New Delhi: The Union Cabinet, chaired by Prime Minister Narendra Modi, on Thursday approved the Delhi Metro Phase-4 project which comprised of three priority corridors. This Metro Phase project will be implemented by Delhi Metro Rail Corporation Limited (DMRC), the existing 50:50 Special Purpose Vehicle (SPV) of the Government of India and Government of National Capital Territory of Delhi (GNCTD).

Here is all you need to know about DMRC Project:

1) The Delhi Metro phase-4 consists of three priority corridors with a total length of 61.679 km. Out of the total length, 22.359 km is reserved for underground construction and 39.320 km will be built as an elevated section.

2) The Delhi Metro phase-4 consists of 17 underground stations and 29 stations on the elevated sections.

3) The estimated cost of the three metro corridors upon completion would be Rs 24,948.65 crore.

4) The Aerocity to Tughlakabad corridor has connectivity to the Delhi airport. It consists of 15 stations namely Aerocity, Mahipalpur, Vasantkunj Sector-D, Masoodpur, Kishangarh, Mehrauli, Lado Sarai, Saket, Saket G Block, Ambedkar Nagar, Khanpur, Tigri, Anandmayee Marg Junction, Tughlakabad Railway Colony and Tughlakabad.

5) The RK Ashram to Janakpuri West corridor consists of 25 stations namely RK Ashram, Motiakhan, Sadar Bazar, Pulbangash, Ghanta Ghar/Sabzi Mandi, Rajpura, Derawal Nagar, Ashok Vihar, Azadpur, Mukundpur, Bhalaswa, Mukarba Chowk, Badli Mor, North Pitampura, Prashant Vihar, Madhuban Chowk, Deepali Chowk, Pushpanjali Enclave, West Enclave, Mangolpuri, Peeragarhi Chowk, Paschim Vihar, Meerabagh, Keshopur, Krishan Park Extension and Janakpuri West.

6) The Maujpur to Mukundpur corridor consists of six stations namely Yamuna Vihar, Bhajanpura, Khajuri Khas, Soorghat, Jagatpur Village and Burari.

7) Upon completion of the project, the total network length of the Delhi Metro will cross the 400-kilometre mark.

The Delhi Metro network will expand as the corridors of the phase- 4 project will connect more areas of the national capital. Moreover, the Metro commuters will likely have more interchange stations that will connect the three new corridors with the existing lines of Delhi Metro. This leads to optimisation of routes, better connectivity and more travel options for commuters. Besides, these new corridors will help reduce road traffic and will subsequently reducing the air pollution caused by motor vehicles.
