Ah, the annual balsa wood and Gorilla glue bridge building contest. (Did I say Gorilla glue? Oops! That's one secret out of the bag.)

Research past winners and take your clues from them. As Frollard says, "Triangles. Lots and lots of triangles." Or just a few large triangles and laminated beams...

Yeah, the more triangles you have, the more spread out the load. I'm thinking about a local contest where one of the finalists had a very simple, yet very strong bridge. Don't remember how much weight it took before failing. Several pounds before any deflection.
