Infrastructure Update: Illinois 84 closes in Jo Daviess County July 10

The Illinois Department of Transportation announced today that, weather permitting, construction on Illinois 84 in Jo Daviess County will begin on July 10. The work zone is located a mile north of Hanover and will require a road closure throughout the project.

Work will replace a culvert. A marked detour will direct traffic to use US 20, Illinois 78 and US 52/Illinois 64. The $1 million project is expected to be completed by mid-August.

Motorists can expect delays and should allow extra time for trips through this area. To avoid the work area, when feasible, use of alternate routes should be considered. Drivers are urged to pay close attention to changed conditions and signs in the work zones, obey the posted speed limits, refrain from using mobile devices and be alert for workers and equipment.

Over the next six years, IDOT is planning to improve more than 2,500 miles of highway and nearly 10 million square feet of bridge deck as part of the Rebuild Illinois capital program, which is investing $33.2 billion into all modes of transportation. Accomplishments through Year Three of Rebuild Illinois included approximately $8.6 billion of improvements statewide on 4,422 miles of highway, 412 bridges, and 621 additional safety improvements.
