More than 1500 MidAmerican customers were without power in Marion County yesterday after a power pole went down. The guy-wire became unattached to the pole at around 7:50am in front of the National Sprint Car Hall of Fame. MidAmerican Energy, the Knoxville Police Department, and the Marion County Sheriff’s Office responded to the scene. The Knoxville Police Department also directed traffic at malfunctioning stoplights. Power was restored after about an hour.
