For those of you who are not familiar with HOUSTON. Their traffic is always bad.. this is just extra bad... but on 45 the contra is open at 1488- 125 miles to Buffalo TX
They've set up I-16 in GA for contraflow with gates at all the ramps. It seems to work pretty well.
I have friends in Spring (about 40 min. from downtown Houston). Not that close to the coast. Do you happen to know if Spring is part of the evacuation area?
