Correction: 4x6x16', not 2x6x16'! (hahaha)
3' on each side is supported, 10' is in between.

Before adding the fifth.

4x6x16 might be marginally OK for a 1500# bare tractor.
Span load carrying capability comes from the depth of the beam.
4x8 would be better, and 4x10 or 4x12 much better.

The list can go on and on of what could be better, but where is the threshold of overkill to get me to the other side to cut grass and carry tree trimmings?
Its not a logging or oil lease road over rushing water.

To put it in proper perspective:
You seem to be bridge building at the threshold of "underkill".

And your math to support your definition of "underkill" relevant to its usage is?
Proper perspective? You seem....? Wow..... :ROFLMAO:

Perhaps you should read your original post.
Why did you even make your original post, if you already knew what you were going to use?

Many of the smaller wood decked bridges around here used 2x6's on edge for the deck.
These were then oiled and or tar and stoned over the tops.
Another option that I have seen used for bridging are large truck boxes, either dumps for narrower bridges or a pair of flat beds side by side for wider ones.
With the price of lumber a used 48ft flat bed would probably be cheaper

My response to the OP was simply in regards to having a similar project. Positively participating in a Forum, that is all. No where was I looking for analysis to hijack the OP's thread. Nor was I telling him what to do. Thank you "Super Member".

fried, quit pushing people away from participating, bud! Bones' bridge looks fine for a SCUT Massey. And if it fails, he'll live.

Here is a really good resource for bridge building that has information on building bridged from used telephone poles as well as others.
I've also researched using a shipping container as they support an incredible amount of weight on the corner points. Godd it an you will see some very creative examples of converting shipping containers into covered bridges!

The OP asked for information/opinion.....now he (and you) don't like the result?
I assume this site to be fact based.
In my world, warm and fuzzys are for politicians.
