At 4 p.m., the state reverses the inbound lanes so that all traffic is headed outbound. The idea is to avoid some of the horrendous traffic jams that New Orleans experienced before Hurricane Ivan, 11 months earlier.
That didn't happen, I can tell you that right now.
I drove home, near downtown New Orleans, at around 9 pm on Saturday night and I took I-10 to do it which means Contraflow couldn't have been going then. I was out of the city at 4 pm so I suppose its possible they only opened Contraflow for 4 hours which doesn't really seem logical.
On Sunday, New Orleans Mayor Ray Nagin calls for a mandatory evacuation.
On Sunday, at 2 pm he did yes. I was in my car evacuating myself when they called for the mandatory evacuation. That was little over 12 hours before the storm hit the city.
Some other things you should consider:
1) The city has a plan to evacuate people before the storm hits by bus which they didn't do.
2) If they city really began preparing for this storm 4 days ahead and planned to use the Superdome, why didn't they put
ANY food and water at the Superdome? Are you insinuating that they couldn't get any food or water to the dome within those 4 days? The city opened the Superdome to people at around 1 pm on Sunday (at least that's when I heard it on the radio). If they didn't intend to use the buses to get people out, could they not have rounded up water or anything else to take to the dome?
3) Contraflow helped, but it was still horrible. It was taking people hours to go 8 miles from the I-10 I-610 split to the Clearview Parkway exit which is where Contraflow began.
4) Alternate routes were worse. You couldn't go east to Mississippi and then north because Mississippi State Police shut it down to get their people out of harm's way.
4b) I took airline highway, it was backed up for over 15 miles solid with 3 lanes of traffic 15 hours before the storm hit. People were out of their cars just sitting on the highway. I wound up taking the back streets out of the city and it still took me an hour and a half to go 25 miles. The link below will show you how far that is. The traffic was backed up from Tulane Ave in the city to I-310.

The pink line doesn't extend quite that far but that is how far traffic extends because the only way to get to an interstate off of airline is to hit I-310 when Contraflow is going the other options are eliminted
5) Consider all of that for a moment if you will. Traffic backed up for 15 miles 3 lanes wide on Airline. Traffic baked up for 5+ hours on I-10 with Contraflow working. And
125,000 people DIDN'T evacuate. Can you imagine how much worse it would have been if they tried to? People would have been sitting in their cars with the hurricane passing over the top of them.
