Teacher: Now, understand the problem? Solve this instance: Question: What is the length of the interstate where KTVT originally operated? Passage:Channel 11, as KFJZ-TV, first signed on the air at 2:30 p.m. on September 11, 1955, after a launch ceremony culminating in Fort Worth oilman Sid Richardson flipping the ceremonial switch to activate the transmitter. It was the first independent station to sign on in Texas, the fourth television station to sign on in the Dallas–Fort Worth Metroplex (after NBC affiliate WBAP-TV (channel 5, now KXAS-TV), which signed on the air on September 29, 1948; ABC affiliate KBTV (channel 8, now WFAA), which debuted on September 17, 1949; and CBS affiliate KRLD-TV (channel 4, now Fox owned-and-operated station KDFW), which debuted on December 3, 1949), and the first to debut in the market since the FCC's 1952 lifting of a four-year freeze on new applications for television station licenses. Originally, Channel 11 maintained a 9½-hour per day programming schedule, starting with its sign-on at 2:30 p.m. and concluding at its midnight sign-off. The station originally operated from facilities at 4801 West Freeway (in the present-day location of Interstate 30) in Fort Worth.
