Kingston,Mi | I would put it on foundations that line up with the placement of the trucks that were under it. i did some quick calculations, guessing at the weight of the car and your truck trailer. If the car weighs 40,000 and your truck loaded is 80,000 plus a saftey factor of at least 25% then the foundations have to carry 150,000 pounds. If the subsoil will carry 3000 ponds per sqaure ft. then you would need a total of 50 square ft between the 2 foundations. Since we are this far along and I am not an engineer I think you should take your final calculations of bridge weight and truck weight to an engineer and have them check for claring mistakes.
Something about the small size of the footing is disturbing. A couple of hours of an engineers time seems like a very wise percaution. | |

How would you set a Bridge ??
