The Bangalore Metro Rail Corporation Corporation Limited (BMRCl) Hebbal-Sarjapur, part of the Expansion of Phase 3a and is called the Red Line, is a 36.59 km project to connect Sarjapur in the southeast of the city with Hebball in the north. The project is currently facing re -evaluation of costs.
According to BMRCL, the line is expected to be the most expensive in the history of the Namma Metro with an estimated cost of 28 405 Crore, which represents approximately 776.3 crore per km. Karnataka Cabinet cleaned the design in December 2024 and the project is currently under the control of the Ministry of Housing and urban affairs (I can).
Officials confirmed that the ministry has returned a detailed report on the project (DPR) to the State Government and the aim of reviewing the costs according to the Benchmark instructions. Since the Center has a 50% share in the Namma subway, the state asked the state to appoint an independent consultant to re -evaluate and rationalize expenses. “In the process of re -evaluation of costs with an external consultant according to the instructions,” said sources in BMRCL.
The red line is designed to pass through prominent urban zones, including Agar, Korangala, Dairy Circle, Belllandur, St. John’s Hospital, Nimhans, Central College, Cunningham Road and Mehkri Circle. Almost 16.8 km of the line that stretches from the Korangala to Hebal will be underground. The increased part that runs between the 3rd block Sarjapur and the Koramangala will host 15 stations, while the underground part between the 2nd Block of the Koramangala and the Veterinary Higher School will contain 11 stations.
The preliminary period of the project is December 2030, although officials suggest that it can expand to 2031 depending on the timeline of approval. The forgiveness of the center is expected only until the end of 2025, after the re -evaluation is completed.
The acquisition of soil forms an important part of the project expenditure, with BMRCL estimating the cost of approximately 8,080 GBP Crore for this process. A total of 161.65 acres are required, including 55.69 acres of private land identified near Sarjapur Circle for the proposed depot.
After operation, according to officials, the red line is expected to significantly alleviate mobility across technology nodes and the residential areas of the city.
