Interchange bridge vertical greening cases

Quick answer：

Vertical greening on interchanges refers to the practice of planting greenery on the structures of road intersections, such as flyovers and underpasses. This is done to enhance the aesthetic appeal, provide wildlife habitat, improve air quality, and mitigate urban heat island effects. Notable cases include the vertical garden on the Fondation Louis Vuitton in Paris and the green roof of the Aqualand Amusement Park in Hungary.
