You make a good point, Larry.

I may reconsider however, I would HOPE that I would never drive over it
again. Then, why woul I make it thicker. Hmmm.

How thick is the old lid? If you're thinking you'll make the lid
thicker so it wont break when you drive over it again, keep in mind
that that just means the tank may break instead. Personally, I'd
rather have the lid break...

Oh, and I come up with a figure of about 940 pounds for your lid (just
the concrete)... But then you do have a backhoe, so maybe that's OK...
