Ring roads are among the highest-impact urban infrastructure projects in India: they decongest city cores, speed up freight movement, catalyse peri-urban growth and shape long-term land use. Below is a curated list of India’s top 10 ring road projects (in no particular order of importance), a short summary of each, and a table that shows current completion / implementation status (sourced to recent public updates).

Short summaries & why each project matters
1. Urban Extension Road-II (UER-2) — Delhi (third ring)
UER-2 is an access-controlled expressway designed to act as Delhi’s third ring, easing traffic on the city’s inner and outer rings and improving regional connectivity across the NCR. After substantial progress in civil works, public sources in 2025 reported the corridor was close to opening. This route will take pressure off radial highways and speed up cross-city freight and passenger movements. TheAPN
2. Mumbai Ring Road network / Peripheral ring plans
Mumbai’s ring road concept is being developed as a set of ring and radial connectors — the Mumbai Ring Road masterplan aims to knit together the city, suburbs and satellite towns to improve port, airport and highway access. Implementation is phased, with multiple packages and connector projects moving at different paces. As with most megacity ring networks, the Mumbai plan is complex because of land constraints and multi-agency coordination. Homes247
3. Bengaluru Peripheral Ring Road (PRR)
Bengaluru’s PRR is a large greenfield/peripheral ring that will link major state and national highways outside the city, redistributing heavy traffic away from inner urban corridors. The PRR has advanced to stakeholder consultations and land acquisition notices in 2025, but compensation and right-of-way negotiations remain key execution challenges. Deccan Herald
4. Hyderabad Outer Ring Road (ORR)
Hyderabad’s ORR is one of India’s better-known success stories: the existing ORR is operational and has catalysed growth in the IT and logistics belts around the city. Authorities are now planning complementary regional ring corridors and upgrades to handle traffic growth. The ORR remains a model for ring road–driven urban expansion. orrhyderabad.in
5. Chennai Peripheral Ring Road (CPRR)
The Chennai Peripheral Ring Road is a greenfield, access-controlled 6-lane expressway planned to connect Ennore to Mahabalipuram and relieve congestion on radial routes. Work is proceeding in phases, with some sections in advanced stages and others at land-acquisition or tendering stages; international funding and multi-agency coordination feature in progress reports.
6. Pune Ring Road / Inner Ring concepts
Pune’s ring road planning has several strands — an Inner Ring Road by PMRDA and larger ring proposals to serve the growing Pune Metropolitan Region. Several segments and link roads are under construction with staged handovers between municipal and regional authorities. PMRDA
7. Sardar Patel Ring Road (Ahmedabad)
Ahmedabad’s Sardar Patel Ring Road is being upgraded to a 6-lane corridor, with AUDA floating key tenders and announcing overbridges and supporting works. This upgrade targets both higher intercity throughput and smoother urban access. auda.org.in
8. New Outer Ring Road — Nagpur
Nagpur’s new outer ring is an ambitious 148-km project approved at state level and positioned as a logistics and decongestion corridor to support the Samruddhi Expressway and regional connectivity. It exemplifies the trend of peri-urban ring roads planned to serve multi-state freight and passenger flows. The Times of India
9. Lucknow Outer Ring Road (NH-230 / Kisan Path)
Lucknow’s outer ring (part of NH-230 / Kisan Path network) has seen multiple packages completed and inaugurated, with remaining packages in late-stage construction as of 2025. It’s already easing traffic in key radial corridors around the Uttar Pradesh capital. Wikipedia
10. Kolkata ring road proposals
Kolkata has long-standing proposals for inner and outer ring corridors (and elevated ring link ideas across the Hooghly). While master-plans and proposal studies exist, the Kolkata ring concept remains in the planning/study phase in many sub-corridors and awaits major funding and alignment decisions. Projects Today
Common implementation challenges (and lessons)
Across India the biggest risks and delays for ring roads are similar:
- Land acquisition & compensation disputes — many projects stall here. (Bengaluru PRR and Chennai CPRR provide clear examples.) Deccan Herald
- Multi-agency coordination — ring roads touch municipal, state and national roads, utilities and environmental clearances.
- ** funding & procurement complexity** — large rings require phased financing (public budgets, HAM/PFI, multilateral loans).
- Right-of-way constraints in built-up zones — precise alignment decisions (and often expensive structures) are necessary close to cities.
Lessons from completed corridors (e.g., Hyderabad ORR) show that ring roads succeed when planning integrates land-use, nodal development and feeder infrastructure (service roads, interchanges, public transport links). orrhyderabad.in
Closing thoughts
Ring roads are more than asphalt; they reshape metropolitan economies and travel behaviour. India’s 2020s pipeline — from UER-2 in Delhi to Chennai’s greenfield CPRR, Pune and Nagpur’s new outer rings — shows policymakers are prioritising strategic orbital highways to support rapidly growing cities. For planners, the priority remains: balance speed of delivery with equitable land processes and strong integration with public transport and last-mile access so those rings drive inclusive growth rather than unchecked sprawl.
