IDOT - Rte 21 & 137 Project
Businesses along the construction route remain open during construction. Please don't forget to patronize these businesses. 

As the contractor works to complete the project, we would like to remind motorists to observe all construction barricades and signage. 

For cyclists and pedestrians: please stay out of the designated construction areas. As always, everyone’s safety is top priority.

Construction Advisory
On Monday, April 21st, traffic on NB and SB IL 21 will be placed in the outside lane (lane 2) from Janas Court to the north project limit.  This will enable Walsh/sub-contractors to complete remaining work including median landscaping, crossover restoration, curb & gutter placement, and various punch list items.
