Did this journey on Good Friday, no problems. Although the A28 stops just before Rouen, you follow the Le Havre signs around Rouen and pick up the A28 just the other side. Brilliant road, not much traffic. But beware, fill up before Rouen or at the petrol station just after, there is hardly a petrol station until Alencon, only the odd emergency pump at inflated prices. If you need to spend a night there is an Etap just this side of Rouen. Don't try the Paris route, too frustrating and nowhere to stop for a pee if you hit a jam!
