Yi Sun-sin Bridge, Suspension bridge in Yeosu and Gwangyang, South Korea
This suspension bridge extends 7,415 feet (2,260 meters) across the South Sea, featuring a main span of 5,069 feet (1,545 meters) and towers reaching 896 feet (273 meters) in height.
Construction began in November 2007 and the bridge officially opened to traffic on May 12, 2012, just in time for the international Expo exhibition held in Yeosu that same year.
The bridge honors Admiral Yi Sun-sin, a celebrated Korean naval commander from the Joseon Dynasty who invented the ironclad turtle ship and successfully defended Korea against Japanese naval invasions in the 16th century.
The toll-free bridge provides four vehicle lanes across its 89-foot (27-meter) width and includes dedicated bicycle paths, connecting Gwangyang with Yeosu and reducing travel time between the two cities significantly.
The bridge towers were completed in just 11 months, a remarkably fast construction timeline compared to similar structures like Denmark's Great Belt Bridge, whose towers took 30 months to build despite being shorter.

This collection gathers bridges that hold world records for span length, defined as the distance between two main pylons. While the longest bridge in the world measures 165 kilometers in China, this refers to the maximum span covered in one continuous structure. These constructions demonstrate engineering achievements in crossing maritime straits, rivers, or valleys without intermediate supports. The Çanakkale Bridge in Turkey crosses the Dardanelles Strait with a span of 2,023 meters, setting the current record for suspension bridges. In Japan, the Akashi Strait Bridge connects Kobe to Awaji Island with a central span of 1,991 meters. In China, several bridges exceed 1,600 meters in span, such as the Yangsigang Bridge over the Yangtze in Wuhan or the Xihoumen Bridge in the Zhoushan Archipelago. South Korea with the Yi Sun-sin Bridge, Denmark with the Great Belt Bridge, and Turkey with the Osman Gazi Bridge complete this list of remarkable structures. These bridges are interesting destinations for observing modern civil engineering accomplishments. They connect cities and regions, significantly reducing travel times while offering scenic views of the landscapes they cross. Visiting them allows appreciation of the scope of work involved in constructing these infrastructures under often challenging conditions.
