Delhi Metro Phase 4 – Information, Route Maps, Tenders & Updates

Phase IV Information

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.
