That doesn’t just mean to make the boulevard more environmentally friendly. “Anne Hidalgo said the planned work, unveiled in 2019 by local community leaders and businesses, would turn the 1.9 km (1.2 mile) stretch of central Paris into ‘an extraordinary garden’. … The eight-lane highway is used by an average of 3,000 vehicles an hour, most passing through, and is more polluted than the busy périphérique ring road around the French capital.” – The Guardian
