Waymo has quietly snapped up a desert-scale proving grounds in the far northwest Valley, adding roughly 5,458 acres of private roadways, tracks and simulated city streets to its testing portfolio. The reported $220 million acquisition hands the robotaxi company a sprawling campus with a high-speed oval, dedicated freeway stretches and an urban course that can be used to rehearse rider-only operations away from public lanes. The buy deepens Waymo’s footprint in metro Phoenix as it ramps up vehicle production and commercial deployments.
As reported by ABC15 Arizona, which republishes reporting from the Phoenix Business Journal, the property sits around 211th Avenue and Dove Valley Road in the City of Surprise and borders the unincorporated community of Wittmann. That reporting says the sale closed on June 5 and that Waymo paid $220 million for about 5,458 acres. Local coverage notes the site was once used by Chrysler for hot-weather testing and was later rented and purchased by Apple for Project Titan work.
What’s on the grounds
Reporting in TechCrunch describes the complex as containing a roughly 115-acre simulated city course, a 35-acre vehicle-dynamics area, a four-mile banked oval and dedicated freeway sections built for autonomous testing. A Waymo spokesperson told TechCrunch the company will use the facility to simulate driving scenarios in a controlled environment and to support rider-only testing, motion-control work and operational training workflows.
County records back the deal
Maricopa County’s recorder database lists a recorded document for the transaction dated June 5 and provides filing details for the transfer. The county pages indicate the grantor and grantee names tied to the sale, consistent with publicly filed documents for the property.
Why Waymo bought it
The scale and diversity of the site give Waymo a repeatable environment to accelerate testing cycles and refine rider-only operations without putting extra miles on public streets. The purchase dovetails with Waymo’s local manufacturing and integration push, with vehicles being outfitted for service at an Arizona integration plant operated with manufacturing partners, a project detailed in industry reporting that positions Mesa as the company’s integration hub for vehicles headed to Valley service.
Local context and next steps
When reached for comment, Waymo confirmed the sale but declined to provide detailed operational timelines at the time of reporting, according to local coverage. The acquisition joins other recent Valley moves, including a Tempe office and the Mesa integration plant, that have drawn both praise for potential local jobs and renewed questions about safety oversight, as Tempe tower office move coverage and other outlets have noted.
For now, county filings and permit activity will be the clearest indicators of when the site transitions from quiet tracks to active training for Waymo’s growing fleet. The transfer is a tangible sign that the Phoenix region remains a national center for autonomous-vehicle testing, manufacturing and deployment.
