"I seriously thought the Texas folks would show us how things are done right. I'm hoping they do. They claim they have contracted fuel trucks to run along highways and get gas to those running out. Part of the plan they say. I hope so."
And exactly how do these trucks get through the traffic jams?
I would presume gas trucks would head down the southbound lanes and put gas in jerry cans and carry it to stalled vehicles. But I also imagine any such truck stopping will be overwhelmed by other drivers who are short of gas and just haven't run out yet. Definitely a tense, volatile situation.
After this is all over, I would expect that they will put permanent gates at freeway entrances that can be easily closed to prevent access once contraflow is introduced. I haven't traveled I-45 north of Houston in about 10 years, but back then you could move off the highway to the frontage road just by going across a grassy strip and concrete curb. Don't know whether they have it fenced now or not.
