95.5 (then 95-5 the Beat) was originally on a tower at GA-316 and GA-81 in Bethlehem when it moved into the market in September of 1999. At some point it moved to the same tower 97.1 the River and 97.7 TOSTR are on up in Chateau Elan near Spout Springs Road and Friendship Road (GA-347).
I want to say it happened around the same time that WYAY moved from the Chateau Elan tower to the Fish Stick, near but not to be confused with the Bethlehem tower you mention. IIRC nobody is using the Bethlehem tower for FM radio right now, although it wouldn't surprise me if it had some random class A or translator on it by now.
Both WFOX 97.1 and WWID 106.7 were on the Chateau Elan tower when they first moved in to the Atlanta market.
