Senior officials from the two Koreas are set to meet at the joint liaison office in the North Korean border town of Gaeseong to discuss inter-Korean road projects.
South Korea is sending three officials from the ministries of unification and land... and the North -- three from its environment ministry.
Seoul says the delegations will exchange road-related technical data.
It's also possible they'll discuss schedules for their joint inspections of eastern roads in the North.
Seoul and Pyeongyang checked North Korea's western expressway in August last year, but they have not checked the eastern ones yet, despite holding a groundbreaking ceremony at the end of last year.
