The Delhi government has approved three new corridors under Delhi Metro Phase 5, marking a major boost to the capital’s public transport network. The project, estimated to cost Rs 12,014 crore, is targeted for completion by 2028. The total length of the new lines will be 16.1 km.

The approved corridors are extensions of existing metro lines and are designed to enhance connectivity across Central Delhi, South Delhi, and the airport, while also helping to reduce road congestion and air pollution in the national capital.

Spanning around 89 kilometres, the Magenta Line (Line-8) of the Delhi Metro network is set to emerge as the longest corridor of the Delhi Metro, featuring the highest number of interchange stations and underground stations, thereby significantly enhancing cross-city connectivity across the national capital region, according to the Delhi Metro Rail Corporation (DMRC).

Following the sanction of Phase V (A), the extension of the Magenta Line from Ramakrishna Ashram Marg to Indraprastha via Central Vista will be taken up. The Indraprastha–Inderlok corridor under Phase IV will also be implemented as an extension of the Magenta Line, it said.

With these additions, the total length of the Magenta Line, from Botanical Garden to Inderlok, will be around 89 kilometres, making it the longest corridor in the Delhi Metro network. Once fully operational, the entire stretch will function as a driverless corridor.
