Delhi Metro Phase 4 project’s routes with 6 lines totaling 103.93 km within Delhi’s borders were finalized in July 2015. Out of this, 61.679 kms across 3 lines (priority corridors) with 45 stations were approved by India’s Central Government for construction on March 7, 2019. The Silver Line’s length was increased in October 2020, making the entire project 65.1 km long.

 

In March 2024, the central government approved the addition of 2 corridors totaling 20.76 km, taking Phase 4’s length to 85.86 km. This includes the 12.377 km Inderlok – Indraprastha extension of the operational Green Line and 8.385 km Lajpat Nagar – Saket G Block line.

Tendering for Phase 4’s civil construction began in June 2019, with piling work on Line-8’s extension commencing on December 30, 2019 at Haiderpur-Badli Mor Station.
