Giga Texas Is Growing Fast: North Campus Expands North, Southwest Test Track Takes Shape

Tesla's Giga Texas campus in Austin never really stops moving — but this week's drone flyover from longtime aerial observer Joe Tegtmeyer captures two developments that deserve a closer look. The North Campus construction footprint is expanding further northward, and the Southwest Test Track is no longer just a cleared patch of land: road surface grading and geotextile membrane application are now visible from the air.

North Campus: Optimus Is Getting Its Factory

The North Campus expansion is the most consequential construction project at Giga Texas right now — and possibly on the planet, if Tesla's production ambitions for Optimus are taken at face value. According to work permits filed with the Texas Department of Licensing and Regulation in November 2024, Tesla plans to add over 5.2 million square feet to Giga Texas by the end of 2026, bringing the total campus to approximately 15 million square feet.

The North Campus is specifically designated as the production and support hub for Optimus. Site prep work is extensive: crews are clearing land, reclaiming soil, and hauling in infill dirt to level out what were formerly sand and gravel mine areas. Geopiers and geotextile membranes — the same materials now visible at the test track — are being used to stabilize the ground before any structural work begins. Major structural work is expected to wrap by late 2026, with equipment installation following. Initial Optimus production is projected to begin in 2027.

Tesla's stated production ambition is 10 million Optimus units per year — a number that sounds staggering but explains the sheer scale of what's being built here. The North Campus pushing further north, as captured in today's flyover, is a direct signal that the timeline is moving forward.

Southwest Test Track: Cybercab Validation in Progress

The Southwest Test Track is a newer addition to the Giga Texas story, and it's developing quickly. What Tegtmeyer captured today — road surface grading and geotextile membrane application — is consistent with ground stabilization work that precedes paving. Earlier observations from March 9 noted that an oval shape appears to be emerging on the west side of the track area, suggesting a defined circuit layout rather than a simple straight-line test strip.

Crews have also been removing conduit risers and filling drainage ditches to level the grade — detail work that points toward a track surface that's closer than it might appear from the air. The intended purpose of this facility is Cybercab validation and future vehicle development testing, keeping that work on-site rather than relying on external proving grounds.

The timing aligns with Cybercab production activity on campus. More than 30 Cybercabs were spotted across the Giga Texas site as recently as March 9, including units on transport trucks and at the crash testing facility. The first production Cybercab rolled off the Giga Texas line in mid-February 2026 — ahead of the anticipated April start for mass production. A dedicated on-site test track would give Tesla's validation teams a permanent, controlled environment to accelerate that program.

River Road and Campus Access

Today's flyover also referenced the River Road area. New permits detail a River Road extension designed to improve access around the east and south sections of the campus, connecting to Harold Green Road and State Highway 130. Work in the far northeast involves removing hills and ponds, correcting grade, and clearing tree debris — the kind of infrastructure investment that only makes sense if you're planning for a campus that will eventually host tens of thousands of workers and daily logistics operations at scale.

🔭 The BASENOR Take

What today's flyover really tells us is that Giga Texas is no longer just a car factory. The North Campus expansion and the Southwest Test Track represent two entirely different product lines — a humanoid robot and an autonomous vehicle — being built simultaneously on the same campus. The geotextile membranes and grading work might look like routine construction from the air, but they're the foundation for what Tesla is betting will be its two largest revenue drivers of the next decade.

For Tesla owners watching the Cybercab rollout, the test track development is particularly relevant. On-site validation infrastructure typically shortens the gap between production start and customer delivery — Tesla doesn't have to ship vehicles to a remote proving ground and back. With 30+ Cybercabs already moving around campus and a dedicated test circuit taking shape in the southwest corner, the validation pipeline is being built in parallel with production. That's an efficient setup, and it suggests the April mass production target is being taken seriously at the infrastructure level.

The Optimus story is longer-dated but no less significant. A 15-million-square-foot campus purpose-built around humanoid robot production would be unlike anything that exists in manufacturing today. The North Campus expansion pushing further north — visible in today's drone footage — is a physical commitment to that vision, one concrete pour at a time.
