To help pay for the $350,000 cost of construction, Royal Gorge bridge was in fact built as a toll bridge, and is simply meant as a tourist attraction, not for traversing.
By the way, we have the tallest bridge that supports cars to go over it, but Colorada beats us with being the tallest bridge(not a bridge that supports cars). New River Gorge Bridge is still a better bridge though ;3.
