At Gimpo Airport the line is underground and heads north-east and rises to the surface to cross the Han River on the Magok Railway Bridge. The line descends into a tunnel and curves to the east. The line was built in a cut and cover tunnel running parallel to Susaek Station and Gajwa Station before connecting with DMC, Hongik University and Gongdeok-dong before terminating deep under ground on the west side of Seoul Station.
