Bangalore Metro Phase 3 – Information, Route Maps, Tenders & Updates
Phase 3 Information
Bangalore (Namma) Metro’s Phase 3 project is currently in the planning stage with routes totaling 105.55 km being explored since 2015.
Pre-feasibility and techno-economic feasibility studies by RITES and BMRCL were prepared in 2016. Karnataka’s state government approved the preparation of the project’s detailed project report (DPR) in February 2018 and the work for it was assigned to RITES in July 2020. The first draft is expected to get ready by mid-2021.
Construction on Phase 3 is expected to begin in 2025 and end in the mid 2030s. By the time construction begins, multiple changes in the project’s scope & alignment can be expected to take place.
- Estimated Cost: N/A (Pending Route Finalization & Approval)
- BMRCL’s Current Phase 3 Deadline: Not Finalized (Pending Route Finalization & Approval)
- My Completion Estimate: 2035 (no sooner, if approved by state government in 2024)
- Carmelaram – Yelahanka (32 km, shown in Brown)
- Marathahalli – Hosakerehalli (21 km, shown in Red)
- Silkboard – KR Puram – Hebbal (29 km, shown in Blue)
Note: The 18 km Silkboard – KR Puram section (view info & DPR) has been fast-tracked and allocated to Phase 2A. In March 2017, the Karnataka Government’s cabinet approved its DPR.
Note: Official line colors are yet to be announced.
Extensions of Existing Lines
- Nagavara – Airport (23 km)
Note: In May 2017, the airport line’s route was finalized via RK Hegde Nagar – Jakkur – Yelahanka – see info here. In 2018, it was decided to be developed under Phase 2B as an extension of the Silkboard – KR Puram line instead.
In addition, here are some other potential lines on the drawing board –
- JP Nagar to K R Puram via Hebbal
- Magadi Road Toll Gate to Kadabagere
- Gottigere to Basavapura
- RK Hegde Nagar to Aerospace Park
- Kogilu Cross to Rajanukunte
- Bommasandra to Attibele
- Iblur to Carmelaram
In March 2020, Karnataka’s Chief Minister announced during the budget speech that 2 corridors will be developed as metrolite lines through the public private partnership (PPP) model and the Detailed Project Report (DPR) for both will be prepared. These 2 corridors are:
- ORR West Line: Hebbal to Mysore Road Metro Station (30 km)
- Magadi Road Toll Gate to Kadabagere (14 km)
NOTE – An accurate representation of Phase 3 will appear only after the DPR is finalized and approved. Until then, all of the above lines and extensions are contenders for inclusion – see my post here which includes a map of the above lines.
