# OverGrowth UnderPass (DD-441)

> Cities cover concrete walls, pillars and underpasses with climbing plants, vertical gardens and green walls. Plants such as ivy and creeping fig tolerate shade and urban conditions, and the greenery can cool surfaces, trap dust and make infrastructure more pleasant. Some cities, such as Mexico City and Chengdu, have planted overpass pillars on a large scale. The footage shows overpasses covered in plants.
