出羽大橋

Dewa Great Bridge is a four-lane bridge spanning 861.3 meters across the Mogami River in Sakata. The newer span carries southbound traffic on two lanes and includes a 4.5-meter-wide pedestrian walkway with wooden benches for resting.

The original two-lane bridge opened in 1972, while expansion to four lanes was completed in 2008 with the construction of a parallel structure. This growth reflected increasing traffic demands across this important river crossing.

The railings display relief designs of the Mogami River, and visitors gather at observation balconies to watch migrating swans pass through. This setup creates natural gathering spots where the river's seasonal rhythms become part of the visitor experience.

Crossing on foot is easy with benches along the pedestrian path for breaks. Early morning or late afternoon visits work best for observing wildlife and enjoying the light across the river.

Over 11,000 swans gather in the adjacent Swan Park during winter months, making this location Japan's largest swan congregation. This remarkable seasonal assembly transforms the bridge area into the region's prime spot for witnessing this natural gathering.
