Bob, from the late 60's onward I have wondered why a city of that size had so few major roads. Your filling in the blanks.
I use a route similar to Oki to get down south, as I hate the drive on 35. Very crowded from Austin to the split at I-35e and I-35 West. I only went that way to stop at Buc-ee's. Never again. Did see your exit in Austin to the SE.
