Completed in 1937, it is a concrete arch bridge with a length of 130m. From around January when the dam's water is low, it reveals its appearance on the frozen lake surface, and from around May when the water level rises, it begins to sink, sinking to the lake bottom around summer. In this way, an arch bridge whose appearance appears and disappears depending on the season is only here in Japan, and that is the reason it is called the phantom bridge.

■Late spring when it becomes the Spectacles Bridge
The Taushubetsu River Bridge, from May onwards, the water level rises due to snowmelt water flowing into Lake Nukabira. Especially in the early morning, compared to daytime, because there is little wind and no waves rise, the bridge reflects on the lake surface, and because the arch appears circular as if it were spectacles, it is called "Spectacles Bridge."

■Severe winter when it reveals its appearance all alone on the snowfield
Breaking the thick ice of Lake Nukabira which begins to freeze in December, it is January when it reveals its appearance again. From around that time, you can go to see it by crossing on Lake Nukabira with snowshoes. In the blue of the winter's clear sky, and the white of the snowfield, the Taushubetsu River Bridge stands out.

■Early spring when it shows its greatly impressive appearance
Before Golden Week is the time when the Taushubetsu River Bridge reveals its entire form. The water level of Lake Nukabira is also the lowest period in the year. On the rough ground of the lake bottom, it reveals its whole image. If you gaze from the south side's shore, Mount Nipesotsu with lingering snow in the background further adds splendor.
