LA Highways Close For Repairs (1987)
LA disc jockey Steve Morris announced on KRTH-FM that freeways in Los Angeles and Orange counties would be closed for major repairs from April 8 to May 1 so that road crews could work nonstop. Morris discussed the news throughout his morning show, from 6:30 to 9:30 a.m., until finally he announced, "April Fool!"
The radio station, Caltrans, and the California Highway Patrol all received hundreds of calls in response to the announcement. KRTH later admitted that it was stunned by the reaction to the hoax and revealed that it had received a call from Caltrans "telling us that they didn't think it was very funny."
