And you've probably seen it on TV

Used in many television commercials you have probably seen an aerial of this bridge. If you looked closely you may have noticed the road below from where these shots were taken. The bridge is about a mile long and most people driving over it the first time don't even know they are on a bridge. Probably too busy noticing the view. The bridge is wide enough at the top that you never see enough to know you are not on an embankment.
