Phase 2 Information

Chennai Metro Phase 2 project with 3 new lines totaling 118.9 km was approved by the Tamil Nadu government in 2019 at an estimated cost of Rs. 69,180 crore. 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 118.9 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 and is expected to open to the public in phases from 2025 onwards. After phase 2 is built and opened in 2028 (estimated), Chennai’s metro network will become roughly 173 km long.
