Grass is being planted on tramway lines in the capital of Bulgaria, Sofia.
In the Ruski Pametnik square, a 60-meter green ray was put into service.
City planners say the grass will reduce traffic noise, improve air quality and cool air to some extent in scorching heat.
Rain water channels were directed under the grass to meet the water requirement.
Within the scope of the greening project, grass will be planted on other tram lines in the city.
The city center is planned to close to vehicle traffic by 2020.
While many people on the social media say that the new project will give Sofia a more "European look", some argued that this was an "election investment".
