The Department of Highways closes the M82 motorway (25 km, Bangkhunthian–Banpaew) in August 2026, then launches Phase 1 of an elevated parallel extension on Bromratchachonnani Road (4.63 km, ฿4.39 billion) from October. Full Bromratchachonnani expansion (~22 km total, additional ฿12.25 billion) will connect to future M8 (Nakhonpathom–Pakhtho–Chachoengsao, 61 km, ฿54.6 billion) and M81 motorways. Bangkok also plans a ฿3.5 billion elevated connector from Rama 8 Bridge. These infrastructure projects aim to ease west-side congestion and unlock premium land values in the western zone.
