The Illinois Tollway has agreed to contribute $2 million toward the restoration of a more than half-mile section of creek running through the St. James Farm Forest Preserve.
The preserve located west of Chicago in Warrenville is home to more than 100 acres of woodlands, prairies and wetlands.
The restoration project will reconfigure a section of Spring Brook Creek to replicate a more natural, meandering stream. Workers will also remove non-native and invasive plants.
The creek was originally excavated as a drainage ditch in the early 1900s. It flows southwest from Wheaton to the west branch of the DuPage River.
The Tollway is sponsoring the work as part of a deal with DuPage County to mitigate impacts associated with construction of the Elgin O'Hare Western Access Project.
