Elon Musk’s Boring Company becomes frontrunner for Ontario Airport high-speed tunnel
It appears that Elon Musk’s tunneling startup, The Boring Company, is poised to secure a high-profile contract to build the Ontario Airport Loop, a high-speed transport tunnel connecting Rancho Cucamonga with the Ontario International Airport. The Boring Company’s tunnel will be a faster and more cost-effective alternative to above ground rail projects, which were previously proposed for the route.
The new Boring Co. project has received widespread support from the San Bernardino County Transportation Authority’s Board of Directors, who voted unanimously in favor of the system. As noted by The Mercury News, the Board of Directors also directed staff to postpone a $3 million study that explores other airport-rail connection options.
According to San Bernardino County Supervisor Curt Hagman, the Boring Company’s transport tunnels are a great, affordable alternative to more traditional rail systems, which take far longer to construct. Hagman was actually able to see the Boring Company’s technology in person, having visited the startup’s Hawthorne site and taken a test ride through the test tunnel.
“It gets us thinking in a new way. This is something that can be done relatively quickly and inexpensively,” he said.
The Boring Company’s Rancho Cucamonga-Ontario Airport tunnel will be 2.8 miles long. The tunnels themselves will be 14 feet in diameter and about 35 feet underground. For now, the proposal involves using electric vehicles with rubber tires traveling up to 127 mph from point to point, though plans are reportedly also underway to introduce electric vans for the transport system.
These electric vans are capable of seating up to 12 people and their luggage. The vehicles, which are being developed by Tesla, will boost the capacity of the system to about 1,200 per day, or over 10 million per year provided that they see a mass rollout. These electric vans seem very similar to the Boring Company’s mass transport units that were mentioned back when the startup was being considered for the Chicago Airport transport line.
The Ontario Airport Loop is expected to cost between $45-$60 million, though the project’s entire cost could reach about $75 million when the price of adding an operations center, management services, and operators’ wages is added. Yet despite this, $75 million is still a far cry from the estimated $1-$1.5 billion light rail extension that was also being considered.
The Boring Company’s Ontario Airport Loop is expected to be completed in about four years, far quicker than the 10 years that the construction of a light rail extension requires. Carrie Schindler, SBCTA director of transit and rail, explained this in a statement to local news outlets. “It is much more cost-effective. I do anticipate the need for outside funding but at a reduced level as compared to building surface projects,” the transit and rail director said.
The Boring Company may have only been around for a few years, but the tunneling startup seems to be hitting its stride with its projects. Prior to the Ontario Airport Loop, the Boring Co. has been contracted to build a Loop system for the Las Vegas Convention Center, which would allow visitors to the expansive site to travel from one end of the complex to the other in just a few minutes. The progress of the Las Vegas Loop has been quick, with the digging of both tunnels being completed recently.
A Tesla Semi was involved in a fatal collision on U.S. Highway 50 in Dayton, Nevada, on Sunday, June 28, 2026, marking the first known fatal crash involving the electric Class 8 truck. The incident occurred around 7:20 a.m. at the intersection with Traditions Parkway, approximately 40 miles east of Reno and close to Tesla’s Gigafactory Nevada.
According to the Lyon County Sheriff’s Office and the Nevada State Police Highway Patrol, a semi-truck struck two passenger vehicles stopped at a traffic signal. The truck hit the vehicles from behind. Two people were pronounced dead at the scene, and a third person suffered life-threatening injuries and was flown to a hospital, Forbes reported.
Preliminary statements gathered at the scene by the Lyon County Sheriff’s Office suggested the truck driver may have fallen asleep at the wheel. However, the Nevada Highway Patrol, which is leading the investigation, stated that the official cause has not yet been determined.
Additional information is expected to be released early the following week. The truck was seized for evidence as part of the ongoing probe.
Responders at the scene included deputies from the Lyon County Sheriff’s Office, personnel from the Nevada Highway Patrol, Central Lyon County Fire Department, and the Nevada Department of Transportation. The crash led to the temporary closure of U.S. 50 in both directions.
The Tesla Semi is Tesla’s battery-electric heavy-duty truck, produced at the nearby Gigafactory in Nevada. Authorities initially described the vehicle as a semi-truck; its make was subsequently confirmed through reporting and scene identification; an interesting bit of information here, as the Semi is not yet available publicly and many do not know that Tesla builds electric trucks.
The investigation remains active, with no further official details on contributing factors or vehicle systems released as of early July 2026.
This incident highlights ongoing scrutiny of commercial vehicle safety on Nevada highways, particularly involving fatigue. Law enforcement continues to gather evidence and witness statements.
Tesla has expanded its Robotaxi program to Miami, Florida, marking the third state the autonomous ride-hailing platform has made its way to since launching last Summer.
Tesla announced today that the Robotaxi suite would now officially launch rides in a geofence in Miami:

The first geofence in Miami covers approximately 10 to 14 square miles. The area appears to be focused on western and central Miami, including Miami International Airport (MIA). It also includes popular routes like SR 826 (Palmetto Expressway), US 41 (Tamiami Trail), and connectors such as SR 968, 953, 959, and 972.
This is Tesla’s initial Miami launch zone, smaller and more targeted than some competitors’ areas (for example, Waymo’s initial rollout was broader in eastern neighborhoods). It prioritizes high-traffic, airport-linked routes before wider expansion.
The expansion is a huge signal for Tesla that it is now operating in Florida, a heavy-traffic state with many tourist areas, including Fort Lauderdale, Palm Beach, and the Boynton area, all of which are coastal and will attract perhaps millions of tourists in any given year.

The Tesla Robotaxi network launched last year on June 22, in Austin, Texas, beginning limited commercial operations in that city. It expanded shortly thereafter into the San Francisco Bay Area of California in late July 2025, marking entry into a second state with service covering key areas such as San Francisco, San Jose, and Berkeley.
Full commercial service was achieved in Austin by November 18, 2025, strengthening its presence within Texas before further growth.
In 2026, the network continued expanding across Texas with the addition of Dallas and Houston on April 18, significantly broadening its footprint in the state. This new launch into Miami marks Tesla entering a new state and bringing active locations to include Austin, Dallas, Houston, San Antonio in Texas, and the Bay Area in California.
These sequential expansions have steadily increased the network’s reach across major metropolitan areas in Texas, California, and Florida, focusing on scaling operations city by city and state by state since the initial Austin debut.
Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.
Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.
Tesla Optimus project fires up as Musk sees production line progress
Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.
Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.
This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.
Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.
Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
