If you can't get up there early enough, let me give you some advice. If you're coming from Metairie area, cross over to the Westbank on the Huey and cross back over to the Eastbank on the CCC. Take the 1st exit off of the CCC on the EB side. This will go MUCH faster than trying to get off at any of the exits heading towards the WB coming from the Eastbank. There have been years I've overslept and sat in traffic on 10 forever trying to get off at either the St. Charles or Tchoup exits, and by sleep in, I mean like 10am LOL
A friend told me that the traffic coming from the WB side is MUCH MUCH lighter.
Or another tip is to use surface streets. I got from Old Metairie to Washington and St. Charles on Bacchus Sunday at about 1pm in about 20 minutes. Just took Palmetto to Washington Ave all the way to St. Charles. Sure, most of that is ghetto, but it's a Sunday morning and there are a lot of people out and about. Just don't stop to buy any drugs and you'll be alright
You'd be surprised at how fast you can get around on back streets since even a lot of locals only know the major thoroughfares.
