Criticism of small "bridge" design welcome. I live near a park that has two large hiking areas divided by a stream. If those areas were linked by a bridge the number of possible hikes that could be taken would be increased. The stream at one "crossing" is about 30 feet wide and normally has a small flow of but always enough water so you can't cross without getting wet (sometimes stones get lined up but higher water moves them. I'm guessing that at times water up to two to three feet high with flows of say 10 miles an hour can occur. Below is a scan of what I think is a simple and relatively inexpensive bridge design. How might you improve this design or is it fundamentally flawed? Thanks for any help!
