Rt. 95 north

To avoid the northern Va backups and DC area you could get off at exit 104 (one above Kings Dominion) then take that road directly to 301 and follow it over the Nice bridge and the Bay Bridge until you reach Route 1 in De which ends at 95, take it north thru Wilmington and get off on Route 202 to Rt 1 south then follow to the exit for the KOA. There are traffic lights on 301 to contend with but I prefer that to the traffic on 95, also tolls on the Bay bridge and 301 by-pass in De. Good luck and safe travels.

While I agree northern VA traffic on 95 is the worst in the area.
301 is no panacea. The lights and traffic on 301 are only slightly better. The best approach would be to come thru the northern VA area midday or in the wee hours . Avoid rush hour at all cost. Weekends can be just as miserable.
