I was about to say the same thing. The Austonian will stay the tallest unless they add more to the tower. Though this tower will look taller due to the ground being higher.
Once it starts construction they said it would only take a year to build. Wow talk about super fast for a tower that size. Also correct me if im wrong but since this is state owned and controlled land, the city of Austin will have little to no say in zoning or height. I can just see a bunch of NIMBYS raising hell over this since its fairly close to the capital.
