McHenry County recently offered an update on the Randall Road Improvement Project.
For the past two months, survey crews have working within the corridor to obtain the necessary topographical data necessary as the project moves into final design (known as Phase II). These crews will continue to work over the next couple of months to complete this task. This topographical data will help to determine the detailed aspects of the design in order to prepare the contract plans required to construct the improvements.

In addition to the survey crews, geotechnical crews are obtaining soil and pavement borings. These borings will be analyzed which will help determine the necessary pavement structure and type of pavement. The borings will also be used to design any necessary retaining walls, bridges and culverts. Temporary lane closures will be used to obtain some of the borings. The geotechnical work is anticipated to continue through mid-August.
With the presence of these crews and the temporary lane closures, the county encourages motorists to exercise additional caution when driving within the Randall Road corridor.
Earlier this week on the morning of Tuesday, July 8, the traffic signal at Randall Road and Algonquin Road intersection went down.
This resulted in the signal flashing and the intersection was required to operate as a four-way stop controlled intersection.
The county's signal maintenance contractor responded immediately to temporarily fix the problem until a permanent fix could be made the following day. It was determined that the cause of the event was a failed electrical cable within a metal conduit.
The failed cable was not related to any of the ongoing survey or geotechnical work.
The county is aware that this issue caused some inconvenience and appreciates the motorists understanding and patience.
