This sad space could easily be improved. Neiter aesthetics nor information value seem indespensable, and planting greenery instead of advertisements which are hards read for lack of access.
This is a good idea, but I think that this supposed renewal could extend a bit further. One could easily add at least three trees and a stretch of green reaching until the next street corner.
This is a bad idea. The trees would block the view of drivers and could potentially cause accidents.
