PLEASE NOTE: This fall, the City of St. Charles will be doing water and sewer main work, impacting the intersection just south of the Kane County Extension office and closing northbound traffic on Randall Road. The project is expected to begin this week and continue through November. There will be posted detours for those coming from U.S. Route 38 north. Please plan your travel time and route accordingly.
