Phase 3A of Bangalore Metro approved by Government of Karnataka

The Cabinet of the Government of Karnataka today approved the detailed project report (DPR) of 36.59 km of Bangalore Metro Phase 3A at an estimated cost of Rs. 28,405 crores.

Bangalore Metro Rail Corporation Ltd.’s (BMRCL) Phase 3A project will comprise a new metro line connecting Sarjapur – Hebbal via 28 stations. This line with 22.14 km of elevated sections and 14.45 km underground will pass through the city center and connect Carmeleram, Agara, Koramangala, Dairy Circle, Central College and Armane Nagar.

The Phase 3A Presidential Decree was prepared by RINA Consulting SpA for the BMRCL in the period 2022-2023. It is suggested to construct a train maintenance depot and stables at Sarjapur.

28 stations (17 elevated and 11 underground) are planned to be constructed at Sarjapur, Kada Agrahara Road, Sompura, Dommasandra, Muthanallur Cross, Kodathi Circle, Ambedkar Nagar, Carmelaram, Doddakanalli, Kaikondrahalli, Bellandur Gate, Ibbalur, Agara, Jakkasandra, Koramangala 3rd block, Koramangala 2nd block, Dairy Circle, Nimhans, Shantinagara, Town Hall, KR Circle, Basaveshwara Circle, Bengaluru. Golf Course, Guttahalli Palace, Mekhri Circle, Veterinary College, Ganga Nagar and Hebbal.

5 stations will provide interchange connectivity to Ibbalur (Blue Line), Agara (Blue Line), Dairy Circle (Pink Line), KR Circle (Purple Line), Hebbal (Blue Line and Orange Line).

The line will run underground between Veterinary College and Koramangala 3rd block. This line will probably consist of two double-decker viaducts for vehicles and metro trains:

• Sarjapur to Ibbalur (ORR Junction) of 14 km length (CH: 0.500 Km to CH: 14.500 Km)
• From Agara to Koramangala 3rd block of 2.45 km length (CH: 16,900 Km to CH: 19,350 Km)

With this exciting development, BMRCL is now expected to commence pre-construction and other tendering activities to appoint Detailed Design Consultants (DDCs) and contractors for shifting and demolition services post land acquisition.

The DPR will now be sent to the Union government for approval of its various departments and cabinet. Tendering for civil construction may begin before approval from the Union government, but contracts will be awarded only after approval, as per phase 2A and 2B. At this time I expect construction work to begin no earlier than 2027.
