Consumer groups, affected residents, and labor unions petitioned the Deputy PM and Finance Minister to review the Double Deck Expressway concession extension (22 years, ~35 billion baht outlay) before approval. They cite three main concerns: lack of transparency in contract terms (officials resisted full disclosure), poor cost-benefit (potential 170+ billion baht long-term loss vs. only 5–10% traffic relief), and severe community impact (safety hazards, displacement of families). ~600 residents oppose the project; EIA consultation was reportedly sparse. The petition urges thorough scrutiny before PPP committee sign-off.
