What it is
The highway department, not the expressway authority, studied six models from March 2025 for an elevated road on the west side of Route 121, 20.857 km. Model five was preferred at about 2,000 million baht, 1,000 to build, 500 for land and 500 to operate, about two and a half years, with congestion cut by more than half; the objection recorded is that it may block the view of Doi Suthep. An initial and then a full environmental assessment are required. Separately the department held a hearing on redesigning the canal road for congestion.
