Absolutely lovely!!!!! I had no idea you could stop and walk across it. The staff in the Casino told me about it. So, on your way back from Vegas to Phoenix my friends, exit off of US93 via Exit 2 and follow the signs to the dam. Then after the security checkpoint you will veer off where the arrowed sign says, "Walking Bridge."
You will start in Nevada and walk right up to the AZ State Border. Tons of photo ops. It is not that far of a walk and the views are amazing. Beware, it gets pretty windy though.
What a special place. The only thing that disgusted me is that at the end of the walk there is a cement block like structure stopping you from going any further. Some people have chosen to Graffiti up and write on the wall. Nothing gross or anything, kids stuff. However, shame on them and their parents for allowing it.
