In New York City, there is a park that sits on a freight rail line elevated above the streets on Manhattan’s West Side. It is called the High Line. It was opened in 1999 following the example set by the Promenade plantée an elevated linear park built on top of obsolete railway infrastructure in Paris, France, inaugurated in 1993.
What these two impressive parks have inspired in London could be really amazing. Thomas Heatherwick wants to build the Garden Bridge, a pedestrian pathway across the Thames landscaped as a park. I love the idea. I'm wondering about the feasibility of doing something like that here at the mouth of the Cuyahoga River.
