As of midnight (9/14 to 9/15), I-10 westbound at around mile marker 175 (Prairieville/Geismar/Gonzales) was bumper to bumper with people moving forward a few feet every minute or so. Airline Highway (Hwy 61) was bumper to bumper through Gonzales, but there was a little separation at each light. Traffic on secondary roads wasn't bad at all.
