Elon Musk said on Sept. 20, 2026, that The Boring Company is working on an Austin–San Antonio tunnel he claims could carry passengers above 200 mph and cut the trip to under 30 minutes. No route, funding or construction timeline has been disclosed.
The Boring Company said it would be “excited and honored” to build the project. It described an express service with no intermediate stops, linking an Austin parking lot to a San Antonio destination if stations were available at both ends.
The proposal also leaves station locations, the tunnel alignment, construction costs, vehicle design and government partners unspecified. The article characterizes it as a company objective, not an active infrastructure build; permits and physical construction had not been publicly identified in the reporting it reviewed.
