Tone River Bridge

Tone River Bridge is a reinforced concrete structure crossing the Tone River in Chiba Prefecture as part of the Higashi-Kanto Expressway system. It allows traffic to pass over this major waterway while maintaining the continuous flow of the expressway through eastern Japan.

The bridge was built during the 1960s as part of Japan's infrastructure expansion program to improve transportation connections. It was constructed to support rapid development in eastern regions and link them more efficiently to Tokyo.

The structure stands over the Tone River, which functions as a vital water source for agriculture and transportation in the Kanto region

Access to this crossing is only possible via the Higashi-Kanto Expressway, with toll stations at each end of the bridge. Visitors should note that this is a toll road and all vehicles must comply with expressway regulations.

This crossing spans Japan's second-longest river, which carries more water than any other river in the country. The Tone River is a critical water source for extensive areas of the Kanto region, making this bridge strategically important.
