Kachidoki Bridge

A bridge spanning Tsukiji and Kachidoki in Chuo City, Tokyo on the lower reaches of the Sumida River. The bridge was completed in 1940 and was to serve as the main gate for a world's fair scheduled to be held in Tokyo (which was ultimately suspended due to the war). Kachidoki bridge is a movable bridge able to open up in the middle, and when first built it was the largest of its kind in Asia. As fewer and fewer large boats traveled the Sumida River, however, it became unnecessary to raise the bridge-the last time it was opened was in 1970.
