I am currently in Finland at the moment. I am currently in Helsinki for 1 night and I have been struck by how green this city is. There are small gardens with grass, trees, benches and paths every where sometimes just a few meters square. It’s amazing whst you can do with such small spaces and Helsinki definitely uses thst to its advantage.
Below is a picture of a tram line I saw that grass is being grown between the tracks. How amazing! Definitely a creative way to separate the road.
