氷の下から徐々に姿を見せ始めたタウシュベツ川橋梁の劣化が目立ちます。
The Taushubetsu bridge has appeared from under the ice covering Lake Nukabira in Hokkaido, Japan.
This bridge is scraped by ice during each winter. Therefore, the concrete deteriorates as winter passes.
橋に圧し掛かる氷は、厚さ10センチから15センチほど。全長130メートルの橋全体にかかる重さは相当のものだと考えられます。
今朝の現地では気温が氷点下20℃近くまで下がり、厳しい寒さとなりました。ただ、この寒さが緩む春先がもっとも橋の劣化が進む時期です。
Currently, the bridge is under pressure from ice 10 to 15 centimeters thick.
The length of the bridge is 130 meters. So the weight on the entire bridge is expected to be very heavy.
The Taushubetsu bridge has stood under these conditions for nearly 60 years.
糠平湖の水位は現在1日10センチから15センチほどの速さで下がり続けています。橋の全体像が見えてくるのはもう少し先になりそうです。
The Taushubetsu bridge is 11 meters high. Only the upper 1 meter or so has been seen so far.
It is expected to be a while before we will be able to view the whole structure.
