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.
