The Central Government’s cabinet in April approved the Blue Line’s construction in Phase 2A and 2B, and a bulk of the funds for it will be sourced through loans from the Asian Development Bank (ADB) and Japan International Cooperation Agency (JICA).
Utility diversion, demolition and other pre-construction activities have been underway since 2019 by small-time contractors, but additional work will be required by both contractors.
With this exciting development, I’m expecting basic site preparation work to start in Q3 2021 with full fledged construction work in Q4 2021. The state government has set a June 2025 deadline for starting commercial operations, which to me is highly aggressive and not attainable.
