I'm now up, but Kiyosu Bridge
The Eitai Bridge next to it is an arch bridge where you can feel the strong strength, but in contrast to it.
In addition, Kiyosu Bridge is a suspension bridge that makes you feel supple.
What is characteristic is that the other suspension bridges support the bridge girder with the main cable and hanger rope.
Both parts are steel.
The portion corresponding to the main cable is the drive chain of motorcycles and bicycles.
It looks like an extra-large version. The part that supports the bridge girder straight from this oversized chain
(It seems to be called hanger rope in general suspension bridge) is also steel.
This is the central part of the bridge
We will work until spring this year (2020), and if you look closely, there is a record of painting work.
Looking under the bridge, this is also characteristic and there are eight large dampers, rather than earthquake resistance.
It improves seismic isolation or vibration isolation and prepares for earthquakes.
Tsukuda-ohashi Bridge is also equipped with a damper to prepare for an earthquake, but the size and number are different.
earthquake countermeasure seems to be different depending on the structure of the bridge, and it is interesting to look under the bridge.
