Giga Texas Gets a Test Track: What's Being Built at Tesla's Austin Campus Right Now

Giga Texas is in the middle of its most ambitious construction phase yet. Drone footage shot on the morning of March 5, 2026 — captured early to beat incoming high winds and rain — reveals three distinct major projects advancing simultaneously across the sprawling Austin site. The headline find: a new test track complex appears to be taking shape in the far southwest corner of the property.

Joe Tegtmeyer, who has documented Giga Texas construction more consistently than anyone, flagged the test track as a significant find — separate from the Optimus-related North Campus work that has dominated recent coverage. This is new territory, and it's been a long time coming.

📊 Key Figures

Three Projects, One Giant Buildout

The North Campus — Optimus Country

The North Campus is the most talked-about expansion at Giga Texas, and for good reason. Permits filed with the City of Austin point to this area becoming the production and support hub for Tesla's Optimus humanoid robot program. Site preparation is well underway — land clearing, soil reclamation, and plans to bring in infill dirt to level out old sand and gravel mine areas on the property. Geopiers and geotextile membranes are expected to be used to stabilize the ground for the scale of facilities planned. The stated production ambition is 10 million Optimus units per year, which would require an enormous amount of new floor space.

River Road Extension — Rethinking Site Access

The River Road extension is a less glamorous but equally important piece of the puzzle. New permits detail a road extension designed to improve access around the east and south sections of the campus, ultimately connecting to Harold Green Road and State Highway 130. The project includes drainage management systems and has required the relocation of equipment, workshops, and staging areas across the site. As Giga Texas grows in every direction, getting materials and vehicles in and out efficiently becomes a real operational challenge — this road work is the answer to that.

The Test Track — Finally

This is the find that stands out. Tegtmeyer notes the test track complex has been in planning flux for roughly 18 months, with the location changing multiple times before apparently settling on the far southwest corner of the site. Material staging yards that previously occupied the west side are being relocated to clear the way for new construction in that area.

It's worth being clear about what we know versus what's being interpreted: there is no official Tesla announcement about a test track at Giga Texas. What exists is expert observation — Tegtmeyer's consistent aerial documentation showing site preparation activity in the southwest corner consistent with track construction, combined with the relocation of staging infrastructure that previously occupied that space. The interpretation is credible, but it remains observation-based.

The drone footage also captured continued Cybercab activity on site, suggesting production-related work is progressing alongside the infrastructure buildout.

🔭 The BASENOR Take

📰 Deep Dive

Giga Texas was always designed to be more than a Model Y factory. The original vision for the site — sprawling across hundreds of acres along the Colorado River — anticipated growth that the initial production buildings only hinted at. What's becoming visible in early 2026 is that vision starting to materialize at scale, across multiple fronts at once.

The test track, if confirmed, would fill a notable gap in Tesla's Austin operations. Currently, vehicle validation and performance testing requires moving cars to other facilities. An on-site track eliminates that friction — and given the number of new vehicle programs (Cybercab, next-gen Model Y variants, Optimus mobility) that will need real-world testing, the timing makes sense. The southwest corner location also keeps the track away from the main production flow on the east side of the campus, which is a sensible layout choice.

The River Road extension is arguably the least exciting piece of this story but potentially the most consequential for day-to-day operations. As the campus grows north and south, a single access point becomes a bottleneck. Connecting to SH-130 via Harold Green Road gives Giga Texas the logistics spine it needs to handle the kind of throughput that Optimus production targets would demand. Infrastructure like this rarely makes headlines, but it's what separates an ambitious plan from one that actually executes.

Tegtmeyer's consistent documentation of this site over time provides a level of continuity that's hard to replicate. The fact that he flagged the test track as distinct from Optimus-related work — and noted its 18-month planning history — suggests this isn't a new idea suddenly appearing in aerial footage. It's a project that has been in motion behind the scenes, and the ground is now literally being prepared for it.
