The Illinois Department of Transportation has widened IL Route 31 between Trinity Drive and James R. Rakow Road. This represents the final segment of road to be improved as part of the Algonquin Bypass Project. There is now a continuous four lane section on IL Route 31 from IL Route 176 to south of Algonquin Road. Construction was substantially completed in June of 2015. For more information, please see the IDOT's Algonquin Bypass Information page.
