But this wasn't always the case.
You see, back in the 50's or so, an engineer decided to put a road right through the falls. One of the columns was in the waterfall. It wasn't a pretty bridge at all. It was just a sturdy road. The park that was beneath it was neglected and actually a bit dangerous to go to since it was so isolated.
Finally, city planners decided to revitalize the downtown area. The road bridge was torn down and a contest began for a new pedestrian bridge to be built. They wanted to showcase the falls to visitors and not have the walking bridge detract from the Reedy River and park.
They chose the winning design well.
It's a suspension bridge. There are no support columns directly beneath it.
