They are removing other overpasses because they are eyesores, but...

Instead, they are preserving the area in front of Seoul Station and transforming it into an elevated pedestrian walkway. Wow.
Is this the right way to go??
In other areas, they are demolishing overpasses and building underground instead. Wow.
It's not a neighborhood I live in, but if the old downtown areas of Seoul like this one undergo railway undergrounding, they really won't be envious of Gangnam..
