The Delhi Metro Rail Corporation (DMRC) is making significant strides in urban infrastructure with the construction of three double-decker viaducts as part of its Phase 4 expansion. These innovative structures will seamlessly integrate metro rail and road traffic, setting a new benchmark for efficient and sustainable urban mobility.
An Ambitious Integration of Delhi Metro and Road Systems
The double-decker viaducts are being built along three priority corridors:
Majlis Park-Maujpur Corridor
Aerocity-Tughlakabad Corridor
Janakpuri West-RK Ashram Marg Corridor
These structures aim to reduce congestion, enhance connectivity, and make commuting faster and more convenient for Delhi residents. According to Anuj Dayal, DMRC’s principal executive director, these rail-cum-road flyovers will optimize land use while streamlining traffic flow in some of the busiest areas of the city.
DMRC Double-Decker Viaduct Projects
1. Majlis Park-Maujpur Corridor: Bhajanpura-Yamuna Vihar Section
Structure Details:
A double-decker viaduct featuring a Public Works Department (PWD) flyover on the lower deck and a metro line on the upper deck.
Current Progress:
The metro-level structure is complete, excluding road ramps, which are pending tree-cutting permissions. Once approvals are in place, ramp construction will proceed.
2. Aerocity-Tughlakabad Corridor: Ambedkar Nagar T Point
Structure Details:
The first double-decker viaduct in South Delhi, featuring a road flyover on the lower level and a metro line above it.
Construction Updates:
Pier cap launching for the metro track is ongoing.
Crossbeam installation for the road flyover is in progress.
Unique Feature:
This section will be a landmark for South Delhi, providing an efficient transit solution in a densely populated area.
3. Janakpuri West–RK Ashram Marg Corridor: Azadpur to Ashok Vihar
Structure Details:
A 630-metre-long double-decker viaduct.
Progress:
Foundation work is nearly complete, and pier work is in its final stages. This section is expected to play a key role in decongesting traffic in North Delhi.
Phase 4 Expansion: Enhancing Connectivity
The Phase 4 expansion is a major undertaking for the DMRC, involving: A 65-kilometre metro network.
45 new stations spread across the three priority corridors:
Janakpuri West–RK Ashram Marg (28.92 km).
Majlis Park-Maujpur (12.55 km).
Aerocity-Tughlakabad (23.62 km).
Despite delays caused by the COVID-19 pandemic and challenges with tree-cutting permissions, the DMRC remains on track to complete this ambitious project by 2026.
Benefits of the Double-Decker Viaducts
Space Optimization:
Double-decker structures maximize vertical space, a crucial factor in densely populated areas like Delhi.
Reduced Traffic Congestion:
By integrating metro lines and road flyovers, these viaducts alleviate surface-level traffic bottlenecks.
Sustainability:
Efficient design minimizes land acquisition and environmental disruption.
Time Savings:
Commuters can expect faster, more streamlined travel experiences, both on the metro and on the road.
Challenges and Future Prospects
While construction progress is promising, challenges like environmental approvals and urban congestion require ongoing management. Once completed, these viaducts will not only revolutionize Delhi’s metro infrastructure but also serve as a model for urban transit solutions across India.
