I am wanting to build an ATV/Riding mower creek bridge with some of the materials I have lying around.
The bridge would be 16' long and 4' wide, with an unsupported portion of about 12'.
I have been toying working with a windfall fir tree that I cut in half for the beams. These are shown with dimensions in the images below. I have a bunch of 2X6 boards that were lying around for the decking. I also have PT 6"x8" "posts" that I could use for center supports, but not sure how well those posts will set in the creek (I could set them in concrete in the summer time when it is dry, but not sure how they hold up under constant water). What are your thoughts? The beams would be about 3'-4' apart with the 2x6 cut into 4' lengths going cross wise the entire distance.
