here's a pic of a little bridge that I re-built (after a propane delivery truck went through the original bridge). We had a little rain the day of this picture, and the water was actually going over the bridge at the high point - so I know that the bridge is pretty darn strong. It has four 25-foot long 18" x 12" steel I-beams spanning the creek (sunk about five feet into the banks on both sides) with 12" x 4" planks supported by 8" x 6" pressure treated beams, all held together by stainless lag bolts.
I built the bridge to perform, and it's rated for 85,000 lbs support load (but it will take a little more than that if necessary).
