a photo of bridge built in 2000. i laid down 3 carefully selected heavily creosoted poles on a bed of gravel to span the creek. they were placed to match up with the factory pre-drilled holes in the 8 ft. cross arms. these holes are 5/8 inch. positioning the arms i then drilled a 1/2 in. hole 8 to 10 inches deep into the pole. using a 5/8 inch bolt with a square washer and 12 inch long bolt i used a sledge hammer to drive the 5/8 bolt into the 1/2 inch hole. i continued until i spanned the creek. next i bolted a heavy timber to each side of the span to tie it all together. the uprights are not structural just visual. all was used material, it hasn't moved and still sound.

it does get a lot of runoff from my pond and neighbor's pond overflow. after one heavy rain a limb had created a dam at the bridge and it flowed over it but did not move it.
 
actually that is a culvert and not a bridge as the span is less than 20 ft.--Looks very sturdy!!
 
Nice bridge. Several years ago I supervised a YCC(Youth Conservation Corps) working for the DNR. The game-area manager dropped two steel beams to span a creek for tractor traffic. We poured concrete supports on both sides. The kids all wondered how we were going to move the beams by hand. I remembered we cut some cedar post in a parking area so we got the drop offs. We lifted one end of the beam and put a cedar piece under it. Then we lifted the other end and as we moved the beam we placed more pieces in front. We rolled that beam and sailed it out over the span as pretty as a picture. For a foot bridge while I wondered how we were going to move two telephone poles, they lifted one all together and carried it to the stream. It was a fun summer.
