Aesthetic Design of YABEGAWA Bridge

Abstract

The Yabegawa Bridge is a three-span continuous pre-stressed concrete cable-stayed bridge built across the Yabe River between the Fukuoka prefecture, Miyama city, and Yanagawa city as a center bridge. It has become the symbol of the ARIAKE ENGAN ROAD. The length of the bridge is 517m, and the center span length is 261m. Because this bridge has the plane curve, an inclined tower is adopted in order the section force that acts on a main tower has been improved. The rural scene formed by reclaiming Ariake Sea extends to the region of constructing a bridge. The Yabegawa Bridge creates new scenery in the region because of its main tower. Especially, its inclined tower doesn't see the example in another. The feature of an inclination main tower was made the best use of and a main tower was designed symbolically in landscape architecture. The details that reduced sense of oppression to the local population and natural environment were the design. It introduces these examination processes in this text.
