From Friday 21 Aug 2026, noon to midnight Sunday, every week until New Year, the M6 Bangkok Expressway section Bang Pa-in to Pak Chong is free for cars. Trucks are not allowed, and speed is capped at 80 km/h. Northbound you can join at Bang Pa-in; the Pak Chong temporary access at km 65 closes, so use Pak Chong toll. Coming back to Bangkok, use Thanarat and Mittraphap Road to Muak Lek. No fuel stations on the section, but there is a rest stop at Thap Kwang with toilets and drinks. Plan delivery routes and staff travel around this, since trucks are excluded.
