We went to Shikoku Island, south-west side of Japan, with our laboratory trip on October 21-22, 2018. We visited the Iya Kazura Bridge and Onaruto Bridge, well-known as the Naruto whirlpools. Next day, the graduates of the structural lab showed us the interior view of the main tower of Seto Long-span Bridge. Seto Bridge is the longest bridge for railway traffic in Japan. This trip was very memorable and full of practical knowledge of bridges. We shared the joy and spent a good time there. Looking forward to more trips!
