The news article didn't cover all the reasons why Austin doesn't have a traditional freeway loop.

Obviously, Austin is famous for having local political conditions that make building super highways very difficult. OTOH, a lot of new freeways and toll roads have been built in the Austin area since the mid-1980's. Significant projects (like the US-183 expansion) are under construction.

Geography plays as much a role as any on why Austin doesn't have a loop highway. The zone immediately to the West of Austin and the MoPac is the biggest problem. You have Lake Travis, all those hills, not to mention a lot of upper income homes out there in those areas. It's about impossible to plow one half of a super highway loop through any of that.

And then the direction of development doesn't really support a standard loop. Much of the growth is moving parallel to I-35. The main routes thru Austin (I-35, US-290, US-183, TX-71) need to be improved to Interstate quality thru Austin and as far outside the city's outskirts as possible. Connector routes like TX-45 help move traffic between those main routes.

Even when the "beltway" is completed, Austin isn't gunning for a 3 digit Interstate designation, are they?

The Loop is in Chicago.

That news report has some nice historical info. And it also seemed to have pro-highway bias, since it didn't include perspective from environmental interests that oppose any and all road improvements in the Austin area.

The news report does not mention that SH 45 was originally proposed to go around the west side of Austin. I remember seeing a proposed alignment in a report from the 1970s or 1980s while doing some library searches back in the 1990s. My memory is dim, but I seem to recall it generally followed a path near Quinlan Park road.

Of course, the short section of SH 45 in southwest Austin was built. I was a student at UT-Austin in 1989-90, and I took my bicycle to the construction zone and rode through it. I seem to recall there were some delays in opening the road due to concerns about contaminated runoff water, and that section of SH 45 was open sometime in the early 1990s.

For building any kind of loop in west Austin, I think the window of opportunity closed a long time ago. The only possible option is to upgrade RR620, and I don't think the long term regional plan calls for much improvement to 620, so I don't think much will ever happen.

On a more positive note, TxDOT is moving forward with plans to remove all traffic signals on Loop 360. In Austin, that's a major victory.

Does that include the section between Mopac and 290/Lamar? If so, that would create a loop with 183 being completed on the east side. Only thing needed would be direct connectors at 360 and 183, which there looks to be some ROW there for it.

To answer your question: the improvement program does not appear to include the section between Loop 1 and US 290 on the south end. There is one traffic signal in that section for northbound only.

The project also appears to not include any improvements at the Loop 360/US 183 on the north end, and at the Loop 360/Loop 1 intersection at the south end. I agree that direct connectors are needed, because those two intersections will likely become huge traffic bottlenecks when all the traffic signals on Loop 360 are removed.

Houston is located near lots of water (bayous and the Gulf of Mexico), and that didn't stop them from building two full loops (I-610, Beltway 8) and a 3/4-loop (TX 99).

Go back and reread the post.  Houston is about as flat as it gets whereas Austin has a very hilly terrain on the western side plus Lake Travis.  Also, Houston has planned for the "wheel and spoke" freeway design since the 50's. And, as mentioned above, the civic mindsets are quite different.

Also, the center of Houston is about 30 miles (give or take) from coastline, which is plenty of room for loops.
