I worked at the Skyway, late 70s early 80s. Correction: The box office was on ground level. An escalator took you to the second level where Skyway 1 was. Another escalator took you up to a third level where Skyway 2 was. Skyway 3 was a smaller theater on the same level as Skyway 1. The theater that was added on the ground level was Skyway 4. (I was working there when they opened Skyway 4, around 1980). I believed they split Skyway 2 right down the middle, and they turned balcony of Skyway 1 into a separate theater.
