Cheonsa Bridge

Cheonsa Bridge stretches 650 meters across open water and links islands in the Sinan archipelago using both suspension and cable-stayed techniques. The crossing rises up to 85 meters above sea level to allow ships safe passage beneath its span.

Construction started in 2010 following years of planning and continued for nine years until completion. Traffic began flowing on April 4, 2019, establishing a direct road link between previously isolated islands.

The name derives from the Korean word for angel and refers to nine islands forming a diamond pattern when viewed from above. Local residents regard this link as a symbol connecting communities that relied solely on ferries before the crossing opened.

Traffic is restricted to motor vehicles only, with pedestrians and cyclists barred from crossing. The roadway consists of two lanes allowing steady speed without signals or intersections along the entire length.

The structure marks the first time South Korea combined two different bridge designs within a single crossing. This technical solution addressed varying water depth and seabed conditions along the route.
