Namma Metro Phase 2A: Central Silk Board to KR Puram

Phase 2A is a 19.75 km, 13-station elevated Blue Line section along the Outer Ring Road IT corridor, from Central Silk Board to KR Puram, approved by the Union Cabinet in April 2021 together with Phase 2B at ₹14,788.101 crore. Afcons Infrastructure and Shankaranarayana Constructions began civil work in mid-2021 on 30-month contracts; the opening has since moved from 2021 (2016 DPR) to about mid-2027, with October 2026 trial runs skipping the unfinished Marathahalli and Silk Board stations. Main evidence gap: no Phase-2A-specific cost, progress, or contractor delay figures are public — the sanctioned cost and the 72.75% progress both combine Phases 2A and 2B.
