Tokyo Green Space focuses largely on how green space and plants make the city livable. Recent walks through Shibuya, Meguro, and Sasazuka made me realize anew the tremendous obstacles created by elevated freeways that cut through Tokyo.
Above is the Shuto 4 expressway in Sasazuka, known as Koshu Kaido (甲州街道). There is a high speed expressway on top of an eight lane surface road. Crossing this mass of asphalt, traffic and emissions requires climbing a pedestrian overpass that goes between the levels.
Below is the 246 expressway going west from Shibuya into Meguro. If I am not mistaken, there is an elevated freeway, a surface road, and a below grade highway as well.
These massive structures are the opposite of the small lanes that make Tokyo feel so village-like and livable. There is some potential to “add” greenery to these structures. But I wonder why there isn’t more discussion in Tokyo, as there is in other world cities, about the potential for reclaiming these structures for non-automobile uses, through demolition or reuse as sky parks.
