From source of pollution the green lung of the city. The municipality of Paris has carefully examined the situation of the so-called boulevard périphérique, the ring road that has served as the tangential around the French capital, to reach a 'green' solution. In a document, strongly supported by the mayor Anne Hidalgo, it is proposed to impose a speed limit of 50 kilometers per hour by 2024, and then move to a almost total pedestrianization by 2030. An average of 1,2 million vehicles pass through the Paris ring road every day, and being a fast-flowing road that cuts through the heart of the city, it is a source of significant noise and air pollution.
PARIS RING ROAD PEDESTRIAN ZONE
The undeclared but clear aim is to transform the artery into a urban park, a bit like the famous “High Line” in New York, where citizens can reclaim a strip of land that for decades was the exclusive prerogative of carsTo make possible what currently seems like a utopia, it is necessary toimplementation of public transport or of green mobility that can make up for the elimination of one of the main arteries of Parisian traffic.
URBAN PARK RING ROAD
In the document, the experts consulted by the municipality have identified 40 measures to transform this ring road first into an "urban boulevard," where vehicles will travel at no more than 50 kilometers per hour, and then into an almost entirely pedestrian zone. During this transformation, urban planners and architects propose returning the unused lanes to residents through competitions that reward the creative use of the road.

THE HIGH LINE IN NEW YORK
This type of solution has been put into practice, albeit in a more complete manner, in New York, where a disused section of the elevated railway called West Side Line it was transformed into a linear park. 2,33 kilometers long, theHighline' runs along the western side of Manhattan and has become a favorite spot for New Yorkers and tourists.

Demolition of the Eastern Ring Road in Rome
A similar project has also been promoted in Rome, where Virginia Raggi's government has allocated 9,9 million euros in the budget adjustment for demolish the 460-meter stretch of the Eastern Ring Road in front of Tiburtina station. In its place, civic committees and associations dream, here too, of a linear park and green walks but, for the moment, jobs which were due to start by the summer they are still stuck and it is not known when they will be able to start.
