In Webee v. State (1985), 38 Ill. Ct. Cl. 164, the Court was presented with a downed stop sign case. In that case, two cars collided at an intersection where the stop sign that was maintained by IDOT was down. There was no evidence that the State had actual notice of the missing stop sign. In the Webee case, we found that "the evidence at trial indicated that the sign was missing for a period of a month, possibly as long as six weeks." Id. at 168.
