The Delhi government is moving forward with an ambitious plan to expand the Delhi Metro network, aiming to ease congestion, reduce pollution, and modernize the capital. Chief Minister Rekha Gupta has emphasized the government's commitment to strengthening public transport and combating air pollution through this expansion.

The Delhi Metro Rail Transit System (MRTS) Phase IV will see the construction of three new corridors, spanning a combined length of 47.225 kilometers. These corridors are expected to be completed within four years and will significantly improve Metro connectivity across Delhi and the National Capital Region (NCR). The Delhi Government has already released ₹3386 crore for these projects.

The new corridors include:

• Lajpat Nagar to Saket G-Block: An 8.385-kilometer stretch with eight elevated Metro stations.
• Inderlok to Indraprastha: A 12.377-kilometer line with ten Metro stations, including one elevated and nine underground stations.
• Rithala to Kundli (Haryana): A 26.463-kilometer corridor extending connectivity to Haryana, featuring 21 stations.

The total cost of these projects is estimated at approximately ₹14,630.80 crore, with the Delhi Government contributing ₹3,386.18 crore. The expansion is not only aimed at improving connectivity but also at reducing traffic intensity and pollution in Delhi. By providing a reliable and efficient public transportation system, the government hopes to encourage people to shift from private vehicles to the Metro.

The Delhi Metro's expansion is part of a larger effort to improve public transportation and reduce pollution in the city. The Transport Department has been allocated 60% additional funds in the current budget to strengthen public transportation. The government is also clearing pending liabilities related to Metro projects from previous administrations.

In addition to new corridors, existing stations are being upgraded to improve connectivity. Aerocity Metro station is set to become a major interchange hub, integrating the Airport Express Line with the Tughlakabad–Aerocity Golden Line. Furthermore, structural provisions are being made for a potential interchange with the National Capital Region Transport Corporation's (NCRTC) proposed Alwar corridor, potentially making it a triple interchange station.

The Delhi Metro is also working to improve commuter convenience by renaming certain stations. For example, the Pitampura Metro Station on the Red Line will be renamed "Madhuban Chowk".

The expansion aims to increase the Delhi Metro's daily ridership. With the completion of Phase IV, the Delhi Metro is projected to serve over 6.5 million commuters daily and will be among the top five metro networks in the world, spanning over 400 kilometers.

Chief Minister Gupta has also directed officials to expedite other projects related to increasing the number of electric buses, developing smart parking solutions, redeveloping roads, and improving waste management. The Delhi government plans to increase its bus fleet to 6,000 by December 2026, with a focus on electric buses to strengthen last-mile connectivity.
