There is no city that runs through the Royal Gorge. The Royal Gorge is a tourist attraction in Colorado that is mainly a large suspension bridge and a tramway that go across the Arkansas River approximately 1600 feet above the surface of the water, and an inclined railroad that goes down to the river from the top of the gorge. The bridge and tramway really don't go anywhere but to the other side of the gorge where there is a tourist shop. The closest city to the Royal Gorge is Canon City, Colorado, but it is several miles away.
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.
