Delhi’s three under-construction double-decker corridors are unlikely to open to traffic this year, with work now expected to extend into 2027, according to a report by Live Hindustan – NCR. The Delhi Metro Rail Corporation had targeted completion by December, but has not announced a revised deadline.
The corridors are being built along three Phase IV metro routes and are designed to combine elevated metro infrastructure with road flyovers below. Their delayed completion means motorists and commuters in several parts of northeast, south and northwest Delhi may have to wait longer for the planned road capacity and transport links.
The first project is a 1.4-kilometre double-decker corridor between Bhajanpura and Yamuna Vihar on the Majlis Park–Maujpur corridor. Metro services between Majlis Park and Maujpur have already started, but the road flyover below the metro viaduct is not yet ready for vehicles. The flyover’s viaduct was completed earlier, while construction of its ramps was delayed because permission for tree felling took time.
After the required approval was received, the DMRC began ramp construction with the Public Works Department in March-April this year. The report said the flyover could open to vehicles in the next few months, although the work is not yet complete. This corridor is therefore closer to operation than the other two projects, but its opening remains dependent on finishing the ramps and related works.
The second double-decker corridor is being built between Sangam Vihar and Ambedkar Nagar on the Golden Line, or the Aerocity–Tughlakabad corridor. It will be approximately 2.4 kilometres long. Work on its pillars is nearly complete and deck-slab construction is under way. The metro viaduct is expected to be completed within five to six months, but the road flyover beneath it will require more time.
The third project is located between Azadpur and Derawal Nagar on the Janakpuri West–R.K. Ashram corridor, also known as the Magenta Line extension. The combined metro-and-flyover section covers 2.2 kilometres, of which 880 metres will be a double-decker structure. Its completion is also now expected next year.
According to the report, the Azadpur–Derawal Nagar double-decker section is about 85% complete. The Sangam Vihar–Ambedkar Nagar corridor is also approximately 85% complete. However, the remaining work includes structural and road components that cannot be brought into operation simply by completing the metro viaduct above them.
The projects illustrate the coordination demands of building two transport systems within the same urban corridor. The metro structures are being executed by the DMRC, while road-related work involves the PWD. In Bhajanpura, the delay in securing tree-felling permission directly affected the construction of access ramps, showing how approvals for one component can hold back the public use of an otherwise largely completed structure.
The DMRC has not yet issued a new completion schedule for all three double-decker corridors. Until revised timelines are formally announced, the opening of the projects remains an expectation rather than a confirmed date.
