TOKYO — Officials Wednesday formally marked the completion of the final span of the world's longest double-decker bridge, which links Japan's main island of Honshu and its smallest island of Shikoku.
The 5.8-mile suspension bridge will be opened to traffic next spring after the paved roadway and railroad tracks across the span are completed. Wednesday's ceremonies marked completion of a 5,653-foot segment of the bridge, the longest and final section.
