Shin-Mikuni Bridge

Shin-Mikuni Bridge is a road bridge that spans the Watarase River and connects Kazo city in Saitama Prefecture with Koga city in Ibaraki Prefecture. The structure is built with steel girders and stretches approximately 2.5 kilometers across the water.

The bridge opened in 2000 as part of Japan's effort to improve transportation connections between Saitama and Ibaraki prefectures. It replaced earlier crossing methods and became a key link for regional traffic flow.

The bridge serves as a meeting point between two distinct administrative regions of Japan, each with their own local customs and traditions.

The crossing carries National Route 354 and handles vehicle traffic between the two cities throughout the day. Travel times are usually faster during off-peak hours when congestion is lighter on this main regional route.

The bridge incorporates specific engineering features of the Nielsen-Lohse design, allowing it to support heavy traffic while maintaining a streamlined structure.
