Nagaoka Bridge

The Nagaoka-ohashi is a road bridge spanning about 1 kilometer across the Shinano River and connecting different areas of the city via National Route 8. The structure uses steel girder systems to support the long distance across the water.

Construction was completed in November 1970 and represented an important step in Japan's infrastructure development following the post-war period. The completion helped better connect the previously fragmented city.

The bridge serves as a daily crossing point where locals walk and travel, becoming a familiar landmark in the rhythm of city life. It forms part of the urban landscape that residents navigate without thinking much about it.

The bridge is accessible both by foot and by car and provides a clear crossing for both types of traffic over the river. Visitors should be aware that it can be heavily used during peak traffic hours.

The structure was specifically designed to withstand the heavy snowfall and harsh winters typical of this region. The robust construction shows how infrastructure was adapted to Japan's natural conditions.
