Roadworks?

I,m setting off at 3;30 am tomorrow Newark to Gatwick i just wondered if anyone knows of anything that might trouble me on the way?, i havent been that way for about 8 months.

I,m going A1, M11, M25 ,M23.

I was also hoping to go over the Dartford through the auto pay thing how much is it for a car?.

Dartford is a quid for a car still I think Jammy, and apart from some roadworks on the A1, and the usual overnight lane closures on the M25, you should be ok at that time of the day.
