As part of a plan to bring more open space to Chicago’s northwest side, the city converted the underused Bloomingdale Rail embankment into a 2.7-mile elevated trail linking a series of grade-level parks.

When active rail service ceased in the 1990s the embankment was reclaimed by community members as an impromptu trail. In the early 2000s the idea gained traction through several community-based visions and in 2004 as part of the Logan Square Open Space Plan. The linear park had widespread community support and input from the beginning, helping to develop the park’s design, function, and aesthetics. The 606—named for Chicago’s zip code prefix—opened in 2015, connecting four diverse neighborhoods, and bringing together arts, history, and design. The park and trail system includes the elevated Bloomingdale Trail for bikers, runners, and walkers, which connects four existing and 2 planned access parks at the ground level; alternative transportation avenues; and green, open space for Chicago. The 606 network is a public-private partnership between the City of Chicago, the Chicago Park District, the Trust for Public Land and Friends of the Bloomingdale Trail.

Urban parks, vacant lots could become '30x30' targets

Stretching nearly 3 miles along a former elevated train track in Chicago, the Bloomingdale Trail draws pedestrians and cyclists down its paved path — the centerpiece of a park system often cited as a model urban green space that integrates access, recreation and transportation.
