Before Dolsan Bridge was built, Dolsando Island could only be reached by boat. That changed completely on December 15, 1984, when a 450-meter-long, 11.7-meter-wide, 62-meter-high cable-stayed bridge was completed, connecting Nam-san-dong on the Yeosu mainland with Udu-ri in Dolsan-eup. Island residents no longer had to plan their lives around ferry schedules, and Dolsando was effectively absorbed into Yeosu's extended living area.
Dolsan Bridge came to represent more than just practical function — it also became a symbol of Yeosu's night skyline. When evening falls, the bridge lights up, forming one part of the nightscape known as "Yeosu Night Sea." Today, most visitors heading toward Dolsando's attractions — Hyangiram, Dolsan Park, or the cable car terminal — cross this very bridge. A bridge that once absorbed an island into a city now also functions as one of the lights that completes that city's nighttime scenery.
