The Haryana Mass Rapid Transport Corporation (HMRTC) has proposed a double-decker viaduct that would carry the Sector 56–Panchgaon metro line above a planned elevated road on the Southern Peripheral Road (SPR). Officials said the idea, still at a preliminary stage, is aimed at avoiding long-term congestion, infrastructure clutter, and irreversible space constraints on a critical arterial road.
According to officials involved in the planning, constructing two separate elevated projects—one for the metro and another for road traffic—would saddle the city with decades of bottlenecks. “If we build independently, we lock the corridor forever,” a senior HMRTC official said, warning of excessive piers, reduced road capacity, visual congestion, and little room for future upgrades.
A new Vaiduct to be the solution
The proposed solution is a shared viaduct, with one deck carrying the metro line and the other the elevated road, both supported on common piers. Officials believe this coordinated approach offers the most sustainable way forward for a fast-growing city already grappling with limited rights of way.
HMRTC has identified the Ghata to Vatika Chowk stretch as the most viable location for the double-decker structure, as this is where the proposed metro alignment overlaps with an already approved elevated road project on the SPR. To assess whether the two systems can be safely and efficiently stacked, HMRTC has sought a detailed technical feasibility study from RITES, the government-owned engineering consultancy.
Metro DPR ready, road project cleared
The planned elevated line that will house the Sector 56–Panchgaon metro corridor already has a Detailed Project Report (DPR) prepared and is awaiting approval. At the same time, the Haryana government last month cleared the construction of a new flyover on the same stretch of the SPR.
Officials said both projects are vital for Gurugram’s mobility needs, but executing them separately would severely compromise the corridor. “A double-decker viaduct allows us to meet today’s demand without sacrificing tomorrow’s options,” an official said.
HMRTC officials flagged multiple risks if the projects move ahead independently, including duplicated foundations, excessive pier density, and poor access for maintenance. While the concept may seem new, it is already in use in cities such as Nagpur, Bengaluru, Delhi, and Jaipur. Officials said these examples show that integrated infrastructure not only reduces construction costs and disruption but also delivers a cleaner, safer, and more efficient urban environment.
