With ONE very glaring exception. Texas had no "contraflow" plan in place to make all lanes of Interstate highway AWAY from the coast "one-way-only"---hence the massive traffic jams .
Louisiana DID have and implement such a plan, and the evacuation of those with personal transport went MUCH more smoothly.

Contraflow would have done little to alleviate the massive traffic jams. Highways bottleneck outside urban areas no matter how you plan it. Contraflow was only practicle outside Beltway 8, and then had to be coordinated with other cities, counties etc. People who used other than main highways had far fewer problems with traffic.
