Over the past year, the best route is largely dependent on construction. Putting the utilities underground has resulted in long backups around Grand Case and the Dutch Quarter and one never knows how bad the backup will be that day.

I learned from advice from others in November after hour-long delays in Grand Case that the best thing by far is to use an app like Waze or Google Maps and let it advise you of the best route AT THAT TIME! Worked well for us in April as well since the construction work continues - worse in Dutch Quarter lately.
