Aaah, that makes a lot more sense. I’m not an Austin resident, I just drive through it once and a while. Your explanation makes a lot more sense. I never even knew there was a northern 290. I stared at an Austin map for 5 minutes, but never noticed the northern 290. I’ve driven to the airport a lot, and always connected from 71 to 290 before getting on I35 south. I even opened a TX Tag account, solely to avoid Austin.
So then the question becomes “where do they put the ‘managed lanes’ in the double deck area?” I guess that’s why it will take a lot of planning.
US 290 duplexes with I-35 from the southern intersection (Ben White Boulevard) to the norther intersection just south of US 183.
I’m guessing it’s gonna be “double deck no more.”
