History

BMRCL began planning Namma Metro Phase-III in 2013, shortly after announcing Phase-II, which included the Yellow Line and Pink Line. Later in June 2013 BMRCL partnered with RITED Limited to conduct a pre-feasibility study for each proposed corridor

By 2016, BMRCL submitted its Phase-III proposal to the Ministry of Urban Development, which initially spanned 150.94km. However, following the feasibility the network size was reduced to 102km, with the remaining corridors being planned for Light Rail. The proposed lines were

• Nagavara - Kempegowda International Airport
• Carmelaram - Yelahanka
• Marathahalli - Hosakerehalli
• Silkboard - Hebbal via KR Puram.

However, in 2017 the Karnataka Government announced that the Silkboard - Hebbal line and the Nagavara - Airport line were merged to create the Blue Line and fast tracked to Phase 2A and Phase 2B.

In 2018 the Karnataka Government officially confirmed Phase III with several modifications. Multiple new lines were introduced while some others were dropped. Following another round of modifications in 2020, only two lines were finalized to be part of Phase-III

• Magadi Road Toll Gate to Kadabagere line
• JP Nagar to Kempapura

In July 2020, RITES Limited was assigned to prepare the Detailed Project Report (DPR) work for Phase-III. RITES submitted the DPR to the State Government who approved it in November 2022. The final approval was received from the Central Government in August 2024 paving the way for BMRCL to start land acquisition and tender notification.

Tendering

As of January 2025 BMRCL has issued tenders for Geotechnical Investigations and Detailed Design Consultancy (DDC). Once the Geotechnical Investigations are finished and finalized with the DDC BMRCL plans to release the Civil Work Tender.
