Engineering Marvels

thanks for posting this video John.......each of the projects seems a miracle in its own rite

Very cool and I just love this kind of stuff.  However, the pedantic gene within me couldn't help but make note of a couple of factual errors in this video. 

It mentioned the Golden Gate Bridge was connected to "Marin County."  It was mispronounced and the correct pronunciation is "Mah-ren."  It also said the Salesforce Building is 1070 meters tall or 3,510 feet.  It is 1070 feet tall and not meters.  

A somewhat different Engineering Marvel.

@david-green startling and amazing !!!!

I believe this series airs reruns periodically ......if you ever have the opportunity to do so, you may wish to have a look at this in-depth documentary style presentation of the construction of this bridge.....Modern Marvels Lake Pontchartrain Causeway S09E49 Episode aired Oct 15, 2003

here,a small sampling of the completed bridge/causeway

The conditions involved in building this causeway were incredibly difficult as a major part of it was built in the bayous teeming with alligators.

Very interesting.
