In other words, contraflow was never implemented properly or effectively.
I understand what contraflow is, but I never saw it on the TV. All traffic was on one side of the road, and basically a parking lot.
Never actually saw the 'contraflow' in effect.
Contraflow was implemented for I-10 and the causeway bridge for 24 hours only.
Sadly, New Orleans officials had a dress rehearsal for Katrina when they evacuated for Hurricane Ivan the year before.
Here is a story about the problems with the Ivan contraflow.
