Barapullah Phase-III Flyover: Design Flaws Trigger City-wide Gridlock
By Drooid · · How we work
Core Event
The Barapullah Phase-III elevated corridor, inaugurated on September 29 2026 by Union Home Minister Amit Shah, opened to the public on September 30 2026. Within a day, traffic on the 8-km stretch from Safdarjung Hospital to Sarai Kale Khan stretched into hour-long queues, spilling onto the Ring Road, Outer Ring Road, Mathura Road, the DND flyway and Bhairon Marg. A Delhi Traffic Police drone survey identified two critical design problems: (1) multiple three-lane approaches merging into a single three-lane corridor, and an abrupt, near-90-degree lane termination at the Sundial Park loop.
Background & Context
Barapullah Phase-III was conceived in the mid-2000s to create a signal-free link between Mayur Vihar and AIIMS, easing pressure on NH-24, the DND flyway and the Ring Road. Approved in 2014, construction began in 2015 and the project, costing roughly INR1,635 crore, opened twelve years later. Traffic-volume forecasts were based on vehicle registrations from 2008–2017; by 2026 the registered fleet had nearly doubled, altering demand patterns.
Data & Statistics
- Lane configuration: Two three-lane roads (Mayur Vihar spur and Sundial Park loop) feed into a three-lane main carriageway; the existing Barapullah stretch downstream has only two lanes.
- Traffic volume: Police estimate 5–6 lakh vehicles entered the new corridor on the first day.
- Observed delays: Tailbacks of 3–4 km, with journeys taking 40–55 minutes to the first merge point and some commuters spending over two hours on the flyover.
Why It Matters / Impact
The congestion undermined the corridor’s promised 15-minute travel time, forcing drivers onto alternative routes and creating secondary bottlenecks on the Ring Road and DND flyway. Emergency services were also affected; at least four ambulances were trapped in the jam on the second day. The episode illustrates how adding road capacity without redesigning downstream junctions can exacerbate city-wide traffic, a phenomenon known as “capacity drop” and “shock-wave” braking.
Official Statements & Responses
- Senior traffic police officers said personnel deployment at critical merging points would be intensified, and the remaining carriageway (AIIMS -> Mayur Vihar) was opened on October 1 2026 to relieve pressure.
- PWD officials acknowledged that the project’s planning studies are over 20 years old and that retrofitting measures—such as lane-balancing and possible ramp-metering signals—are under discussion.
Criticism & Opposition
- Alabhya Dhamija, an Advocate-on-Record, blamed Google Maps for directing a sudden influx of vehicles to the new route, resulting in a “20–25 minute” loss of time and a barricaded entry.
- Sarika Panda Bhatt, co-founder of the Raahgiri Foundation, warned that “lane balancing” and gradual lane reduction are needed to prevent drivers from encountering an abrupt narrowing, calling the current geometry a “deadlock.”
Conflicting Reports & Gaps
- Delay estimates vary: some commuters cite 40 minutes, others 55 minutes, and a few report over two hours. The police have not released an official average travel-time figure.
- Officials claim traffic will normalize within a week, but no quantitative forecast has been published.
What’s Next
- Physical retrofits: Police have requested PWD to place barricades or cones at the Sundial Park merge to create a gentler curvature.
- Signal installation: A ramp-metering signal at the Sundial loop is being considered to regulate inflow.
- Navigation updates: Authorities have written to Google Maps to incorporate live traffic data for the new corridor.
- Further monitoring: The Delhi Traffic Police will continue aerial surveys and adjust personnel deployment as traffic patterns settle.
