Phase 3 Information

Bangalore (Namma) Metro’s Phase 3 project is currently in the proposal stage with two elevated routes totaling 44.65 km planned in western Bengaluru, Karnataka. The project is currently awaiting the Central Government Cabinet’s approval.

Bangalore Metro’s Phase 3 has been on the drawing board with 105.55 km of routes being explored since 2015. Pre-feasibility and techno-economic feasibility studies by RITES and BMRCL were prepared in 2016.

Construction on Bangalore Metro’s Phase 3 with 2 lines is expected to begin in 2026 and end in early 2030s. Another 37 km new corridor connecting Hebbal and Sarjapura will be taken up under Bangalore Metro’s Phase 3A project.
