in the United States and Peoria-Bloomington is the 117th largest television market in the United States. The area has 14 commercial radio stations with six owners among them; four non-commercial full-power radio stations, each separately owned; five commercial television stations with two operating owners among them; one non-commercial television station; and one daily newspaper (Peoria Journal Star). NOAA Weather Radio NOAA Weather Radio station WXJ71 transmits from East Peoria and is licensed to NOAA's National Weather Service Central Illinois Weather Forecast Office at Lincoln, broadcasting on a frequency of 162.475 mHz (channel 4 on most newer weather radios, and most SAME weather radios). The station activates the SAME tone alarm feature and a 1050 Hz tone activating older radios (except for AMBER Alerts, using the SAME feature only) for hazardous weather and non-weather warnings and emergencies, along with selected weather watches, for the Illinois counties of Fulton, Knox, Marshall, Mason, McLean, Peoria, Putnam, Stark, Tazewell, and Woodford. Weather permitting, a tone alarm test of both the SAME and 1050 Hz tone features are conducted every Wednesday between 11 AM and noon. Infrastructure Health and medicine The health-care industry accounts for at least 25% of Peoria's economy. The city has three major hospitals: OSF Saint Francis Medical Center, UnityPoint Health – Methodist, and UnityPoint Health – Proctor. In addition, the Children's Hospital of Illinois, the University of Illinois College of Medicine at Peoria, and the Midwest Affiliate of St. Jude Children's Research Hospital are located in the city. The hospitals are all located in a medical district around the junction of Interstate 74 and Knoxville Avenue, adjacent to downtown in the southeast of the city, except for UnityPoint Health – Proctor in the geographic center of the city. The surrounding towns are also supported by UnityPoint Health – Proctor, Pekin Hospital, Advocate Eureka Hospital, and the Hopedale Medical Complex. The Institute of Physical Medicine and Rehabilitation was created from the "Peoria Plan for Human Rehabilitation," a model for medical and occupational rehabilitation launched in 1943 to integrate returning World War II veterans back into the workplace. Transportation Interstate and U.S. routes The Peoria area is served by three Interstate highways: Interstate 74, which runs from northwest to southeast through the downtown area, Interstate 474, a southern bypass of I-74 through portions of Peoria and the suburbs of Bartonville and Creve Coeur, and Interstate 155, which runs south from I-74 in Morton
