The Karnataka Cabinet cleared 11 corridors spanning 75.6 km at an estimated ₹13,262.7 crore in April 2026: nine under PPP and two longer routes under BOT. In September 2026, the government reviewed a broader B-SMILE plan for 13 elevated and grade-separated corridors spanning about 120 km.

• Yeshwanthpur–KR Puram: 28 km, via Mathikere Cross, IISc, Mekhri Circle, Jayamahal, St John’s Church Road and Ulsoor.
• Marenahalli Main Road (Ragigudda)–Kanakapura Main Road: 18.5 km, via Pipeline Road and Thalaghattapura.
• Mysuru Road–Nayandahalli: 5.2 km; Pipeline Road–Outer Ring Road: 2 km; Tumakuru Road–MEI Junction: 0.5 km.
• Raghuvanahalli Cross: 0.9 km; Minerva Circle–Hudson Circle/Town Hall/KR Circle: 6.97 km; Kanakapura Road–Konanakunte Cross: 1.5 km.
• Old Madras Road–Silk Board: 5.2 km, via Swami Vivekananda Metro Station, Indiranagar, Old Airport Road and Hosur Road.
• Doddaballapura Road–Kogilu: 1.47 km, via Old Yelahanka; Hosur Road–Shoolay Circle: 5.3 km, via Anepalya and Adugodi.

Average flat prices: Yeshwanthpur ₹13,350/sq ft (+51.7% in three years, +113.6% in five); KR Puram ₹9,200 (+12.2% in one year, +52.1% in three); Old Madras Road ₹10,350 (+4.5% in one year, +54.5% in three); Yelahanka ₹10,950 (+16.5%, +52.1% and +90.4% over one, three and five years); Thalaghattapura ₹13,500 (+37.8% in one year, +28% in three).

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.

Nandi Infrastructure Corridor Enterprises (NICE) opened a 1.5-km, four-lane connecting road near Deepanjali Nagar Junction on Mysuru Road. It links Deepanjali Nagar Junction (BHEL Circle) to NICE Road near Hosakerehalli PES College, providing access towards Challaghatta and adjoining areas.

The project was delayed by land acquisition challenges. Before the link opened, motorists covering the 11-km Deepanjali Nagar–Challaghatta stretch during peak hours took 45 minutes to an hour, with congestion at Nayandahalli, R.R. Nagar, Jnanabharathi and Pattenagere. Travel time to Challaghatta is now expected to be around 30 minutes.

NICE promoter Ashok Kheny posted a drone image of the stretch on X on March 16. The road opened to the public on March 20, 2026.

Nandi Infrastructure Corridor Enterprises (NICE) is set to open a newly built 1.5-km, four-lane road linking Deepanjali Nagar junction (BHEL Circle) on Mysuru Road directly to NICE Road near Hosakerehalli PES College. The link forms part of the Bangalore-Mysore Infrastructure Corridor (BMICP) and is expected to improve access towards Challaghatta and adjoining areas.

Work was delayed by land acquisition issues. During peak hours, the 11-km journey from Deepanjali Nagar junction to Challaghatta currently takes 45 minutes to an hour. Nayandahalli, R.R. Nagar, Jnanabharathi and Pattenagere junctions frequently face congestion, especially at traffic signals. The new link is expected to cut travel time to Challaghatta to around 30 minutes.

NICE promoter Ashok Kheny said in a post on X dated February 21, 2025, that the stretch would soon be ready for commuters.
