A section of Route 53, which is runs in front of the Illinois State Police headquarters, was renamed to honor the state trooper who was killed in the line of duty in 1969.
Pritzker was joined by the Warner family and other state officials at the commemoration ceremony.
"With the establishment of the Trooper Richard G. Warner Memorial Highway, everyone who drives through this region will know his name – a fitting honor for a man who was a cornerstone of his community," Pritzker said.
