Tesla marked the start of high-volume Semi production at its new Sparks, Nevada factory on September 24. The plant, which Tesla says covers 1.8 million square feet, is built to scale to 50,000 trucks annually.

Rewrote pre-event present/future copy (“is hosting today”, “will see”, “plans to detail”) to past tense after the Sep 24 Semi Rollout completed; kept 1.8M sq ft figure.
Wrong: title, summary and body gave the Sparks Semi plant as 1.7 million square feet, a figure from earlier secondhand reporting (NotaTeslaApp). Right: Tesla said during the Sept. 24 rollout broadcast that the plant covers 1.8 million square feet (@tesla_semi, 2026-09-24); figure now attributed to Tesla.
The company is celebrating the dedicated Semi plant, which Tesla says covers 1.8 million square feet and is now online and designed to reach 50,000 trucks per year.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
