Figures 1-4 show the Mihara Bridge newly constructed in Hokkaido, Japan. This cable-stayed bridge, open to traffic in May, 2005, has a thin composite steel/ECC deck. The tensile ductility and tight crack width control are features that contribute to a 40% reduction in weight and an expected service life of 100 years.
