Crews spent the overnight hours early Thursday replacing the sign, which read, "Alamonte Springs," which didn't have the first "T" in it.
Video from Sky 6 showed the error before the sign, on I-4 west, was replaced.
Florida transportation officials said the mistake was made by a contractor, which will cover the cost of the replacement. There's no word how much the mistake cost.
