CmdrK, I try not to think how high we are when we go over the bridge.
Here's a photo I took (and showed here are few years ago) of the Pat Tillman bridge being built. I told myself then I wouldn't drive across it when it was finished, but it beats making a long detour to get to Las Vegas, NV from our house in Arizona. Actually, when you're on the new bridge, you have no idea it's that high because you can't see over the edge. Thank goodness.
