The Bridge will have 5 4x4 on each side spcaed 2 ft apart, 4 ft long with 3 ft concreted in 1 ft exposed, I will bolt a 2x8 on each side of all 4x4's and then deck it with 2x6.
I need this to be able to hold a tractor 2200 lbs.
And info would be great.

The bridge will be about 10 ft long and 8 ft wide.

Yes, it should. Maximum weight on one 2 foot span would be 2200lbs/4wheels = 550lbs. This load will be distributed on the 2x8's on one side. This will be overbuilt but that is good.

From what you gave, I would think that it should hold, due to the weight being spread over the four tires and four posts. But to be sure I would use a good and solid wood. Nothing too plyable. And make sure to keep up on the preventative maintenance.

The bridge sounds fine,
but what are those 10 columns bearing upon?
What kind of soil?
Seated how deep?
What kind of footing?
You have them so close, you must be worried.
