|June 2011 (38.492 Degrees, 141.290 Degrees) Tenno Bridges|
These structures (built in 1965) are both tied arch bridges with steel I girders for hangers. The hangers are flared at the top where they attach to the arch ribs. Most of the bridge was put together with high-strength bolts, but it looks like rivets were used for the arch ribs.
It seems that the Japanese make use a large variety of bridges for river crossings and they don't seem to mind the added expense of a separate superstructure for the walkway.
