In April of last year, the 34 year old Weist, of Viola, was setting up spike strips south of Alpha when a car that was being chased by police hit and killed him.
The honor for Weist was approved by the Illinois General Assembly, and sponsored by Representative Dan Swanson of Alpha and Senator Mike Halpin of Rock Island.
The suspected driver of the car, 24 year old Daylon Richardson, faces murder and other charges, and is scheduled to go on trial in Henry County in October.
The dedication ceremony will be held in AlWood Elementary School, in Alpha, on Saturday at 11:45 am.
