a speed inspection by RDSO, the railways' standards body. The opening date stays uncertain until the launch, so ask the NHAI for the latest.
The rest is further back:
- About 36 km in Tamil Nadu, up to Belagondapalli near Hosur: a contractor has been appointed
- About 65 km from the Hosur side to Ramanagara: bids invited, environmental clearance awaited because the route skirts Bannerghatta National Park, where an 8.1 km elevated road is planned
- About 79 km from Ramanagara through Magadi to the Dobbaspet side: bids invited
Five packages, around 144 km in all, went out for bids in September 2024, spread over the Bannerghatta and western parts. The estimated cost is Rs. 4,750 crore, and no opening date is fixed.
Who gains, and how soon
The ring helps cargo and cross-region trips more than the morning commute, so each belt feels it differently. Hoskote is best placed, since the Bengaluru-Chennai Expressway and Old Madras Road both meet the ring there, which favours warehouses and factories. In Devanahalli and Doddaballapura, the open arc already gives signal-free access to the airport belt from two major roads.
Sarjapura, Attibele and Anekal will see little until the Tamil Nadu section and the Hoskote link are both open. The three towns of Kanakapura, Ramanagara and Magadi rely on tenders that have not yet become works on the ground. The daily drive of someone employed in Whitefield will barely change.
The gains come from logistics and industrial jobs, and homes tend to follow such jobs gradually. A buyer near Hoskote should keep that timeline in view.
A buyer's checklist
Sales material near the ring usually puts the highway first. Use these steps to separate fact from promise:
- Pick out the part nearest to the land and read its status without optimism.
- Measure the real drive to an interchange, since access is limited to those points.
- Ask for the layout approval, the conversion order and the RERA registration.
- Examine the title papers and the khata type, as a road cannot repair a weak title.
- Count the toll in the cost of regular trips.
- Compare the price with approved layouts located farther from the alignment.
- Pay for roads that are usable today and regard unbuilt parts as extra gain.
A buyer in the north is paying for something already in use. The east has little work left, though dates have slipped before. Elsewhere the ring exists as a proposal only, and a price that treats it as done leaves the buyer waiting unpaid.
