I have attached some rough drawings for the bridge, but in a nut shell:
- I need to be able to cross in a small pick up (Ford Ranger)
- Open Span of about 30'
- I was planning to install 5 ea 6"X6" treated posts on both sides of the bridge with 2"X10"X30' bolted on both sides of the 6"X6"
- At the 1/3 span points I would have another 6"X6" angled back to the bank
- The decking would be 2"X6" with 1/4" gap in between
- Assume no soil issues
I would have liked to install a culvert and just fill it in, but it will not work. I would really like to know if A) the bridge is under designed and what I might be able to do to improve it or B ) if it is way over designed and where I could cut back to save some money or C) it's perfect!
I appreciate your help in advance and please be gentle in criticizing my drafting abilities.
