A long coastal span that turns raw civil engineering into a clean, repeatable rhythm.
Road bridge between Dangjin-si, Chungcheongnam-do and Pyeongtaek-si, Gyeonggi-do, South Korea.
Visitor Guide
Find a shoreline viewpoint rather than stopping on the roadway—watch how the span cadence changes as it meets land.
From a coastal park lookout at sunset, facing the bridge with the sun raking the pylons (exact park varies—use local mapping to find a clear sightline).
Drive across; viewpoints from shore are best. No interior or tours.
On big sea crossings, the ‘architecture’ is in the joints: expansion devices, bearings, corrosion protection—unsexy details that determine lifespan.

Design & Structure
Span configuration selected via cost/wind/navigation constraints; final geometry tuned through FEM and durability engineering for a marine environment.
Concrete/steel with aggressive corrosion protection strategies suited for salt air.
Wind stability and fatigue govern cable and deck detailing over water.
