The Highways Department opens the 25 km M82 motorway (Bang Khun Thian–Ekachai–Ban Phaeo) on 28 August 2026. From October it starts the elevated extension of Borommarat Chonnani Road (Phutthamonthon Sai 3–Sai 4, 4.63 km, 4.386 billion baht, due 2029), with traffic closed in phases. Road traffic on Borommarat Chonnani is about 265,982 vehicles a day. If your business is on or near this corridor, expect congestion and plan delivery routes via the alternatives (Phran Nok new road, Phutthamonthon Sai 4, Rama 2). The longer-term Pechkasem section (12.25 billion baht) is still under review, so it does not affect decisions this year.
