creating a culvert

[paulsharvey]

That old pipe had Way too little cover over it. If you kinda clear the material off the top, you could try to uncollapse the pipe, and put it back in, this time, get your atleast 12-18" cover over it. It's hard to tell, but the creek looks like it has a muddy soft bottom, so just sloping approach back and driving through is probably not a good idea, unless you add rock.

Ok, got some pics. Tons of leaves make seeing it difficult. 1st pic shows path. right to left id 8'
2nd pic shows left side of culvert, board is just to right of crushed/split pipe.
last pic shows leaf clog.. ugh

I would clean it out, then just add a bunch of fill over it and compact. See if that holds up. Don’t dig anything up if you can help it.
