The Florence Y'all Water Tower is a water tower owned by the city of Florence, Kentucky, United States. It stands between the Florence Mall and interstate highways 75 and 71, where it is seen by millions of interstate motorists annually. The tower, built in 1974 and initially painted with the words FLORENCE MALL in giant letters, became a regional landmark after the M was changed to Y' to address legal concerns. The water tower, which can hold about , stands in Boone County in northern Kentucky, due south of Runway 18L/36R of Cincinnati/Northern Kentucky International Airport and between I-75/I-71 and Mall Circle Road, northeast of the mall. History In the early 1970s, the developers of the yet-to-be-built mall gave the land for the tower to the city, stipulating that the words "Florence Mall" be painted on it in view of interstate motorists. The tower would thus advertise the mall, which would open in September 1976. The tower was built by the Pittsburgh-Des Moines Steel Co. of Pittsburgh, Pennsylvania, and painted in 1974 by the Virginia Erection Co. The giant advertisement immediately raised legal concerns. In July 1974, state Bureau of Highways officials told the city that the tower's sign was illegal because it advertised something which didn't yet exist. Among the discussed possibilities were repainting the tower or covering the words with a large tarpaulin. With time running out to comply with the law, civil staff met for a brainstorming session at the Stringtown Restaurant with C.M. "Hop" Ewing, then mayor of Florence, who "sketched different ideas on a napkin". Ewing ultimately devised the idea of removing the vertical lines at the sides of the M in MALL, adding a stem to make it a Y and adding an apostrophe; resulting in "Y'ALL". Ewing called it a "corny solution, but cost-effective", because the minor alteration would cost one-third of a full repainting. The city paid $472 to the W.T. Marx Company of Cincinnati, Ohio, to make the changes. The publicity surrounding the Florence Y'all tower advertised the mall better than a passive sign alone. On the mall's opening day in late 1976, mall-goers created a traffic jam at the Kentucky Route 18 exit from I-75. Further developments As a general rule, water towers are cleaned about every five years and repainted about every ten. The repaintings of the Florence tower have hidden the original patchwork modification. At some point, the
