Answer:  Your answer comes from from University of Kentucky Public Relations/Marketing Executive Director Jay Blanton: 

 The towers along Cooper Drive are for electric service for new hospital. Some 65 percent of the cable for this project has gone underground. But in that particular area, we are going through what might be a future building site, so rather than put them underground when we later might have to move them (a very costly proposition), we decided upon elevated lines at that point.
