Andodaegyo Bridge
Andodaegyo Bridge is part of Dadohaehaesang National Park.
The bridge connects Geumodo Island and Ando Island. It was built to improve transportation between the islands, make daily life more convenient for local residents,
and provide easier access for tourists visiting the Geumoyeoldo (Geumo Archipelago), which is part of Dadohaehaesang National Park.
Ando Island was originally called Anho, using the Chinese character an, meaning “wild goose,” because the island’s shape resembles a goose. Today, it is called Ando, using a different Chinese character an, meaning “peace.” Viewed from above, Ando Village resembles the shape of the Korean Peninsula.
Ando Island is also a popular fishing destination, with numerous fishing spots and a wide variety of fish species found throughout its waters. Anglers can enjoy catching fish such as sea bream, rockfish, and Korean rockfish.
Andodaegyo Bridge connects Simjang-ri on Geumodo Island and Ando-ri on Ando Island, both in Nam-myeon, Yeosu. The bridge measures 360 m in length and 12.5 m in width. Construction began in 2005, and the bridge opened in February 2010 after five years of work. The bridge connecting Geumodo Island and Ando Island is a hybrid extradosed bridge featuring a 200 m main span, the longest of its kind in Korea. Its main towers stand 46.2 m tall, while the bridge deck is positioned 27.1 m above sea level to ensure the safe passage of ships.
A total of 36 stay cables connect the main towers to the bridge deck. Each cable consists of 37 steel strands, each measuring 12.5 mm in diameter, and is protected against corrosion with a high-density polyethylene coating. The concrete bridge deck was constructed using the Free Cantilever Method (FCM), in which concrete is poured in successive sections extending symmetrically outward from both sides of the main towers using form travelers, a movable formwork support system. A distinctive feature of Andodaegyo Bridge is its relatively low main towers, which depart from the conventional design of towering bridge pylons. This design preserves views of the surrounding islands and seascape.
