Here is one photo of my lift bridge that has a 32" span (approximately):

It holds up very well, and i assume that you could make it even longer if
you needed to.

I want to build a bridge to cross a one-meter gap between two train
platforms.  The bridge must hold two straight lengths of track, spaced
with one trackwidth between them (the distance there would be if you
snapped two cross-intersection track pieces together).

The platforms themselves are a meter off the ground, so putting a
support in the middle of the span isn't feasible.

Two years ago I grabbed one of every Znap set from a TRU clearance.
I've been using that to try to build a beam bridge.  I've gotten the
beam reasonably rigid, but my problem right now is that it twists very
easily, and I can't figure out how to support against that.

Any tips on how to build a sturdy one-meter-long bridge out of Znap
and/or Technic while being somewhat miserly with the pieces, so I don't
run out?  And any tips on how to reinforce against twisting would be
greatly appreciated, thanks!
