Toll Fee Increase Announced for Si Rat-Outer Ring Road Expressway
The Thai Ministry of Transport has officially announced a toll hike for the Prachim Ratthaya Expressway, effective December 15, 2026.
According to a report by Khaosod Online Thailand, the Royal Thai Government Gazette has published a new Ministry of Transport announcement regarding toll rates for the Prachim Ratthaya Expressway, commonly known as the Si Rat-Outer Ring Road Expressway. This adjustment follows a decision made by the Expressway Authority of Thailand (EXAT) board during their meeting on July 14, 2026, in accordance with the existing investment and management concession contract.
The new toll structure is set to take effect on December 15, 2026. For residents and frequent commuters in Bangkok, this change represents an increase in daily travel costs when utilizing this specific route. Travelers planning to use the expressway after the mid-December implementation date should prepare for the updated pricing.
While the official announcement confirms the implementation date and the legal basis for the adjustment under the Expressway Authority of Thailand Act of 2007, specific details regarding the exact new price tiers for different vehicle categories were not fully detailed in the initial report. Commuters are advised to monitor official EXAT channels or future government gazette updates to confirm the precise toll rates applicable to their specific vehicle type before the December deadline.
