CHIANG RAI – Drivers in Chiang Rai need to prepare for big road changes this week. A major highway construction project enters its second phase soon. This work will affect travel times near the city center and the local airport. Officials urge everyone to plan their trips ahead of time.
The project focuses on the busy intersection of Highway 1 and Rural Road CR 1418. This spot serves as the main entrance to Mae Fah Luang Chiang Rai International Airport. Leaders met on September 15 to finalize the new traffic management plan. They want to keep drivers safe while road crews work in the area.
Key Takeaways
- Road changes begin soon: U-turns at the Khua Khrae intersection close on September 20, 2026.
- New traffic signals: Drivers will now use traffic lights to make U-turns in this area.
- Plan ahead: Expect traffic delays near Highway 1 and the airport entrance during construction.
Changes at Khua Khrae Intersection
Starting September 20, 2026, crews will close the current U-turn spots at the Khua Khrae intersection. This closure affects the west side heading toward Phayao and the east side. The east side is the primary route to the airport. Local officials discussed these updates at the Chiang Rai Highway District 1 office recently.
To manage the flow, the city is switching to a “U-Turn on Signal” system. Traffic lights will now direct drivers when it is safe to turn around. This new setup aims to reduce crashes and keep cars moving smoothly. Without clear signals, open U-turns often cause severe accidents on busy highways.
Safety remains the top concern for the ongoing highway construction project. Workers are installing large warning signs and bright traffic markers along the work zone. These tools will guide drivers safely through the changing road layouts. The highway department asks everyone to follow these signs closely.
Prioritizing Driver Safety
Authorities also advise drivers to slow down when approaching the airport intersection. You should listen to the traffic officers working at the site. Because lanes may narrow, you can expect some traffic jams during peak hours. Leaving early is the best way to catch your flights on time.
This construction is part of a larger plan to upgrade northern Thailand’s transport network. Once finished, the new interchange will handle heavy traffic much better. Tourists and locals will enjoy faster trips to the airport and nearby towns. Until then, patience and careful driving are your best tools.
News outlets will continue tracking the progress of this major roadwork. The highway department plans to share more updates as the project moves forward. If you drive this route daily, check for real-time traffic alerts on your phone. Staying informed helps everyone reach their destinations safely and quickly.
