A Fear of Heights


Building a structure 4,000 feet above ground is no small feat, especially for those who are afraid of heights. Nevertheless, Architect Mark Johnson was able to overcome his fear by designing the Grand Canyon Skywalk – a glass bridge with an impressive – yet scary – view, extending 70 feet past the edge of the canyon wall.

“Any time you’re around something long enough, you just get used to it,” Johnson remarks. “Plus, I figured I had to keep up with the rest of these guys.”

Engineer Bill Karren helped Johnson go to the edge and face his fear. Johnson holds no grudges, because they are good friends from the experience. Johnson knew he had to get the job done and get it done correctly and safely.

“There was no better way to ensure safety then to see if Mark could fearlessly walk across the skywalk,” Karren laughs.
