How do I build a bridge on a bend? Do I have to build from scratch
or are there any kits (or even ready made)? I can find lots of
straight bridge kits but nothing on a curve. Oh, and I want a
bridge, not a trestle
There's at least a couple of curved bridges in NZ..
But as previously pointed out, they are a series of straight section,
arranged in a curve
One the most famous arched Railway bridges in Europe to be
constructed on a curve is the Landwasser viaduct in Switzerland.
However this shot
shows that this too is actually straight sections set at angles to get
the curve. Piers can be built thicker on one side relatively easily
but constructing an arch that has further to span on one side than the
other is quite a complicated excerise .You are basically constructing
a segment of a horizontal cone.

Of course concrete is probably the easiest medium.
Kids will know it from the Harry Potter movies, where the flying car
