Well there's Wayne Hussey's bridge which was built out of znap
http://news.lugnet.com/trains/?n=6992 it's a bit longer than you need, but I
imagine it would've been impossible to use if it had a twisting problem.
Maybe you could adapt his deck construction technique?
Also I built this small bridge
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=13433 which is very stable,
and could be extended and widened quite easily.
