How did they tunnel through water to Catalina Island?
This tunnel under San Francisco Bay carries commuters on the subway between Oakland and San Francisco, and is one of the longest immersed tunnels in the world. Immersed tunnels are constructed using pre-made tubes that are floated to the location and sunk into place. The segments are then attached under water.

Nuculer, of course.
If you were pushing melted rock it would still be that hot, so I can't see how that would help.
ETA: To clarify, I'm not arguing with you, just adding to what you said.

But theoretically it would melt as it drills, creating a hardened tunnel of compressed rock and dirt on the outer circumference that would support the tunnel itself. If that is the case you wouldn't need to remove any dirt because it would be compressed and melted into the tunnel wall exterior.

Same way they tunneled under the English channel ,I suppose, if that is true.
