Namma Metro Phase 3 is progressing towards implementation. BMRCL to invite tenders for JP Nagar–Kempapura corridor in Bengaluru.

Bengaluru Metro Rail Corporation Ltd (BMRCL) cancelled three civil-work tender packages invited in January for Phase 3’s Orange Line. It scrapped the tenders after scaling back the planned end-to-end double-decker flyover and changing the project and flyover designs. BMRCL will re-estimate the project cost and issue new tenders soon; construction may be delayed until the new tender process is complete.

The project, approved by the Central government in August 2024, has a total estimated cost of ₹15,611 crore. Its two corridors total 44.65 km and have 31 stations:

• JP Nagar 4th Phase to Kempapura via Outer Ring Road West: 32 km, 21 stations.
• Hosahalli to Kadabagere via Magadi Road: 12.5 km, 10 stations.

Bengaluru Development Minister Krishna Byre Gowda laid the foundation stone for a Rs 75-crore, 125-bed government hospital at Bellahalli in Yelahanka taluk. The three-floor building will offer specialised medical services; two additional floors are planned to raise capacity to 250 beds. Two acres behind the hospital are earmarked for a future super-speciality block.

A second 125-bed hospital, also estimated at Rs 75 crore, is planned at Animal Husbandry and Agriculture Department premises in the Hebbal Assembly constituency. The facilities aim to address a healthcare gap in Byatarayanapura constituency, which spans from MS Ramaiah College and Ring Road to the Narayanapura border and Kempegowda International Airport, across Yelahanka and KR Puram taluks.

The Bellahalli hospital is expected to serve Thanisandra, Kempapura, Kogilu, Nagawara, Hegdenagar, Jalahobli, Marenahalli, Sathanur and Bagalur, as well as nearby rural and urban settlements. A 60-bed Greater Bengaluru Authority hospital at Singapura is complete and ready for inauguration. Health Minister UT Khader, MLA Dinesh Gundu Rao, public representatives and officials attended.

The Union Cabinet approved Phase 3 in August 2024 at an estimated cost of ₹15,611 crore. It comprises two elevated corridors: JP Nagar 4th Phase–Kempapura (32.15 km) along Outer Ring Road West, and Hosahalli–Kadabagere (12.50 km) along Magadi Road. The expansion will take Bengaluru’s active metro network to 220.20 km.

BMRCL expects construction to start in June 2026 and operations in May 2031. Around 1,100 trees are approved for relocation on the JP Nagar–Mysuru Road stretch; planning reduced the overall tree count from over 11,000 to about 6,700.

The project includes 10 multimodal hubs, bus bays, station parking, footbridge links to Lottegollahalli and Hebbal railway stations, and cycle-sharing. Projected daily ridership is 4.63 lakh on Corridor 1 and 1.75 lakh on Corridor 2.

BMRCL is reconsidering a proposed 37 km double-decker flyover, potentially scaling it down to 11 km at congestion points including Hebbal, BEL Circle, Goraguntepalya, Sumanahalli, Nagarbhavi, Nayandahalli, Kamakya Junction and Sarakki Junction.

Indicative property prices: Nagarbhavi–Sumanahalli, about ₹7,000/sq ft; Magadi Road–Kadabagere, ₹9,900–₹16,550/sq ft; Peenya–BEL–Hebbal, ₹8,000–₹18,400/sq ft; JP Nagar and southern Bengaluru apartments, ₹8,550–₹16,300/sq ft.

Namma Metro Phase III comprises the 45km Kempapura–JP Nagar corridor on the Outer Ring Road and Hosahalli–Kadabagere corridor on Magadi Road. The Union government approved it in August 2024; Prime Minister Narendra Modi laid its foundation stone in August 2025, but work has yet to begin.

BMRCL proposed a 37km double-decker structure along the Orange Line, with a road flyover below the Metro viaduct, estimated to cost ₹9,700 crore, to be funded by the state. Following RITES’ advice, BMRCL is considering reducing it to around 11km of shorter stretches at traffic bottlenecks and will discuss the proposal with the state government. RITES cited risks of encouraging private vehicle use and engineering and operational challenges; structures could reach 35 metres. The Metro-only project’s EIRR is about 17%, compared with below the 14% benchmark with the double-decker component.

Potential bottlenecks include Hebbal, BEL Circle, Goraguntepalya, Sumanahalli Cross, Nagarbhavi, Nayandahalli, Kamakya Junction, Sarakki Junction, the Delmia flyover stretch and Vega City Mall. BDA has proposed a six-lane tunnel from Kanteerava Studio to BEL Circle via Goraguntepalya and floated tenders for its detailed project report.
