South Korea highways choked on Labour Day as 6 million vehicles hit roads
Synopsis
Key Takeaways
Highways across South Korea were heavily congested on Friday, 1 May 2025, as outbound traffic surged on the first day of an extended public holiday that began with Labour Day. More than 6 million vehicles were estimated to travel nationwide, with drive times from Seoul stretching to record highs, according to the state-run Korea Expressway Corp, as reported by Yonhap News Agency.
Road Congestion at Peak Levels
A drive from Seoul to the southeastern port city of Busan was expected to take up to 9 hours and 10 minutes at peak times — one of the longest estimated journey durations on that corridor in recent memory. A trip to the southwestern city of Gwangju was projected at 7 hours and 30 minutes, while the eastern coastal city of Gangneung was estimated at 6 hours and 20 minutes. The Korea Expressway Corp expected outbound traffic to ease from around 9 to 10 pm and inbound traffic returning to Seoul to ease from 10 to 11 pm.

The holiday rush extended beyond the roads. An estimated 1.3 million people were expected to take flights departing from or arriving at Incheon International Airport, west of Seoul, from the previous day through Tuesday, according to industry data. The spike reflects a broader rise in demand for international travel during extended holiday windows — a trend that has accelerated in the post-pandemic period as South Korean consumers prioritise leisure spending.
Why the Holiday Is Longer This Year

The South Korean government earlier this year designated Labour Day as a full national holiday, allowing all workers — not just unionised employees — to take the day off. With Children's Day, another national holiday, falling on Tuesday, 6 May, workers who take Monday off can enjoy up to five consecutive days of rest including the weekend. South Korea had originally observed Labour Day on 1 May before renaming it
