Short Description of Work

DuPage County is improving the intersection of Powis Road and North Avenue (Illinois Route 64) by widening Powis Road to allow two southbound through-lanes on and double left turn lanes from both northbound and southbound directions; re-striping for double left turn lanes from westbound North Avenue and a right turn lane from eastbound North Avenue; improving stormwater drainage facilities; and installing the permanent traffic signal at the intersection.  These improvements were part of the plans when North Avenue was reconstructed and widened in 2013, but this portion of the project was deferred.

Traffic Control

This project will be constructed in several stages.  Along Powis Road, a left turn lane and through lane will be open in each direction at all times.  Daytime lane closures along North Avenue will be required at times.
