Leonardo Da Vinci's Bridge(s) [View all]
A group at MIT has built a scale model of the (rejected) bridge design which Leonardo Da Vinci proposed to bridge the Golden Horn about 500 years ago.
The MIT folk point out how many advanced design features it had, and postulate that had it been built it would have changed civil engineering. A variant of such a bridge was built by the Norwegians in 2001

They make no mention of several other of Da Vinci's bridge designs which, it seems to this non-engineer, are also astounding.
One was a bridge which was self-supporting during construction, and which several people have built
Another was for a parabolic swing bridge

Brilliant, was our Leo!
