In Whitehouse Trucking Co. v. State (1955), 22 Ill. Ct. Cl. 126, the State had excavated sections of a highway, and workers had erected barricades and put out flares to warn oncoming vehicles of the dangerous condition of the highway. However, by the time of the accident, the flares were put out by the rain, and the barricades had blown over in a wind. The Court found that when the State removes a section of the pavement, and thereafter leaves the excavation open at the end of a day's work, it is duty bound to see that adequate warning devices are installed about the work area. In addition, the Court stated that once the warning devices are in place, it is the duty of the State to take reasonable precautions to see that such warning devices remain in place and are in working order. Whitehouse, supra.
