driveway crevasse

The snow has been giving way to warm temperatures this week..which has led us to trouble and a dilemma. We need 10 more sheets of drywall to finish all of the inside of the house and I am scared to attempt to drive over this crevasse..it is on the lower part of the hill on the private road..I noticed it developing a couple days ago and I was so scared to drive over it last night that I didn’t even drive in..I got to it and turned around..it snowed last night so it does not look as bad but it was a mini-river last night…well A* and I took a walk to look at it today to gauge our options..and they are somewhat limited.

I've got a bad feeling about this..

the gap is around 12-18 inches wide and 18-24 inches deep..and it is winding down the road so there is no way around it…only over it.Either way something has got to give cause the drywalling needs to be done. DONE!
