After CM Basavaraj Bommai announced a new 37 km metro line connecting Sarjapur and Hebbal at around Rs 15,000 crore, Bengaluru Metro Rail Corporation Limited (BMRCL) floated a tender to prepare its detailed project report (DPR).

The new rail corridor will connect Sarjapur to Hebbal through Agara, Koramangala and Dairy Circle. According to the tender document, the DPR must be prepared within eight months, and the deadline to submit bids is 16 May.

The DPR will provide details, including alignment, underground and elevated sections, several stations, locations, depot, rolling stock requirement, projected ridership, estimated cost, etc.

The route is expected to be completed by 2027-2028. The stretch of the Hebbal-Koramangala will be underground and elevate the rest.

Rail India Technical and Economic Service (RITES) is preparing a DPR for two priority Phase 3 corridors, the 34 km Hebbal-JP Nagar and 13-km Hosahalli-Kadabagere lines, with an estimated cost of Rs 11,250 crore, which will be submitted to the central government for approval.

The Centre is likely to approve all three Phase 3 metro corridors ahead of the assembly elections in Karnataka in 2023.
