CDOT is also planning to add bike lanes to the two-lane stretch of 103rd Street from Michigan Avenue west to Vincennes at a yet-to-be-determined date.



       Big Marsh was built on a former steel mill slag-dumping site. The roughly 44-acre bike park opened this year on the most heavily polluted portion of the property, and environmental remediation is still under way on the remaining 234 acres, a patchwork of open water, marshes, prairie, and woodland.



       “We’re very heartened to hear the plans by CDOT to improve conditions for biking on surrounding streets,” says Active Trans advocacy director Jim Merrell. “Ensuring local communities don’t have to rely on driving to access Big Marsh and other new parks is a big priority for us.”



       “Any work we do around Big Marsh will first prioritize equity and community ownership of the planning process,” Black says, “as well as a healthy respect for the communities, culture, and history that have made Big Marsh the treasure it is today.”
