The M6 Bang Pa-in–Pak Chong expressway section (110 km) opened for trial operation on Friday 21 August 2026, reducing travel time by 1–2 hours with 60,000+ vehicles in the first weekend and zero accident reports. Operated toll-free Fridays–Sundays, the route aims to distribute traffic across northeast and northern regions while relieving pressure on existing Phahon Yothin and Friendship highways by 20–30%. SMEs in logistics, tourism, and regional commerce should monitor this infrastructure completion for supply chain and market access improvements.
