Phase 2 Information

Chennai Metro Phase 2 project with 3 new lines totaling 116.1 km was approved by the Tamil Nadu government in 2019 at an estimated cost of Rs. 69,180 crore. Since then, the cost has been revised down to Rs 61,843 crore by reducing station sizes. The Central Government’s approval is currently pending.

Phase 2’s Detailed Project Report (DPR) was prepared by RITES and finalized in December 2018. Out of 116.1 km, 52.01 km of Line-3’s section between Madhavaram – Sholinganallur and Line-5’s section between Madhavaram – CMBT will be built on priority and partially funded by the Japan International Cooperation Agency (JICA) through an ODA loan.

Tendering for this mostly underground phase began in January 2020.

Chennai Metro Phase 2 is expected to be completed and opened in phases from 2026 onwards. After phase 2 is built and completed in 2030 (estimated), Chennai’s metro network will become roughly 173 km long.

  • CMRL’s Phase 2 Deadline: December 2025
  • My Completion Estimate: June 2030
