Can you give me some context? What excerpt?
The dashes should be inserted between "bridge" and "an", and the second dash should be between "gorge" and "while".
Without the hyphens, the sentence is a bit too long and over-connected. There needs to be some sort of pause to describe the bridge the jumper is jumping off of.
