Raiden Todoroki Bridge, Spiral bridge in Chichibu, Japan.
The Raiden Todoroki Bridge features a double crossing configuration with two beam bridges crisscrossing the Nakatsu River at a height of 325 feet.
Completed in 1998, this engineering structure received the Japan Society of Civil Engineers Tanaka Prize and Good Design Award for its architectural excellence.
The bridge represents modern Japanese engineering principles through its structural design, connecting the upper edge of the river valley to the bottom.
