Delhi's Double Decker Bridge Expecting Completion By 2024; To Run Between Aerocity-Tughlakhabad Corridor Of Metro Phase-4

The construction of the double-decker viaduct in south Delhi running along the Mehrauli Badarpur Road is expected to be completed by the end of 2024, as stated by Delhi Metro Rail Corporation (DMRC) officials.

This elevated corridor will consist of a six-lane flyover with a metro corridor built above it.

As per Hindustan Times report, DMRC said that the metro viaduct will be on the upper deck, at a height of 18 m from the ground.

Additionally, a 2.4 km elevated road will be constructed on the lower deck, at a height of 9.3 m.

This flyover on the lower deck will start at the proposed Sangam Vihar Metro station and end near the proposed Ambedkar Nagar Metro station, while a road will also be present at the ground level.

The double decker project is part of the phase-4 expansion of the Delhi metro under DMRC, which includes the new Silver Line corridor — built between Aerocity and Tughlakabad.

Anuj Dayal, principal executive director, corporate communication, DMRC expressed, “The construction of the double decker viaduct at the Ambedkar Nagar T-Point on the Aerocity-Tughlakabad corridor of phase 4 is progressing at good pace, and the first double height pier for this section has been cast.

The double decker viaduct is likely to be ready by the end of 2024. This shall be South Delhi’s first such construction where a Metro line and a road flyover are being constructed one below the other,” as per the report.

While the deadline for the entire corridor is set for September 2025, officials have indicated that the construction of the flyover will be completed much earlier and handed over to the Public Works Department for operations.

Dayal further added, “This will be one of the most challenging engineering projects for DMRC since the space available for construction work here is extremely narrow. The launching work shall also be done at two levels for the road flyover and the metro viaduct, which will also be a challenge,”

In addition to this infrastructural development, DMRC is building more such double decker viaducts as part of its phase-4 metro expansion.

This includes the 1.4 km flyover and metro viaduct in the north east region of Delhi — on the Majlis Park-Maujpur section of the Pink Line.

This will be on the central verge of the road running between Bhajanpura and Yamuna Vihar. The respective stations will come up at a height of 18.5 m, in an earlier report by Times of India.

The width of the metro viaduct is 10.5 m and the flyover will be 10 m wide, having three lanes.  

With this elevated connectivity, the travel between Northeast Delhi and mid-Delhi will get easier. The distance between Bhajanpura-Gokulpuri will also become traffic free.
