One of the parks opened last month in Logan Square. The city has begun seeking proposals for preliminary design work, including studying the sturdiness of the embankment and 37 viaducts that support the raised railroad corridor from Ridgeway Avenue to Walsh Park.
Officials are hoping the project—the Bloomingdale Trail—could be completed within seven years. But first they face a daunting task: finding at least $45 million in government funding.

Officials say the Bloomingdale Trail would be the longest elevated trail in the country, spanning nearly 3 miles.
Cyclists would be 18 feet above traffic, at eye level with second-story homes but just below CTA trains rattling by on the Blue Line. Railing or landscaping could be used to prevent them from veering off the trail.

Supporters hope they could eventually connect the trail, which would end at Ashland Avenue, to the Chicago River and lakefront trails to the east. The trail meets..."
