Chiang Rai Implements New U-Turn Rules from Sept 20, Affecting Airport Access

CHIANG RAI – Drivers in Chiang Rai are advised to prepare for significant traffic adjustments beginning September 20, as a major highway construction project enters a new phase. The changes will impact travel times, particularly near the city center and the Mae Fah Luang Chiang Rai International Airport. The project focuses on the crucial intersection of Highway 1 and Rural Road CR 1418, a primary gateway to the airport. Officials finalized a new traffic management plan on September 15 to enhance safety during roadwork. Effective September 20, 2026, U-turn facilities at the Khua Khrae intersection will be closed. This closure affects both the west side, leading towards Phayao, and the east side, the main route to the airport. Local authorities discussed these updates at the Chiang Rai Highway District 1 office. A "U-Turn on Signal" system will replace the existing U-turns. Traffic lights will now dictate when drivers can safely perform a U-turn, aiming to reduce accidents often caused by uncontrolled turns on busy highways and to maintain smoother traffic flow. Safety is paramount, with the installation of large warning signs and bright traffic markers to guide drivers through the evolving road layouts. The highway department urges strict adherence to these signs. Authorities also recommend drivers slow down near the airport intersection and heed instructions from traffic officers. Narrowed lanes may lead to traffic jams during peak hours, and early departure is advised for those traveling to the airport. This construction is part of a broader initiative to upgrade northern Thailand's transportation network, promising improved traffic handling and faster journeys to the airport and surrounding towns upon completion. Patience and careful driving are essential during this period. News outlets will monitor the project's progress, with the highway department planning further updates. Real-time traffic alerts are recommended for daily commuters on this route.
