M6 Motorway Opens Free Weekend Service on August 21
Thailand's Department of Highways opens a 110-kilometer stretch of the M6 motorway between Bang Pa-In and Pak Chong toll-free every weekend starting August 21, as part of a government initiative to accelerate infrastructure completion.
The Department of Highways is moving forward with the Quick-Win policy by opening a trial of the M6 motorway segment between Bang Pa-In and Pak Chong, covering 110 kilometers, for free public use every weekend beginning August 21, 2025, from noon Friday through midnight Sunday. The initiative aims to enable continuous travel from Bang Pa-In to Nakhon Ratchasima province and eventually provide round-the-clock free access to the entire route.
On August 7, 2025, Piyapong Jiwattanakul, Director-General of the Department of Highways, announced that the move follows Deputy Prime Minister Pipat Ratchakitprakarn's Quick-Win policy directive to accelerate completion of ongoing construction projects for public use. The M6 Bang Pa-In–Nakhon Ratchasima route has been prioritized for expanded trial service between Bang Pa-In and Pak Chong to ensure seamless connectivity.
The department is now ready to open the 110-kilometer Bang Pa-In–Pak Chong segment toll-free every Friday from noon through Sunday midnight, beginning August 21, 2025, and continuing weekly through the New Year 2570 holiday period. The temporary entrance and exit at kilometer 65 near the animal shelter in Nakhon Chai Buri will close, redirecting traffic to the Pak Chong toll plaza.
For travelers departing Bangkok, the M6 can be accessed from the Bang Pa-In toll plaza and driven either to the Pak Chong exit on Thanarat Road or continued through to the Nakhon Ratchasima bypass. For return trips to Bangkok, travelers from Pak Chong must use Thanarat Road and Mitra Phap Road to the Muak Lek toll plaza to re-enter the M6 toward the capital.
Active entry and exit points include Bang Pa-In, Hin Khong, Kaeng Khoi, Muak Lek, and Pak Chong toll plazas. Two rest areas operate at the Thab Kwang location (kilometer 65) on both directions, offering restrooms and beverages but no fuel or electric vehicle charging. The trial section remains under construction with speed limited to 80 kilometers per hour for four-wheeled vehicles only, and users are asked to follow all traffic signs and staff instructions.
