I believe the I-71 bridge is called the Jeremiah Morrow Bridge.
It's a running joke in our family, every time we drive over it, I say "did you know this is the tallest bridge in the world?". And my kids say "oh reeeeaaalllly" (which goes back to me saying back in the day "I can't remember if this is the tallest bridge in Ohio, in the US, or in the world?").
We laugh at really stupid stuff.
And to try to get on topic, I saw a Mega Structures episode on TLC/Discovery Channel that described the building of the Millau Viaduct. It was quite the engineering and construction challenge.
