Transportation
North Hwanghae is connected to the rest of the country (and allegedly to South Korea) by way of the Pyongbu Railway Line (known in South Korea as the Kyongui Line), which, in theory, runs from Pyongyang to Pusan; however, in reality, the line is cut short by the Korean Demilitarized Zone. It is also served by several large highways, most notably the Pyongyang-Kaesong Motorway.
