As of June 2015, the western half of the Calumet-Sag Trail (dubbed the Cal-Sag Trail) in the southern suburbs of Chicago is now open. The 13-mile paved pathway runs between Route 83 (Archer Avenue) in Lemont and Freedom Park (just east of Cicero Avenue) in Alsip.

Construction on the trail’s eastern segments will continue over the next two years (2015-2017). Eventually, the trail will be 26 miles and extend to Burnham. As it follows the banks of the Cal-Sag Channel and Calumet River, the trail will connect 14 communities and provide access to several forest preserves and natural areas.

The Cal-Sag Trail will connect to several other trails as well, including the largely forested Centennial Trail on its western end and the Burnham Greenway, on its eastern end close the state’s border with Indiana.
