Greetings,

If it has really sunk 6" you might consider pouring another 4-6" of
concrete on top of the existing sidewalk. This way you get a brand-new
looking sidewalk a foot thick.

Hope this helps,

Very good idea. Probably a lot cheaper than any other fix. It doesn't
address the sinking problem but then I suspect that most of the
'sinking' is due to the ground building up over the years. Unlikely
that such a large section of 'crete' would sink evenly without serious
cracking and uneveness.
