Elevated park

This type of a park has become more popular in the early 21st century, featuring in a number of urban renewal projects.

[5][9][10] One of the earliest of such parks was the Promenade plantée (Coulée verte René-Dumont) in Paris, dating to 1993.

[11] It has proven popular enough to encourage other cities to consider similar projects, a process that gained further momentum after the success of the High Line, the first such park in the United States, which opened in 2009.

[17][15] Elevated parks have been criticized for high costs, though they have generally attracted positive reviews, including from academia.

[17] In 2016, a public referendum to convert Seattle's Alaskan Way Viaduct into an elevated park, inspired by the High Line, was strongly rejected by voters.

The High Line in New York City is built on a disused elevated railway.
Seoul 7017 Skypark is a new park converted from a defunct overpass.
