[Construction Case Study] Revive the Spectacular View: Installation Edition <First Shirakawa Bridge Restoration Project>

The removal of the old bridge and the installation of the new bridge will use the cable crane direct hanging method! We will introduce our construction examples.

The "Daiichi Shirakawa Bridge" suffered significant damage due to the Kumamoto earthquake in 2016, including displacement and deformation of the bridge structure. As a result, the damaged old bridge will be removed, and reinforcement will be carried out on the damaged parts of the substructure, followed by the construction of a new bridge. The design of the new bridge is based on the form and span arrangement of the old bridge, with the aim of making its appearance as similar to the old bridge as possible. Additionally, the removal of the old bridge and the construction of the new bridge will employ the "cable crane direct suspension method." 【Construction Overview】 ■ Project Name: Daiichi Shirakawa Bridge Restoration Work ■ Project Details: From the removal of the old bridge to the construction of the new bridge, including the reconstruction of piers and abutments ■ Bridge Type: Spandrel-braced balanced arch 　・ Bridge Length: 152.15m / Span Length: 30.44m + 90.27m + 30.44m ■ Steel Weight: Old Bridge 619.1 tons (excluding bearings) / New Bridge 635.9 tons (excluding bearings) *For more details, please refer to the PDF document or feel free to contact us.
