Emergency restoration works after
the Kumamoto Earthquake (Kiyama Bridge)

On April 14, 2016, a significant earthquake struck near the epicenter in Kumamoto, causing extensive damage to the Kiyamagawabashi Bridge on the Kyushu Expressway between the Mashiki Kumamoto Airport IC and the Matsuhashi IC. Because the damaged Kyushu Expressway was an important arterial road, the lower part of Kiyamagawabashi Bridge was supported with BH piles  (780m road, 300 bearing piles), and vehicles were allowed to drive with the speed limit of 50km/h during May. 

The construction was held with total of 90 people by assembling 10 sets of equipment and 17 construction team from all over Japan during consecutive holidays. It was successfully to complete the construction by the target month which is May. Subsequently, temporary support vents were installed, and the main restoration work was carried out, leading to the full restoration of the four-lane road between the Mashiki Kumamoto Airport IC and the Matsuhashi IC by 28th April 2017.
