The Boring Company’s Las Vegas Loop tunnel project is coming to life
The Boring Company’s upcoming Loop project at the Las Vegas Convention Center appears to be coming to life, with the first images of the startup’s dig site emerging online. Images that have emerged of the startup’s activities reveal that The Boring Company has started shipping parts of a tunnel boring machine to Las Vegas, with a TBM cutter head and mixing chamber recently arriving at the location.
Initial pictures of The Boring Company’s activities were shared on Twitter last week, courtesy of @JamesInLasVegas. The photos depicted heavy machinery surrounding the tunneling startup’s dig site, including several cranes and what appeared to be a pile driver. An image of a tunnel boring machine’s cutter head was also posted.

A source familiar with the Boring Company’s current activities for the Las Vegas Convention Center Loop project recently informed Teslarati that the startup’s activities have started ramping over the past few weeks. The source, who has asked to remain anonymous, added that The Boring Company has been granted a pit permit, and thus, the startup has started the construction of a secant wall for the Loop system’s passenger station located on the east end of the LVCC’s South Hall.
Similar to the initial Twitter posts that emerged of the ongoing project, the source also mentioned that parts of a tunnel boring machine started arriving Thursday night. First was what appeared to be a brand new cutter head, followed by a mixing chamber. Both these TBM parts were dropped off at a location that was visible from Desert Inn Blvd.
The Boring Company’s tunnel boring machine segments arrive at the Las Vegas site.
Interestingly, the secant wall is reportedly progressing quickly, and once this is done, excavation will soon follow. Overall, the Las Vegas Convention Center Loop appears to be progressing well, though hitting Elon Musk’s goal of completing the Loop system by the end of 2019 will likely remain a challenging task. But if the company’s digging technology is up for the challenge, the Tesla and SpaceX CEO’s timetable will likely prove feasible.
Much of the details about The Boring Company’s tunneling plans for the Las Vegas Loop system are yet to be announced. Perhaps the biggest question right now is if the startup will be deploying its next-generation TBM for the project. The Boring Company’s Hawthorne test tunnel was built using Godot, a conventional tunnel boring machine. Elon Musk has since announced that the startup is working on two new machines, a hybrid TBM named Line-Storm, which is capable of digging around twice as fast as Godot, and Prufrock, an all-electric TBM that can dig around 10-15 times faster than a conventional tunneling machine, with very little noise and zero emissions.

Images of what appeared to be a new TBM being assembled at the tunneling startup’s lot in the vicinity of the SpaceX headquarters in Hawthorne have been captured a few months ago. With this in mind, there seems to be a good chance that The Boring Company’s Las Vegas project could utilize one of the startup’s newer machines. Perhaps The Boring Company will play it safe and deploy Godot, which has already been tried and tested at Hawthorne, or perhaps the startup could utilize Line-Storm or Prufrock to complete the project faster.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
