The Illinois Department of Transportation plans to reduce Illinois 161 to one lane at the Silver Creek Overflow during daylight hours starting on Tuesday, weather permitting, the agency said.
Intermittent daylight lane closures will be in place until temporary traffic signals are installed at the work location, which is 1.8 miles east of Illinois 158, IDOT said.
The temporary traffic signals will be used to maintain two-way traffic on Illinois 161 while it’s reduced to one lane in the work area.
Workers plan to repair the existing structure; the project is expected to be completed by mid-October.
IDOT urged motorists to be patient, reduce speed, obey all warning signs and allow for extra time when traveling through the work zone.
