hate to bring a dead thread back to life. Would 2X2 with .250 wall thickness be thick enough? heaviest loads I could think that would be going over these would be dual axle gravel trucks or a concrete truck.

Probably, if you have a void underneath.

FWIW, in addition to the difficulty of walking on pipe, cattle guards work because cattle and horses do not like to walk on anything hollow - pipe, wooden bridges, even septic tanks. That is why a better loading chute is solid from the ground up as opposed to just a ramp. Anything that has a hollow sound and feel to a cow's hoof will be avoided.

When I was growing up you couldn't ride the horses on top of the septic tank even though it had grass and dirt on top, and looked just like the rest of the pasture. They would get spooked and stop or turn.

Sorry for jumping in fellow TEXANS BUT, ISXNA(iksNA) on the Billy Clinton jokes, HE may be the the next first lady! YUK, OK I said it! MRS WILLIAM JEFFERSON CLINTON, x first lady, MRS PRES! What do ya'll think of that thought?
Oh yeah deep down in SOUTH TEXAS they have a gate called a bump gate, has anyone got a pic of that!

When I was a kid, back in the seventies. There was a bump gate on our deer lease. Man did I love that thing, since it was my job to get the gate. The first time we hit it I thought we were in trouble for breaking the guys gate. That was a running joke in our family for awhile.

Another interesting note on cattle guards:
When you have a cow or two that has learned to "walk a guard" you can take a light colored paint, like yellow, and paint every other pipe or rail.
They will quit walking over it.
Something to do with them being able to see the light color better so that they misjudge the gap.

And yes, there are a lot of cows and horses that fall off into them, I've had to help rescue many. Luckily, I've never personally seen one break a leg.
It probably helps that most of ours aren't very deep below the pipe.

As for the bump gate, I've (hopefully) attached a crude drawing of one.
The center post acts as a swivel with the gate attached to it and it has wires tied from one side of the post to the opposite end of the gate which causes torque to keep the gate closed.
you drive up and bump the right side of the gate with your vehicle and it swings open, if balaced right it will hang there for a few moments before pulling its self shut.
These are used more in goat and sheep country than in cattle country because a cow or horse will learn to open them eventually, sheep aren't that strong though. These gates are usually pretty darn heavy, most I've seen are about 20' wide and made with 5-6 pieces of 2X8 pressure treated boards.

That's a good drawing, I completely forgot about those until it was brought up in here.
