Thailand's Department of Highways Updates Access Rules at Two M6 Toll Plazas

Key summary

Starting noon on November 2, 2026, Thailand's Department of Highways will implement new entry and exit procedures at the Sikhio and Kham Thale So toll plazas on the Bang Pa-in–Nakhon Ratchasima motorway (M6). These changes follow the completion of construction work on the 196-kilometre route, which has faced repeated delays from its original 2020 completion target due to engineering revisions, contract changes, and site condition differences identified in 2018 documents. At Sikhio, the access point shifts from kilometre 5+500 to kilometre 6+000 on Highway 201. At Kham Thale So, vehicles can now proceed straight onto the main carriageway instead of using a side diversion. Drivers must use the two right-hand M-Flow lanes at both plazas and adhere to warning signs, signals, and officer instructions. The route serves as an alternative between Bangkok and northeastern Thailand, easing pressure on existing roads during holidays. While sections like Pak Chong–Nakhon Ratchasima are open for toll-free trial use daily, and the Bang Pa-in–Pak Chong section operates on weekends, this announcement specifically addresses access improvements and does not signal the start of full commercial toll collection or complete route operation.
