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.

Logan Square is an official community area, historical neighborhood, and public square on the northwest side of the City of Chicago. The Logan Square community area is one of the 77 city-designated community areas established for planning purposes. The Logan Square neighborhood, located within the Logan Square community area, is centered on the public square that serves as its namesake, located at the three-way intersection of Milwaukee Avenue, Logan Boulevard and Kedzie Boulevard.
