Double-Decker Flyover From JP Nagar to Hebbal Wins 90% Support, Seen as Better Option Than Tunnel Road

As debates over Bengaluru's proposed tunnel road continue, another ambitious project is gaining traction - a 37 km double-decker flyover that could redefine the city's traffic landscape. The Bangalore Metro Rail Corporation Limited (BMRCL) has proposed a dual-level corridor, featuring a road flyover and a Metro line running on separate levels, stretching from 28.4-km JP Nagar-Kempapura route in Hebbal and an 8.6-km elevated section from Hosahalli (Magadi Road) to Kadabagere

According to a commuter survey conducted by Hyderabad-based Aarvee Engineering Consultants for BMRCL, nearly 90% of respondents said they were willing to pay a toll if the project helps reduce congestion on the city's major roads. The survey covered over 1,000 people and revealed strong public preference for this elevated solution over the tunnel road plan.

A Game-Changer for Bengaluru's Traffic

The double-decker flyover aims to ease bottlenecks along the Outer Ring Road (West), connecting southern and northern parts of Bengaluru more efficiently. The project is part of Namma Metro Phase 3 and is expected to be the longest double-decker corridor in the city.

The BMRCL has estimated the total project cost at ₹9,692 crore, including ₹3,023 crore for land acquisition. The road section alone is expected to cost ₹261 crore per kilometre. The structure will have four lanes, two in each direction, with entry and exit ramps at major junctions to ensure smooth traffic flow.

Designed for speeds between 40 kmph and 80 kmph, the elevated corridor will significantly reduce travel time for daily commuters and airport-bound traffic. The project also includes Metro connectivity on the upper deck, making it a comprehensive mobility corridor.

Why the City Needs It

Traffic data highlights the urgency for such infrastructure. At Hebbal Junction, one of the city's busiest points, around 5,642 pedestrians cross per hour, while vehicle density crosses 10,000 passenger car units (PCUs) during peak hours.
Officials said the new corridor will not only decongest these choke points but also serve as a faster, safer alternative for airport and intercity connectivity.

Public Backs Elevated Solution Over Tunnel

The strong response to the double-decker flyover comes at a time when the tunnel road proposal has faced criticism for its environmental and cost concerns. Many residents believe that an elevated structure, combining road and Metro systems, offers a more sustainable and practical solution.

BMRCL officials confirmed that the final design is being prepared and tenders will be floated soon. Once completed, this project could become one of Bengaluru's most significant infrastructure achievements, providing a futuristic model for urban mobility in India.
