It cost's quite a bit more than that to install those. The entire corner of the sidewalk at the intersection has to be demolished and a new one installed. You couldn't even get the old concrete jackhammered out for that.

If I'm not mistaken, I believe Philadelphia has already done the curb cuts and installed the ramps. I recall Philly having a big issue with the ADA over this about 10-12 years ago.

Typically, they still jackhammer out the old ramps and pour new ones with the composite truncated domes or the pour a new one with a void in which to place the truncated dome pavers over a sand base. It's an insane waste of money.
