An amphibious bus sails on the Seoul-Incheon Canal in the port city of Incheon, west of Seoul, on April 21, 2015, as the operator of the bus, the first of its kind in South Korea, implemented a test run. The canal, dubbed the "Ara Waterway," connects the Han River, flowing through central Seoul, and the Yellow Sea, enabling seagoing ships to enter Seoul. (Yonhap) (END)
