Civil society, affected communities, and unions submitted a formal petition to Deputy PM Ek Niti requesting scrutiny of the Double-Deck Expressway project (Ngamwongwan–Rama IX). Concerns focus on lack of transparency in contract terms, inadequate environmental impact assessment (EIA) public engagement (~600 residents signed opposition), safety risks especially post-earthquake, and questionable cost-benefit (35B baht government investment vs. 170B+ baht long-term loss). Communities face relocation pressure; unions emphasize incomplete contract disclosure. The Deputy PM's response will shape a major PPP project affecting Bangkok infrastructure and public welfare.
