UPDATE: Aurora Branch closure extended through July 24th: Aurora Branch Underpass at I-88 is closed for construction.  We ask for your continued patience as the I-88 bridge work is completed and a new tunnel is put into place.  A signed detour has been provided and can be viewed in the DuPage Trails App on the “Bike Trails” tab.  The Illinois Prairie Path Not-for-Profit has published a detailed description of the detour in their February 2020 newsletter, which can be downloaded at this link.
