Bengaluru’s 37km double-decker flyover gets 90% public support, BMRCL to finalise design soon

Amid the tunnel road controversy, BMRCL’s proposed 37km double-decker flyover, combining road and Metro levels, gains massive public approval, with 9 out of 10 commuters ready to pay tolls to ease traffic congestion.

As Bengaluru debates the tunnel road project, a potential solution to the city’s crippling traffic may soon rise above ground, quite literally. The Bangalore Metro Rail Corporation Limited (BMRCL) has received overwhelming public backing for its proposed 37km double-decker flyover project, which will feature a road flyover and Metro line built on separate levels along the same stretch.

According to a commuter survey conducted by BMRCL through Hyderabad-based Aarvee Engineering Consultants, nearly 90% of the 1,000 respondents expressed support for the initiative and said they were willing to pay a toll if it helps reduce daily traffic congestion.

The project is planned along two major corridors, JP Nagar 4th Phase to Hebbal, and Hosahalli to Kadabagere, as part of Namma Metro Phase III. It is expected to be the longest double-decker corridor in Bengaluru, combining the efficiency of Metro travel with improved road connectivity.

BMRCL has pegged the total cost of the project at ₹9,692 crore, including ₹3,023 crore for land acquisition. The road flyover portion alone will cost around ₹261 crore per kilometre. The structure will feature four lanes, two in each direction, with entry and exit ramps at key junctions for smooth traffic movement.

The double-decker flyover is designed to support speeds of up to 80 kmph, with a minimum operational speed of 40 kmph. The feasibility study highlights that the project will significantly decongest Bengaluru’s busiest corridors, particularly the Outer Ring Road (West) section, which is expected to gain direct connectivity to the airport.

Traffic and pedestrian movement data underline the urgency of such infrastructure. The Hebbal junction currently records the highest pedestrian flow in the city, 5,642 people per hour, while vehicle density at several junctions already crosses 10,000 passenger car units (PCUs) per hour, far exceeding capacity.

The project’s economic analysis also suggests a positive rate of return, making it financially feasible. BMRCL officials confirmed that the final design is being prepared, and tenders will be floated soon.
