Bengaluru: In 2025, Karnataka has embarked on a transformative series of infrastructure projects focused on modern urban mobility, especially in Bengaluru. Among the most ambitious are the construction of the city’s first double-decker flyovers and a significant expansion of the metro network. These initiatives aim to decongest traffic, improve connectivity, and support rapid urban growth.

Double-Decker Flyovers

  • The flagship is the Ragigudda–Central Silk Board double-decker flyover, now open for vehicles. This 5.12 km, ₹449 crore structure features two decks: the upper for the Metro’s Yellow Line, the lower for vehicular traffic.
  • This corridor is signal-free, primarily easing bottlenecks at the Central Silk Board junction and connecting HSR Layout, Ragigudda, and Hosur Road. Projected travel time reductions exceed 30% for critical routes in South Bengaluru.
  • Ramps and loops are being constructed to integrate seamlessly with arterial roads; final connections are expected to be functional by mid-2025.
  • The city administration has set a goal to construct a further 150 km of flyovers and signal-free corridors under its urban renewal agenda.
Innovative Engineering: The double-decker model integrates metro rail infrastructure above roadways, optimizing limited urban space and enabling efficient multi-modal transit.

Metro Expansion

  • By June 2025, Bengaluru’s metro network will reach 175 km, with major segments on track for completion, especially the Yellow Line (R.V. Road to Bommasandra).
  • The Yellow Line includes 16 stations and integrates with the double-decker flyover at Jayadeva Junction, one of India’s busiest urban intersections. This area is being redesigned to host a six-level interchange with road and metro lines.
  • The state has approved Phase 3 of the Metro, eyeing 314 km of network by 2041. Upcoming priorities include extended suburban connections and an airport link.
  • Investments also focus on improving last-mile connectivity and digital ticketing, aiming for an integrated public transport system.

Expected Impact

  • Reduced Travel Time: Signal-free flyovers and Metro integration will reduce congestion and cut commutes by over 30% in several key corridors.
  • Improved Urban Connectivity: Enhanced Metro coverage and elevated roadways promise better access for millions across city zones.
  • Model for Other Cities: Bengaluru’s approach to space-efficient infrastructure could serve as a template for rapidly growing Indian metros facing urban space constraints.

Conclusion

2025 marks a major leap for Karnataka’s urban future, with these high-profile infrastructure initiatives positioned to shape Bengaluru’s cityscape for decades. Their success will depend on timely execution, careful planning, and continued investment in smart urban mobility solutions.
