As Korea's Chuseok holiday period runs through Wednesday,... millions of people are making their way back to Seoul.
Slow-moving lines of vehicles have formed on most of the country's expressways,.. after Seoulites celebrated Chuseok with their families in their hometowns or went for a short vacation.
According to the Korea Expressway Corporation, some five million vehicles are expected to be moving across Korea on Tuesday alone.
Traffic jams are likely to continue throughout the evening and into the early hours of Wednesday morning.
