Looks like the three old WTMJ towers in Greefield have been taken down. Like the old WCFL towers, each was a different design. The tall ND tower was a self suporting tower with non tapered tower sections topped by tapered tower sections. Somewhere, I read that it was 580 feet, but I can't find that now. I thought it had been used for the original TV station, but I'm not sure now. Looks like it was near Blue Mound Rd. and Calhoun Rd. Maybe Chris, Kent, or Jeremy know more.
