The Boring Company (TBC) is an American construction and equipment startup founded by Elon Musk. Its name is a deliberate pun, with “boring” meaning the act of tunneling underground rather than dull or drab. The company aims to do away with urban congestion by enabling high-speed, point-to-point travel networks beneath city streets.
What Does the Boring Company Do?
The Boring Company builds underground tunnels for high-speed transportation, as well as its own tunneling machines. The company’s goal is to reduce traffic congestion by shuttling people through these tunnels in autonomous electric vehicles.
Musk started The Boring Company in 2017 after venting about Los Angeles traffic on Twitter. “Traffic is driving me nuts,” he wrote. “Am going to build a tunnel boring machine and just start digging…” And, unlike some of the tech mogul’s other more whimsical ideas — like launching a candy company or building a cyborg dragon — this one actually stuck.
Today, The Boring Company is valued at nearly $6 billion and has completed two projects — one of which, the Las Vegas Convention Center Loop, is open to the public. The company is currently seeking regulatory approval for a similar system in Nashville and beneath LA’s Dodger Stadium, and recently signed a contract for its first international project in Dubai.
What Is The Boring Company?
The Boring Company is a Texas-based startup that builds underground tunnel systems known as “Loops” to alleviate traffic congestion in big cities. Founded by Elon Musk, TBC started off as a subsidiary of SpaceX (Musk’s aerospace company), and then was spun off as a separate entity in 2018. Its ultimate vision includes high-seed, fully autonomous vehicles that shuttle passengers around on narrow, single-lane tracks under the earth. Current projects utilize modified Teslas at lower speeds.
In addition to fixed-route transit systems, The Boring Company also builds its own custom excavation equipment and handles its own tunnel construction. Its proprietary machines are designed to bore faster and more efficiently than conventional designs, enabling narrow, electric-vehicle-only tunnels and sub-surface stations that fit below existing above-ground infrastructure.
The Boring Company’s Core Technology
At the heart of The Boring Company’s operations is its tunneling technology. These massive, cylindrical machines — known as tunnel boring machines, or TBMs — slowly grind through soil and rock using a rotating cutterhead. As they advance, they simultaneously install precast concrete tunnel linings and remove debris along conveyor-belts, reducing the need for multiple work phases. Ultimately, the goal is to create a machine that operates continuously, minimizing the downtime typically needed for things like wall reinforcement or part replacements.
So far the company has developed three generations of TBMs: a standard model named Godot, followed by two custom-built machines, Line-storm and Prufrock. The latest iteration, Prufrock, is designed to tunnel at a speed of one mile per week, which is six times faster than its predecessor. Although this is still four to five times slower than a garden snail, according to the company, the hope is that this technology could one day be used to dig infrastructure on Mars as well as Earth.
Another key part of The Boring Company’s success is that it is a vertically integrated company. Because it designs and builds much of its own machinery in-house, it can iterate more quickly and maintain more control over costs, timelines and overall performance.
One of the biggest innovations The Boring Company has made thus far is its reduction of standard tunnel diameters (28ft), which it has managed to cut nearly in half. This smaller diameter size significantly lowers the amount of material that needs to be excavated, which in turn cuts overall construction costs. As a result, TBC claims its in-house technology can bore tunnels for as little as $10 million — a fraction of the $1 billion-dollar-per-mile price tag for conventional urban tunneling projects.
The Boring Company’s Key Projects and Pilots
The Boring Company portfolio includes a wide range of tunnel-based transit projects — and, for reasons known only to Musk, also features a flamethrower and a unisex fragrance. Below, we take a look at some of the company’s most talked-about ventures so far, from completed tunnels to scrapped ideas to projects that are still in the works.
Las Vegas Convention Center (LVCC) Loop
Status: Complete; Open to the public
Opened in June 2021, the LVCC Loop is The Boring Company’s first operational passenger tunnel system. It links three stations across the Las Vegas Convention Center via two 0.8-mile tunnels, where passengers are transported in human-driven Teslas. Designed to alleviate foot traffic during large events, the system is currently capable of transporting a peak capacity of 4,500 people per hour. The LVCC cuts a 45-minute cross-campus journey to about two minutes, according to the company’s website.
Hyperloop
Status: Under construction; Test track complete
Hyperloop is The Boring Company’s concept for an ultra-high-speed public transit system, designed to carry passengers in autonomous electric pods at more than 600 miles per hour. Unlike the slower, short-range Loop system, Hyperloop aims to connect distant cities via near-vacuum tunnels to dramatically cut travel times. According to TBC, a Hyperloop trip from Washington D.C. to New York would take less than 30 minutes, and a trip from D.C. to Baltimore would take less than 8 minutes.
A 0.8-mile test tunnel — known as the Hypertube — was completed in 2016 and has hosted multiple student competitions, with prototype pods reaching speeds up to 288 mph. Though the test track is complete, the project remains in development as the company continues to work with city governments and private partners to assess the technology’s feasibility in real-world settings.
Vegas Loop
Status: Under construction
The Vegas Loop is an add-on to the LVCC Loop that connects high-traffic destinations like the Strip, Harry Reid International Airport, Allegiant Stadium and downtown Las Vegas. Approved for up to 68 miles of tunnels and more than 100 stations, the Vegas Loop is being built in stages, gradually expanding as it gains support from local stakeholders like casinos and hotels. Several sections are already under construction, and once complete, the privately operated system aims to move more than 90,000 passengers per hour — offering fast, traffic-free rides separate from the city’s public transit network.
R&D Tunnel
Status: Complete
Now defunct, this 1.14-mile tunnel beneath Hawthorne, California operated as a testing ground for tunneling methods and early versions of the Loop and Hyperloop systems. Completed in 2018, it began at the SpaceX headquarters and featured a 12-foot internal diameter, as well as three stops — one of which was the small surface-level O’Leary Station. With testing now wrapped, the tunnel has since been decommissioned and paved over for parking. Although the R&D tunnel was never meant for public use, it served as a proof of concept and helped shape future projects like the LVCC and Vegas Loops.
Cybertunnel
Status: Complete; Operational
Located at Tesla’s Gigafactory in Austin, Texas, the Cybertunnel is an underground passage used to transport finalized Cybertrucks directly from the end of the production line to a final staging area located on the other side of an 8-lane highway — taking what was a 12-minute journey on standard roads down to 60 seconds, according to the company. The tunnel was built using The Boring Company’s new Prufrock-3 machines, which are designed for minimal surface disruption and faster deployment. Tesla briefly paused Cybertruck production during the Cybertunnel’s construction in in June 2024, but it is now fully operational and integrated into the factory’s production flow.
Dubai Loop
Status: Pre-construction
In February 2025, The Boring Company secured a contract to construct a 17-kilometer underground loop system in Dubai, marking its first international project. In alignment with smart city initiatives, the loop will feature 11 stations, transporting 20,000 passengers per hour at 100-mph speeds. The project remains in the early planning phase, so details around timelines, funding and regulatory approvals are yet to be finalized.
Music City Loop
Status: Pre-construction
The Music City Loop is a 10-mile tunnel The Boring Company plans to build in Nashville, connecting downtown to the city’s international airport. Supported by Tennessee state officials, the loop is being billed as “entirely privately funded” and “the safest, most efficient travel system in America.” While construction could begin as early as spring 2026, the project remains in the early stages of pre-construction, with key details surrounding permitting, geological risks and long-term public-private agreements still in the works.
How Does The Boring Company’s Loop System Work?
The Loop is an underground, all-electric transportation system designed to move passengers through tunnels using electric vehicles — primarily modified Teslas, which (for now) are driven by humans. Passengers enter a station, and board a Tesla, which is then lowered to a single-lane tunnel. From there, the vehicle travels directly to the destination under funky, disco lighting.
This is different from the Hyperloop concept, which envisions high-speed travel in near-vacuum tubes reaching speeds over 600 mph. The Loop operates at more moderate speeds — around 35-40 mph — in standard-pressure tunnels. It’s meant for short-distance, last-mile trips rather than intercity travel.
The Loop aims to go beyond traditional subway systems, offering a faster, more personalized experience. Unlike subways, which run on fixed steel rails with scheduled stops at designated stations, the Loop uses individual EVs that travel along guided pathways, providing direct, point-to-point service with no intermediate stops or alternate routes. While both systems help reduce emissions and ease above-ground traffic congestion, the Loop aims to combine the convenience of a personal car experience with the accessibility and efficiency of public transit.
Questions Surrounding The Boring Company
Many transit experts question The Boring Company’s approach altogether. Simply put: Individual cars transporting parties one at a time simply can’t match the capacity of conventional subways or light rail, so why bother?
A 2020 report from The Verge found that, despite claims of moving thousands of passengers in Las Vegas, the Loop’s throughput is significantly lower than mass transit alternatives — and may even have to be, according to fire regulations. As one critic put it, “Tunnels full of cars are not feasible … cars in tunnels will never be able to transport as many people as a subway train.”
Questions have also surfaced regarding the company’s use of public contracts and oversight. The Las Vegas Convention Center Loop received nearly $48.7 million in public funds, but, as a privately operated project, it is exempt from standard safeguards — like open bidding, transit-agency review and several environmental checks — that are typically required for public transit projects. In Los Angeles, a proposed Sepulveda tunnel was canceled after neighbors sued, alleging the project dodged environmental impact analysis.
And to be fair, The Boring Company doesn’t have the best track record on the regulatory front, having been cited for multiple environmental and safety violations. For example, Nevada regulators fined the company more than $112,000 following incidents of chemical burns, tunnel flooding and untreated wastewater discharge. In Texas, work began near Bastrop without proper erosion controls or permits, adding an additional $11,800 to its tab of regulatory fines and spurring local outcry.
The Boring Company’s Future Outlook and Expansion Plans
The Boring Company has an ambitious growth roadmap, with potential projects underway all over the world, but primarily in the United States. In Nashville, the company is planning to construct a 10-mile tunnel called the Music City Loop that will connect the city’s downtown area to its international airport. And after being pushed out of West Los Angeles, the company is now focused on building underground transit solutions around Dodger Stadium. Of course, all of these projects hinge on the company’s ability to navigate local regulations.
To support these expansions, The Boring Company is continuing to develop more advanced tunneling technology. Its latest, Prufrock-3 (nicknamed “The Monster”) is designed to dig tunnels without any site preparation. Even newer versions, Prufrock 4 and 5, are reportedly even better, but they have not yet been deployed. Another notable advancement is the company’s Zero-People-in-Tunnel technique, which enables continuous tunneling operations without any human presence inside the machine.
Elon Musk’s extracurricular involvement in U.S. politics may also influence The Boring Company’s future. His brief stint at the helm of the Department of Government Efficiency, or DOGE, and (now strained) relationship with President Donald Trump likely eased access to previous regulatory approval hurdles, and may have helped put the company in the running for big-ticket engineering contracts — most notably a multi-billion-dollar Amtrak project that will connect Baltimore to Washington D.C. and Virginia.
Major Milestones for The Boring Company
Since its founding in 2016, The Boring Company has worked to reimagine urban transportation with its low-cost, high-speed tunnel systems. From early prototypes to major commercial projects, the timeline below charts some of the company’s most notable developments.
Work on Las Vegas Airport Tunnel Suspended After ‘Crushing Injury’ (September 2025)
The Boring Company has paused work on its Vegas Loop tunnel to Harry Reid International Airport after a worker suffered a “crushing injury.” It is unclear what exactly happened to the worker, but reports say fire crews had to lift the person out of the site using a crane — though officials now say the worker is “reported to be stable.” Nevada’s Occupational Safety and Health Administration has opened an investigation into the matter.
This incident adds to a string of reported injuries during the construction of Boring Company tunnels. Even the company’s former safety manager has publicly voiced concerns about the dangers of working on these sites.
Music City Loop Announced (July 2025)
Both The Boring Company and Tennessee Governor Bill Lee announced plans to build the Music City Loop, a 10-mile tunnel connecting downtown Nashville to its airport. The governor’s office says the plan will be “entirely privately funded” and called it “the safest, most efficient travel system in America.” Still, the project has received some pushback from city officials citing environmental impact and public oversight concerns. The Boring Company says the first segment of the loop could be operational as soon as Spring 2026.
Vegas Loop Expanded (May 2025)
After resolving various fire-code and permitting delays, The Boring Company began accelerating its Vegas Loop expansion, with new tunnels and stations around the resort corridor and downtown. The full build-our will include 104 stations and 68 miles of tunnel, according to Steve Hill, Las Vegas Convention and Visitors Authority president and CEO.
Dubai Loop MoU Signed (February 2025)
The Boring Company signed a memorandum of understanding (MoU) with Dubai’s Roads & Transportation Authority to pilot the Dubai Loop, a 17-kilometer tunnel network that will shuttle as many as 100,000 passengers to 11 stations throughout the city at speeds of up to 160km/hour. MoUs are not legally binding, and are instead meant to outline the objectives of a future partnership with the intention of committing to a more formal contract later on. No formal timeline on this project has been disclosed yet.
Prufrock-3 Debuted at Giga Texas (June 2024)
The Boring Company used its new Prufrock-3 machine to dig a tunnel at Tesla’s Gigafactory in Austin, Texas. Dubbed the Cybertunnel, the underground passage is used to shuttle finished Cybertrucks from the end of the production line to the factory’s outbound lot. According to the Boring Company, Prufrock-3 “porpoised” out of the ground onto a large retrieval structure called “The Monster” inside the already-constructed factory, then exited the building on a self-propelled modular transporter (SPMT).
The Alamo Loop Approved (March 2022)
The Alamo Regional Mobility Authority (RMA) selected The Boring company to construct a loop system connecting the San Antonio International Airport to the city’s downtown area. Called the Alamo Loop, the total estimated cost for the project was between $247 and $289 million — $27 million to $45 million of which would be covered by The Boring company — and total revenue to the RMA was expected to come to $25 million a year. The project appears to be at a standstill, however, as The Boring Company “ghosted” the RMA, according to officials. The company has done something similar in cities like San Bernardino and Chicago.
Vegas Convention Center Loop Opened (June 2021)
The Las Vegas Convention Center Loop is the first Boring Company project to open to the public — and remains its only publicly accessible tunnel to this day. The 1.7-mile loop system transports riders in human-driven Teslas between the convention center’s exhibition halls, and continues to be expanded around the city.
The Boring Company Founded (December 2016)
Musk founded The Boring Company in December 2016 after expressing frustration with urban traffic congestion. It began as a subsidiary under Musk’s aerospace company SpaceX, then spun out into an independent entity in 2018.
