16th Century Bridge Building Animation

[Rail and Tie]

Ever wonder how they constructed those stone bridges before the day of steam?
Must have been an army of masons...

Darn copy and past from Youtube does that every time. Thanks Tom.

Loved the video.....labor was relatively cheap, relative to the total project cost, in those days and allowed the designs to be a bit more labor intensive than projects today.

Thanx Darryl

I'd never thought about how they did it.  Really cool video.  Thanks for the link.

I want to know how they removed those pilings that were driven down to refusal.  Perhaps a long lever?  Placed on what?  Inquiring minds want to know.

Cool video none the less.

I was thinking the same thing. How'd you remove those posts. Plus building right on the bottom of the river bed. I'm thinking the foundation would have sunk into the mud. Some where on the net has got to be something about them building the Brooklyn Bridge way back when.

PBS did a show of the building of the Brooklyn Bridge.  They used caissons with guys at the bottom mucking it out by hand.  A number of them died of the bends, if I recall corrected.

Hey Darryl:

Really cool animation. I really enjoyed watching it.

The Romans understood and constructed cofferdams, and they'd schedule the piers for when the river was at its low point. I think there's pictures on Trajan's Column.  We've driven across a couple of Roman bridges in Spain and France.

You learn something 'old' everyday.  That was an awesome video.  Love this hobby for all the things you learn out of nowhere.
