The Bloomingdale Trail is a 2.7-mile (4.3 km) elevated rail trail linear park running east–west on the northwest side of Chicago. It is the longest greenway project of a former elevated rail line in the Western Hemisphere, and the second longest in the world, after the Promenade plantee linear park in Paris. In 2015, the City of Chicago converted the former Bloomingdale railway line to an elevated greenway, which forms the backbone of the 606 trail network. The Bloomingdale Trail elevated park is in the Logan Square, Humboldt Park, and West Town community areas.

The Coulée verte René-Dumont or Promenade plantée René-Dumont is a 4.7 km (2.9 mi) elevated linear park built on top of obsolete railway infrastructure in the 12th arrondissement of Paris, France. It was inaugurated in 1993.
