For anyone who has driven over the incredible Hoover Dam, you know the process can be a little tedious. Your car first cuts back and forth *down* to the dam, then across, then cuts back and forth *back up* the other side…all in snail’s-pace traffic, and all in 118-degree heat.
I still laugh thinking about how my friend Dave Scales and I once got into a huge argument in that gridlock and heat, arguing about biofuels or presidential history or some such thing that you only argue about in extreme heat.
But! That ridiculous argument needn’t have happened, had we been driving over the Hoover Dam in 2010. Check out the engineering behind the new Hoover Dam Bypass Bridge.
