South Korean officials are heading north of the border on this Friday to inspect roads in North Korea.
They will be checking a 100-kilometer stretch of road on the eastern coast for three days,... and a four-kilometer section in the west next Monday.
Seoul says the inspections will be on-site visits without equipment and therefore, four days is enough time.
The inspections come ahead of a groundbreaking ceremony the two Koreas are planning to hold next Wednesday, to mark connecting and modernizing their railways and roads.
The two sides finished inspecting rail lines in North Korea earlier this month.
