Yaro Bridge opened in 2016 as the highest bridge in South Korea and the first high level extradosed bridge in the country.
The Japanese built their first extradosed bridge in 1993 and now have more than 100 examples - more than every other country in the world combined. Yaro Bridge in one of the few to be built in South Korea.
Extradosed bridges are a cross between a concrete beam bridge and a cable stayed bridge. Unlike a cable stayed bridge where the stays are spaced evenly across the entire deck from tower to tower, the center third of an extradosed bridge is usually devoid of cables as is the immediate area on either side of the main towers where there is always an open “window”.
By relying much more on the strength of the thicker, prestressed concrete beam span below the roadway, extradosed bridges can have much shorter towers with fewer cables. Extradosed bridges are not suitable for long spans and they have been built primarily as a prettier alternative to the dull look of a pure beam bridge.
