We're at the halfway point of the 10-day long Chuseok holiday.
More and more Koreans are hitting the road and heading back home.
It's going to be a longer ride than usual for travellers moving both in or out of the capital.
As of 5pm local time, those driving to Seoul from Mokpo should brace themselves for a 6 hours and 10 minute journey, 6-40 from Busan, 5-20 from Gwangju, and slightly longer than 3 hours from Daejeon.
According to the Korea Expressway Corporation over 5 million vehicles are expected to pack the roads today alone.
Traffic heading to the capital is expected to peak at around this hour, before returning to normal levels at around dawn on Friday.
For travelers moving in the opposite direction, congestion should ease after 7 pm.
