Started digging and found the short in the wiring from my house that
runs 50 feet ± to the greenhouse. Standard 10-3 w/ ground (4 conductors
total) NOT direct burial. It's probably been there for about 40 years.

While I know the right solution (replace with direct burial, or conduit)
I do have to drill/fish/pull etc. under a 14 foot wide asphalt
driveway. If this were direct burial, or there any approved splice
methods that can be buried (2 foot cover) OR do I need to place a
utility box over the splice.

Any ideas appreciated.

There is a splice kit sold at the electrical supply
houses that consists of an insulator with metal tubes
that have socket head screws for clamping down on the
wires and a piece of heat shrink tubing coated on the
inside with a hot melt sealer that slips over the splice
when it's finished. The setup works very well.

Several manufacturers produce them.
