Changseon-Samcheonpo Bridge, Road bridge between Sacheon and Namhae County, South Korea.

Changseon-Samcheonpo Bridge is a 3.4 km road link between Sacheon and Namhae County made up of five bridges: Samcheonpo, Choyang, Neukdo, Changseon and Danhang. It crosses the islands of Neukdo, Choyangdo and Mogae as stepping stones, and its roadway has three lanes in total, with no central median and a yellow dashed line allowing reversible lane operation.

Construction began in February 1995 and the crossing opened on 28 April 2003, linking Sacheon and Namhae County via the islands of Neukdo, Choyangdo and Mogae. In July 2006 the Ministry of Construction and Transportation named it the grand prize winner among Korea's 100 Beautiful Roads. It gave Namhae a second land route beside Namhae Bridge, cutting travel times to Busan and Gyeongnam.

The bridge's name joins Changseon, the Namhae island it reaches, with Samcheonpo, the Sacheon district on the mainland. At the Changseon end, Namhae County runs Changseon Bridge Town, a complex with a fisheries auction hall, raw-fish restaurants, a local produce shop and a drive-in cinema; Sacheon built the Samcheonpo Bridge Memorial Park near its own approach.

The crossing carries National Routes 3 and 77 and runs three lanes with no central barrier; a yellow dashed line marks a reversible-lane system, so one direction gets two lanes and the other one. Drivers should keep to the lane indicated for their direction. At the Changseon end, the Changseon Bridge Town complex has a fish auction hall, restaurants, a raw-fish centre, a local produce shop and a drive-in cinema; Sacheon's Samcheonpo Bridge Memorial Park sits near the opposite entrance.

The crossing is not one bridge but five: Samcheonpo, Choyang, Neukdo, Changseon and Danhang bridges, using the islands of Neukdo, Choyangdo and Mogae as stepping stones. In July 2006 the Ministry of Construction and Transportation named it the grand prize winner among Korea's 100 most beautiful roads.
