Local authorities and relevant agencies have cordoned off the site and are working on measures to repair the damage.
Prolonged heavy rain on the morning of November 17 caused large cracks on the pass, disrupting traffic. The damaged downslope section stretches more than 10 metres, according to local authorities.
The pass has been temporarily closed to allow repairs and ensure safety.
