Construction alerts are projects that have already been designed and planned and now are under construction. The projects listed on this page are updated on a more frequent basis, as the construction phasing changes and new information is made available. Any questions or comments should be directed to the Department of Transportation, Engineering and Development at (630) 420-6100.
