New pipe (blue PVC) is going in.  Fortunately the problems appear to be isolated to the half of the line that is closest to the house.  That means no digging back to the fence, no worries about taking out a portion of that fence, messing with the neighbor's yard, etcetera.

It also means less damage at the checkbook I am sure.

The evidence that the rest of the line is fine comes from a little test they call a hose test:  run water into the line for a while and see that the pipe routes it all quickly and completely down to the main.

Installing a cleanout at ground level where the galvanized pipe abuts the new material.
