Yes they still have them or they did a couple years ago.
An interesting tidbit about IH10 is that when you get on I-10 at it’s beginning in
West Tx you’ll drive almost 878 miles until you cross the Sabine River into LA.
It’s somewhere around 44 miles across Houston on I-10 some of which is basically
the city limit just following the Interstate on the north/south sides to
get commercial property..
I would have though it was more like 80 miles across than 40 . We don’t take I10 east very often but we take 288 south often and I45 north pretty often but I have never checked the mileage.
I was born here in 1940 I have seen a lot of change in Houston.
