A new US$1.47 billion underground expressway route is being proposed for Thailand’s traffic-choked capital, Bangkok. Building the 6.3km underground tunnel stretch for part of the N1 Expressway project could help alleviate the city’s chronic traffic congestion, which is amongst the worst in the world.
However, the proposals have met with some resistance from locals. Building an elevated expressway stretch instead would cost around $500 million. An environmental study will be carried out in 2025. Should the project get approval, construction would start in 2026 with completion expected by 2031.
