As cities in India grapple with growing traffic congestion, infrastructure innovators are turning to advanced solutions like double-decker flyovers—multi-tiered elevated highways designed to ease traffic and enhance urban mobility.

What Is a Double-Decker Flyover?

A double-decker flyover features two elevated road levels stacked vertically. The upper tier often serves high-speed or express traffic, while the lower deck handles local connectivity. This stacked flyover design optimizes space, especially where ground-level expansion is impractical.

Why These Structures Matter

• Space-Efficient Infrastructure: Ideal for dense urban environments facing limitations in land acquisition.

• Improved Traffic Flow: By separating express and local traffic, these structures boost throughput and reduce congestion.

• Faster Commutes & Fuel Efficiency: Streamlined routing directly translates into reduced travel time and vehicle emissions.

• Modern Urban Aesthetics: Incorporating noise barriers, LED lighting, and landscaping, these flyovers can enhance cityscapes as functional architectural elements trafficinfratech.com.

Landmark Projects: India’s Pioneering Double-Decker Flyovers

• Santacruz–Chembur Link Road (Mumbai): Home to India's second-ever double-decker flyover, this project spans 6.45 km and addresses traffic over congested junctions Wikipedia.

• Patna’s Ashoka Rajpath Flyover: Inaugurated on June 11, 2025, this three-tier flyover system merges the highway tier, metro rail line, and a service roadway—enhancing connectivity across Patna’s academic and institutional belt The Times of India.
