Yes it's on the outlet end, about 12 ft from the final outlet, but I
just want to dig up a few feet and replace that part.

OK I'll use the heavier stuff (on the repair section) so it's stronger
at that spot,

But my real question is how to connect the new section to the old
section?

For example, maybe the pros use some sort of sleeve to connect the
sections of corrugated pipe, secured and sealed by a sort of epoxy?

hard to tell form here but assume this is the outlet end of the drain
system so your heading towards daylight down the driveway somewhere

how deep is the pipe?

That corrugated plastic drain pipe cannot support much load, if it's
close to the surface & you have a good choise of driving on it again
might be advisable to switch to SCH 40 or even SCH 80 PVC in the
locations that are likely to be damaged.

if the pipe is REAL close to the edge you might be able to tuck it
under the driveway to protect it.......but now the edge of the driveway
has less support


i think I'd go w/ PVC, unless your vehicles are real haevy weights
that should do it

If you want ot do it cheaper consider ABS. Maybe a little crush test
is in order
