Ring roads and bypasses around India's major cities have become critical infrastructure for managing urban congestion. According to MoRTH data from 2026, urban areas account for over 40% of India's road traffic despite having only 3% of the total road length. The NHAI and state governments have prioritised ring road construction to divert through-traffic away from city centres. Cities like Delhi, Mumbai, Bengaluru, Chennai and Hyderabad have all seen significant ring road expansion in recent years, with several projects completing in 2026.

Delhi Ring Roads
Delhi has a three-tier ring road system. The Inner Ring Road (22 km) covers central areas including Connaught Place. The Outer Ring Road (47 km) connects major residential areas. The Dwarka Expressway (29 km) and the Eastern and Western Peripheral Expressways (135 km each) form the third tier, diverting through-traffic away from Delhi entirely.
The Eastern Peripheral Expressway (EPE) connects Kundli to Palwal via Ghaziabad and Noida, while the Western Peripheral Expressway (WPE) connects Kundli to Palwal via Sonipat and Manesar. Together, they form a 270 km ring around Delhi. According to NHAI 2026 data, these peripheral expressways divert approximately 50,000 vehicles daily from Delhi's internal roads.
Mumbai Ring Road & Bypasses
Mumbai's ring road infrastructure includes the Western Express Highway (25 km from Bandra to Dahisar) and the Eastern Express Highway (23 km from Sion to Thane). The Mumbai Trans Harbour Link (Atal Setu), opened in January 2024, has created a new 21.8 km sea bridge connecting Mumbai to Navi Mumbai.
The under-construction Coastal Road (Phase 1 operational, Phase 2 ongoing) provides a 29 km high-speed corridor along Mumbai's western coast from Marine Drive to Kandivali. The Delhi-Mumbai Expressway also serves as a bypass for through-traffic heading north from Mumbai.
Bengaluru Outer Ring Road
Bengaluru's Outer Ring Road (ORR) is a 62 km expressway circling the city. The ORR connects major tech corridors including Whitefield, Electronic City, Hebbal and Manyata Tech Park. According to Bangalore Metropolitan Region Development Authority (BMRDA) data, the ORR handles over 200,000 vehicles per day. The PRR (Peripheral Ring Road), a 116 km project at an estimated cost of ₹17,000 crore, is under construction and will form an outer tier bypassing the current ORR.
Chennai Outer Ring Road
Chennai's Outer Ring Road (ORR) is a 62 km expressway under construction by TNRDC. Phase I (29 km from Vandalur to Nemilichery) is operational, while Phase II (33 km from Nemilichery to Minjur) is progressing. The ORR connects NH-45, NH-4, NH-205 and NH-5, providing seamless bypass connectivity. When complete, it will reduce cross-city travel time by up to 60%.
Hyderabad ORR
Hyderabad's Outer Ring Road (ORR) is a 158 km eight-lane expressway completed in 2012. It is one of India's longest urban ring roads. The ORR connects Hyderabad to the Rajiv Gandhi International Airport via the PV Narasimha Rao Expressway. Traffic on the ORR has grown from 80,000 vehicles per day in 2015 to approximately 250,000 in 2026, according to Hyderabad Metropolitan Development Authority (HMDA) data.
Ring Road Comparison Table
| City | Ring Road | Length | Lanes | Daily Traffic | Status |
|---|---|---|---|---|---|
| Delhi | Peripheral Expy | 270 km (E+W) | 6 | 50,000+ | Operational |
| Mumbai | Coastal Road | 29 km | 8 | 100,000+ | Phase 2 ongoing |
| Bengaluru | ORR | 62 km | 6-8 | 200,000+ | Operational |
| Chennai | ORR | 62 km | 6 | 80,000+ | Phase 1 open |
| Hyderabad | ORR | 158 km | 8 | 250,000+ | Operational |
Conclusion
Ring roads and bypasses have become essential for managing urban traffic in India's growing cities. The three-tier approach — inner ring road, outer ring road, and peripheral expressway — adopted by Delhi provides a model for other cities. With projects like Bengaluru's PRR and Chennai's ORR Phase II progressing, 2026 is seeing continued investment in urban bypass infrastructure.

Hyderabad's Outer Ring Road at 158 km is India's longest urban ring road. It is an eight-lane expressway completed in 2012.
What are Delhi's Peripheral Expressways?
Delhi's Eastern and Western Peripheral Expressways form a 270 km ring around Delhi, diverting approximately 50,000 through-traffic vehicles daily from the city's internal roads.
Is the Mumbai Coastal Road fully operational?
Phase 1 of the Mumbai Coastal Road (Marine Drive to Worli) is operational. Phase 2 (extending to Kandivali) is under construction and expected to complete in 2027.
How much traffic does Bengaluru's ORR handle daily?
Bengaluru's Outer Ring Road handles over 200,000 vehicles per day, connecting major tech corridors including Whitefield and Electronic City.
What is the Peripheral Ring Road (PRR) in Bengaluru?
The PRR is a 116 km project at an estimated cost of ₹17,000 crore that will form an outer tier beyond the current ORR, further reducing city traffic.
Are ring roads in India tolled?
Most major ring roads use FASTag-based tolling. Hyderabad's ORR charges ₹0.85-2.00 per km. Delhi's Peripheral Expressways are also tolled.
