ADDITIONAL INFO:
The overall color of the superstructure is yellow. At the top of the south tower, an unnamed artist has painted a series of black animal figures variously described as dinosaurs, ducks or geese. Each hand-painted figure is about six feet tall and may be plainly seen from the north shore of the Mon River. Other "unofficial" public works of art by this artist include rams painted on the roof of the Mackintosh-Hemphill building located near the bridge's south portal.
