Rebar cattleguard

[slowa]

What is schedule 40 rebar?

Sorry, Grade 40.

Got the rating from here...

5/8 in. x 10 ft. Rebar-182478 at The Home Depot

It's a concrete truck!

And they will have the same axle load that any other truck will have

I understand, but what would be the normal traffic?
It'd be easy enough to put a by-pass gate in for that too heavy business.

I wasn't questioning the depth, only what the actual outer dimensions were.

How often does a cement truck need to drive over that bridge? And what would be 'normal' traffic?
If that cement truck only needs a few passes for one project then open a separate roadway around it.

I am thinking 12 x 6 feet with the ends sitting on 8 inch wide concrete block walls.

The cement truck would be once in a blue moon. Everyday traffic would be a few pick-ups or a compact tractor, rarely exceeding 8,000 lbs.

The separate roadway for heavy machinery may be the simplest option. The easement is about 20 feet wide against the neighbors fence line, so I may be able to fork the road at the cattle guard.

CMU is a poor choice also.

And please, it's concrete!!!!!!!!!!!!!!!!!

I take it you mean I should pour the wall and not start with blocks?

The rebar plan above is based on this plan

Which I simplified to

I priced the steel pipe at my local plumbing supply place and online at metal suppliers and I could hire a part time security guard to stand watch for the same price.

I want to build my dream home for $50/sq ft but it isn't likely to happen.

Good grief. The OP is looking for assistance, and you're too busy correcting him on trivialities to actually help.

6x12!!!!
Ain't gonna happen with that design.
Keep in mind anything you lay on top of that pit has to be completely self supporting and any bolting you do is only to keep it from vibrating out of place.

You can't just stack some concrete blocks up for a foundation wall on a road way.

Have you thought about just putting a gate in?

Would storm inlet grates work for your use? They aren't cheap, but if you contact some road builders, they probably have some in there bone yards. They can be hard to scrap (need a letter from city/county Public Works departments) and often road builders will have some old ones around. I would support them on 8" wide reinforced concrete footer, that locks them in; not CMUs.
