M6 Motorway opens Bang Pa-in–Pak Chong section free at weekends
The M6 motorway between Bang Pa-in and Pak Chong will open toll-free at weekends from August 21, with five entry and exit points available.
The Department of Highways will open the Bang Pa-in–Pak Chong section of Motorway M6 for toll-free trial use at weekends, beginning at noon on Friday, August 21, 2026.
The new section of the Bang Pa-in–Nakhon Ratchasima motorway will be available from noon on Fridays until midnight on Sundays.
The trial service is intended to ease heavy traffic on Mittraphap Road and improve journeys between Bangkok and northeastern Thailand, particularly for people travelling home or visiting tourist destinations.
Five M6 entry and exit points available
Motorists will be able to enter or leave the Bang Pa-in–Pak Chong section at five locations:
- Bang Pa-in interchange: The starting point for motorists travelling from Bangkok and Pathum Thani
- Hin Kong interchange: Connecting to Nong Khae district in Saraburi
- Kaeng Khoi interchange: Providing access to industrial areas and Kaeng Khoi district
- Muak Lek interchange: Serving travellers heading towards Muak Lek and the Khao Yai area
- Pak Chong interchange: The end of the trial section and the connection to the Pak Chong–Nakhon Ratchasima section
The Wang Noi and Saraburi interchanges will remain closed while preparations continue. Motorists are advised not to turn into these access points and to follow road signs carefully.
Pak Chong–Nakhon Ratchasima section remains open around the clock
The Pak Chong–Nakhon Ratchasima section of M6 will continue operating toll-free every day, 24 hours a day.
The section supports motorists travelling to Nakhon Ratchasima and other provinces in the Northeast and remains open for both inbound and outbound journeys.
At noon on August 21, the access point near the stray-animal shelter will be closed. Motorists using the route are advised to adjust their travel plans in advance.
Three safety rules for M6 users
Although the motorway is free to use during the trial period, strict safety requirements will remain in force.
- Only four-wheeled vehicles will be permitted on the route.
- The speed limit will be 80 kilometres per hour because the section remains under trial operation and road-surface improvements are continuing at some locations.
- Drivers must follow all warning signs and instructions from officials.
For real-time route information or assistance during a journey, motorists can contact the Department of Highways call centre on 1586, available 24 hours a day.
