We take care to keep the appearance as close to the original as possible! With our technology, we will restore that breathtaking view.
The "First Shirakawa Bridge" suffered numerous deformations and fractures in its supporting components due to the Kumamoto earthquake in 2016, resulting in a decrease in strength. To restore this railway line and once again enjoy the beautiful scenery, it became necessary to construct a new bridge. This beautiful bridge, which has a rich history, will be carefully designed to maintain its appearance as much as possible while being transformed into a safe and secure structure using new technology. MMB is committed to delivering that breathtaking view back to many hearts and is cooperating on the bridge replacement project with the aim of a swift restoration. 【Main Design Loads】 ■ Train Load: EA-15 ■ Design Speed: 70 km/h ■ Earthquake Load: L1 seismic motion, L2 seismic motion ■ Dam Water Level: During water retention tests and design flood conditions (considering water pressure and buoyancy) *For more details, please refer to the PDF document or feel free to contact us.
