We would like to introduce the "Fukuoka No. 208 Chikugogawa Bridge Superstructure (P4-P8) Construction." The Chikugogawa Bridge is a long bridge spanning the Chikugo River with a length of 450 meters and a maximum span of 170 meters, featuring two arches. Its horizontal design and gentle arch curves create a lightness as it gracefully crosses the river, harmonizing with the spacious surrounding landscape. Additionally, it is constructed as a "steel arch bridge," allowing for lower pier heights on the de Reike embankment, thereby reducing the sense of pressure. The construction method involves a crane erection method that uses temporary support materials called bent to connect the bridge girders. For the erection between P5 and P6, a special jack is used to gradually advance the bridge girder forward, employing a launching erection method. 【Bridge Specifications】 ■ Bridge Type: Steel 4-span continuous (2-span) single-arch bridge ■ Bridge Length: 450m ■ Arch Spans: 170m, 153m ■ Arch Rise: 30m, 27m ■ Width: 20.5-21.4m ■ Total Weight: 6465t *For more details, please refer to the PDF document or feel free to contact us.
