The DPR (Detailed Project Report) for Phase 2 is expected to be finalized by 2026–2027.
When will Patna Metro Phase 2 start construction?
Patna Metro Phase 2 construction is expected to begin after Phase 1 operations are fully stabilized, likely in 2027–2028. The Phase 2 route alignment, station locations, and detailed engineering are still being planned by PMRCL and the Bihar Government.
How many new stations will Patna Metro Phase 2 have?
The exact number of Phase 2 stations is not yet finalized. Proposed Phase 2 extensions could add 15–25 new stations, extending the metro network by approximately 20–30 km. Final details will be released when the DPR is approved by the central government.
