Maybe put 20 of them across the creek, side by side, connected to its neighbors so a point load is shared by multiples... I wonder if putting them in an arched fashion (the ends butting into something solid, with the buttresses being slightly closer to each other than the rail is long, so that the bridge is somewhat arched) could increase the strength? or would that must make it more wobbly side-to-side...As I read the original post, it sounds like there is plenty of steel available. How many sticks were you planning to use for the bridge?
If @LD1's calcs are right (check with an engineer!) in post 30 a single rail would deflect twice as much as desirable, but if you can tie them together somehow so that the load is shared, it sounds like it could be done.
I'm still in the "get an old flatbed rail car instead" camp, though - just because something can be done doesn't mean it's going to be easy or ideal.
