Pocheon Y-bridge

I went to the Y Bridge in Pocheon last weekend.
Art Valley, which used to be a quarry, Bidulginang Falls, and even the Y Bridge.
It was a fun trip with my friends.
The Pocheon Y-shaped suspension bridge is just the bridge itself, standing there all alone without any supporting pillars...............
And even though there weren't many people, compared to other bridges
The shaking was worse than I expected.
But I wonder what kind of technology is used to hold the weight with a Y-leg that has not a single support.
The more I look at it, the more skeptical I become.

Other suspension bridges have pillars and are connected to those pillars by wires.
Thinking that it is bearing the weight
There are no bridges in Pocheon.
