The City of Naperville and its partners hosted a ribbon cutting ceremony to celebrate the completion of Segment 4 of the DuPage River Trail. The 2.5-mile extension of the regional trail begins near 87th Street and the West Branch DuPage River and continues south, along Ring and Knoch Knolls Roads, through Knoch Knolls Park, and ending at the DuPage River Sports Complex. The path includes two pedestrian bridges: one over a creek south of 87th Street and one over the West Branch DuPage River in Knoch Knolls Park (see the map below). Naperville received federal funding for this construction project through the American Recovery and Reinvestment Act (ARRA) and the Congestion Mitigation and Air Quality Improvement Program (CMAQ).

In addition, Section 2 of the trail (from Hobson Road to Bunting Lane) is now open. As part of the project, two new underpasses have been built to allow pedestrians and bicyclists to pass beneath both 75th Street and Washington Street. This project also received CMAQ funding. A ceremonial ribbon cutting for the project (75th and Washington intersection reconstruction) will take place on Monday, October 4, 2010.
