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.
Delhi Metro’s Inderlok-Indraprastha corridor: Full list of stations
The Inderlok-Indraprastha Metro corridor is being developed as a fully underground extension of the Magenta Line (Line-8). It will feature 10 underground stations, further expanding Delhi Metro’s underground network. These are:

- Delhi Sachivalaya
- IG Stadium
- Delhi Gate
- New Delhi

Once completed, the Magenta Line is set to become the longest corridor of the Delhi Metro network, with the highest number of interchange stations and underground stations. According to DMRC, the route is very important as it provides interchange facilities for seven lines:

- Magenta Line at Nabi Karim Station.
- Yellow Line and Orange Line at New Delhi Station.
- Violet Line at Delhi Gate Station.
- Blue Line at Indraprastha Station.

The project will be executed through multiple major civil contract packages. The contract for one of the packages, D2C-06, has already been awarded, while the tendering process for the remaining packages is at an advanced stage, with finalisation underway.
The corridor connects seamlessly with the existing Delhi Metro network at 5 interchange stations, enabling access to a total of 7 metro lines.
