本州～四国桥梁工程是桥梁建设史上规模最大的。这项巨大的建设工程目前已进入高潮阶段。该工程将要修建包括世界上最长的桥梁和一些引道高架桥在内的16座大桥。从而,通过三条不同的线路来连接日本的主要岛屿本州和四国岛。为了克服环境上和技术上的种种困难,已开发了许多新的施工方法。 Honshu ~ Shikoku bridge construction is the largest in the history of bridge construction. This huge construction project has now reached its climax. The project will build 16 bridges, including the longest bridge in the world and some lead viaducts. Thus, Japan’s main islands, Honshu and Shikoku, are connected by three different routes. In order to overcome the environmental and technical difficulties, many new construction methods have been developed.
