I actually remember one even worse than my previous post about Alaska.
I was headed west on I-10 about 5 years ago. When I came to the point where I should have switched over to I-12 to avoid New Orleans, I didn't. I-10 along there is mostly bridges built over swamps. There were many huge holes in the road bed that a tire could fall right through. You could look down and see swamp. I don't think anybody was driving more than 30MPH - probably less. I hope its repaired by now, but I can't figure out how you'd repair it. It isn't like filling a pot hole. There's no bottom.
