Delhi Metro Phase 4: DMRC begins construction work on Inderlok-Indraprastha corridor

Inderlok-Indraprastha Metro corridor: The Delhi Metro Rail Corporation (DMRC) has started construction work on the Inderlok-Indraprastha Corridor, which is part of the Phase 4 expansion project. The 12.377 km-long corridor marks a significant addition to the Delhi Metro network. The construction work began with the initiation of Diaphragm Wall construction at the Sarai Rohilla Metro Station site in the national capital. The work started in the presence of Chief Minister Rekha Gupta.

The corridor was approved by the Union Cabinet in March 2024, and the foundation stone for the project was laid by Prime Minister Narendra Modi in the same month. The Inderlok-Indraprastha Corridor is targeted for completion by December 2030.

About Sarai Rohilla Metro Station

The proposed Sarai Rohilla Metro Station is set to become one of the important stations on the Inderlok-Indraprastha Corridor of the Magenta Line. Strategically located in central Delhi, the station is expected to provide improved connectivity to several educational institutions, cinema halls, the Karol Bagh market, Desh Bandhu Gupta Road, and other important destinations in the surrounding areas.
