1. This is badly needed.
2. They’ll need to add a third lane in each direction between 1826 and South View Road to make 3x3 work. Surprised they didn’t plan for this when designing the Oak Hill Parkway.
3. I’m also shocked that they are not including a Dripping Springs bypass loop as part of the design, given that the state has prioritized small town freeway bypasses over the last two decades. Is there a separate project for that?
4. Surprised they haven't gotten pushback about the lack of bridge at Ledge Stone/Hargraves into Belterra Village. As the only major retail destination in the area, you'd think there would be access from both sides. That Belterra/Heritage Oaks turnaround is going to be BUSY from anyone coming to Belterra Village from the east AND the 2,000+ people who live in Ledge Stone north of 290 that you're forcing to use this specific route into the city AND to their shopping destination. The only way in and out of that neighborhood is Ledge Stone. IMHO, it's a bad choice. The Heritage Oaks/Belterra intersection is going to end up underdesigned and overused. I suppose they may be trying to cut down on people cutting through the shopping center from the south to make it to the intersection, but that's ridiculous: anyone from the south has two better paths to choose from: Nutty Brown or Belterra and even Belterra Village Way would be a better choice than Hargraves to access 290.
Last Edit:
I navigated to the other forum to see some of the comments, and am glad to see I am not the only one who thinks some of what I wrote above:

My observations
While the project limits have been extended to be west of RM 12 in Dripping Springs, the freeway stops on the east side of Dripping Springs, and the proposed facility in Dripping Springs is just a plain six-lane street, and has three traffic signals shown. The signalized intersections look underdesigned to me, for example I would expect the left turn from westbound 290 to southbound RM 12 to have two lanes (but it has only one). The lack of a freeway or bypass in Dripping Springs is a disappointment and is sure to be a problem point, probably immediately after the project is built.
The right-of-way width has been reduced from the originally proposed 400-foot-wide corridor (122m) to a typical 321 feet (98m) shown in the presentation. However, it appears to be mostly between 300 and 321 feet, including one section west of Trautwein road which is shown as 240 feet and has zero space between the main lanes and frontage roads.
Due to the narrow right-of-way, there is a center barrier with no median and minimal space between the main lanes and frontage roads, which will make it difficult or impossible to add lanes in the future. Of course, Austin has never planned for future growth, so this is not unexpected.
The narrow corridor leaves little or no space for landscaping
The east end of the project has a 2.6-mile-long section with no crossings. (Spring Valley to West View)
The freeway design is very basic and routine. All intersections except one are standard overpasses (main lanes on top), and there is one underpass with the main lanes on bottom.
Echostatic speculated a cost of $2 billion, but I think that is too high. This is all plain-jane basic freeway, nothing fancy, so I'm thinking more like between $1 and $1.5 billion
In spite of the disappointing design features, I still hope to see this proceed. After all this is Austin where it is difficult to build anything, and you need to take what you can get. Planning for this corridor is decades late, so we can expect the planning failure to have some consequences.
