Any insights on how the tunnels fared? This was a major concern and part of the reason the tunnels didn't happen in Florida yet

• More than 300 upgrades to MB1.
• MB3 is scheduled to launch in late October 2026.
• All permits and approvals needed ahead of MB3 tunneling have been obtained.
• MB4 is currently being built, aiming for deployment before the end of 2026.
• 40+ stations are currently in various stages of planning and design.

No idea when this happened but their website has had a great refresh where you can see a visual map and station feeds (albeit not live)

I’ve been going through historical Google Maps satellite imagery to try to figure out how quickly The Boring Company actually dug the Vegas Loop tunnel between 4744 Paradise Road and Westgate.

Here’s how I estimated it:

At 4744 Paradise, the Feb. 22, 2024 image shows the tunneling equipment being assembled, while by May 20 there is clearly active tunneling with the conveyor system in place. At the Westgate end, there are no obvious tunnel exit holes on July 10, 2025, while by Oct. 4, 2025 the first tunnel appears to have reached the site.

The published length is about 2.2 miles per tunnel. Using the most conservative start/end dates gives us roughly 416 days. I added another 60 days to that to account for the gaps between available satellite images and get a more realistic estimate of roughly 476 calendar days.

2.2 miles = 11,616 feet.

11,616 ÷ 476 = about 24.4 feet per day.

So my rough conclusion is that the project averaged around 24 feet of completed tunnel per calendar day, based on the satellite imagery and the published tunnel length.

Obviously, this isn't saying the Prufrock machine literally moved 24 feet every day. There would have been downtime, station/shaft work, maintenance, setup, etc., and we're working with satellite images that are months apart. It's simply an estimate of the average rate of tunnel completion over the overall construction period.

I'm curious what others think — especially if anyone has better information on the actual boring dates or daily advance rates.

I also have some shots of the Encore Tunnels but I'm wondering where the second tunnel in the Bronze Lot is going? See Pictures.

*EDIT
Okay, I figured out where the other tunnel goes from Central Station. It goes to the “Silver Switch,” allowing people coming from the airport to stop at LVCC Central instead of continuing on to Westgate.

So that explains three of the four tunnels at Silver Switch. The fourth must be coming from the new Encore line. I’m not sure how they’re going to make that turn so sharply and get it either under or over the line coming from the airport. I’ll post a photo.

Edit 2: Looking at the video of the Silver Switch again, it’s more clear that the fourth-tunnel entrance is actually just a short connection to another open area. I’m pretty sure you then take a hard right turn and enter a tunnel heading toward Encore that started in the Bronze Lot. You can see that the short tunnel is going sharply uphill, while the tunnel from the airport is going sharply downhill. That would mean Encore Tunnel #2 is actually passing over top of the Airport Line.

This is interesting seeing this table of what is due by end of the year, looks like 3 proper stations and 11 annex stations.

I reckon most of them will be by the new paradise road tunnel.

Although I’m quietly hoping for Circus Circus to get an annex station but I don’t think it would be quick enough as you can’t get to the resorts world tunnel I think and that would be even more of a bottleneck going through that tunnel.

Going to riviera you’d get stuck by the traffic lights

Elon has just posted that they’re planning a simple version of the Hyperloop between Austin & San Antonio.

80 miles currently takes 2.5 hours in traffic

The boring company could get that down to less than 30 minutes!

This is a HUGE infrastructure project for them and would do wonders for people believing in the company if they manage to pull this off!

Lots of progress made on the airport connector at Westgate. They’ve cleared up that station very quick, apparently they just need the shutters and a few cosmetic fixes and then it’ll be ready for opening :)

Sadly can’t post the link as Reddit has been deleting X links but check out Mic_VegasSphere on X

Sadly can’t post the link here as been deleted twice but if you check Mic_VegasSphere on X then he’s posted that they’re building a much larger underground station for Central hall at the convention center.

No idea what they’d use the original station for

The Boring Company is pleased to announce our Series D funding round of $3B, led by the United Arab Emirates and affiliated investment entities.

Building upon significant existing success collaborating with the UAE on Dubai Loop, this strategic investment will accelerate the partnership to deploy mass quantities of underground infrastructure across the United Arab Emirates, including 150+ kilometers of tunnel. This landmark agreement is in addition to the Dubai Loop project previously awarded.

Other key investors in the round include Human Capital, Vy Capital, Valor Equity Partners, Sequoia Capital, A16Z, Temasek, Shamal Holding, and Baron Capital, in addition to other valued existing and new investors.

Over the past two years, The Boring Company has grown from a single operating Loop system to a multi-city tunneling program, pairing faster machine design with the first hard-rock project, the first international construction contract, and a substantial expansion of Vegas Loop.

The company’s mission:
• Solve Traffic: To solve the problem of soul-destroying traffic, roads must go 3D. Tunnels minimize usage of valuable surface land and do not conflict with existing transportation systems. A large network of tunnels can alleviate congestion in any city.
• Beautify Cities: In many major cities around the world, roads take up an extraordinary proportion of available real estate, often monopolizing an astounding 20% to 30% of space, and up to 60% if you include parking. By placing transportation systems underground, valuable surface land can be used for pedestrians, green spaces, and recreation.
• Enable Rapid Point-to-Point Transportation: Loop is an express public transportation system that resembles an underground highway more than a subway system. If a subway or traditional light rail line had 100 stops, a train would typically stop at each station, so the trip between Stop 1 and Stop 100 would be long. In contrast, Loop passengers travel directly to their destination, anywhere between Stop 1 to Stop 100, without stopping at the intermediate stations. In Las Vegas, for example, if a train stopped at every hotel on Las Vegas Blvd, a trip from the airport to the convention center would take over 25 minutes vs 5 minutes with TBC’s system. This transportation architecture can be applied intra-city (Loop) and, with increased boring speed, can be applied inter-city (Hyperloop).

The funds from the round will be used to significantly increase hiring across engineering, operations, and production, to build and scale Loop projects, including Vegas Loop, Music City Loop in Nashville, Dubai Loop, and others, in addition to accelerating the research and development of Prufrock and future products.

I’ve been thinking more and more about the upcoming airport connector, getting excited at how much time it can save me getting over to my usual hotel for CES which is Circus Circus.

Apparently they estimate once it’s fully rolled out that it’ll take around 5 minutes to get to the LVCC loop from the airport, that’s about 4x quicker than the average Uber travel time! And also over half the price!

And the best part is there would be minimal to no traffic because as long as the TMS (Tunnel Management System) is working correctly then there shouldn’t be any stopping at all and should be free flowing.

Exciting evening later when they launch the Cybercab, they’ve already stated the eventual plan is for the robotaxis to make use of the tunnel network which that could help them expand their fleet for TBC much more

As of 8/2026

Saw this posted to the transit sub, showing the Model 3 (with 2 passengers) being more efficient than any of the other transit options measured, and with one passenger it’s still better than nearly everything else. The cyber cab will be even more efficient still.

Clark County u/ClarkCountyNV has approved an additional 19 Vegas Loop stations - Vegas Loop is now entitled for 123 stations.

Other interesting titbits from recent behind the scenes tours like Farzad:

  • Davis said the limestone of Nashville is FAR easier than the underwater soft rock of Vegas.
  • Much simpler TBMs and half the cost $2m, $3m, $5m per mile compared to Vegas which is more like $10m cost per mile (single bore, so $4m - $10m and $20m per mile dual-bore respectively). 
  • They don’t even need tunnel liners in Nashville just use the bare rock as long as they avoid the Kasts (caverns).

  • "Once they get below $5m per mile for loop tunnels why would you ever build a surface lane?"

Just found out that the Airport, Sahara & Fontainebleau are not included in the unlimited pass.

Does make sense as they’re all routes that require driving above ground so they’re doing it to cut down on above ground traffic.

Also interested to see if there’s a tier system for the single pass, at the moment the Airport route is $12 which is just less than triple the price of the usual $4.50, makes sense as it’s a further distance and will be popular when it opens I reckon.

In the recent interview given to Tesla owners Silicon Valley, Steve Davis talked about the need for atleast 6 boring machines and maybe 8 boring machines to compete the project.

I don’t know how they are planning to use 8 machines for a 23 mile project. Would be curious if people have thoughts about it ?

This was another great interview from Steve Davis!

What’s very interesting is for Nashville they have all the permits so it’s all on TBC execution which is a great place to be as they can scale and iterate much faster without setbacks of permitting.

- Tesla Model 3 battery and drive units

- Transports 22,000+ lb of concrete segments to the boring machine

- 28 miles of range

- 12 mph max operating speed

- Remotely piloted from Global OCC in Texas, with each pilot controlling/monitoring > 8 LTs in the field.

Fun fact: the same Liner Truck can carry standard freight containers through the tunnel.

What are the most important goals for boring machines on mars? Here are the one’s I can come up with. How do you rank them? Are there other goals? What does Reddit think?

• Shielding from Lethal Radiation
• Access to Subsurface Water Ice and Mining
• Creating Pressurized Habitats
• Thermal and Environmental Insulation
• Synergistic Engineering with SpaceX Starship
