Don't be alarmed to see workers removing the massive OneAmerica sign from atop the 38-story OneAmerica Tower in the next few days. The company plans to replace the sign with one that will show better in skyline shots during major sporting events. The sign will look roughly the same but could have a different type of neon, depending on what looks best and is most readable, said OneAmerica spokeswoman Jessica Mace. The sign replacement project is slated for completion in October. The huge logo was added to the city's second tallest skyscraper in September 2004. Originally the AUL Tower, the building was completed in 1982.
