Vegas Loop isn’t just tunnels! In Vegas, besides 14 tunnels, TBC has built 14 stations (28 by end of year), 12 emergency egresses, 6 cross-passages, and 9 "knockout shafts".
See below for the construction of a cross-passage connecting "Tunnel-1" and "Tunnel-2" (beneath Paradise Road) to provide access and egress; construction time is ~10 days.
Steps:
1. If necessary, treat the ground (typically with grout) between the two tunnels such that it is stable during excavation.
2. Brace the Tunnel-1 wall with a steel frame and open up the concrete Tunnel-1 wall within said frame.
3. Excavate the dirt between the tunnels, installing steel ribs and wood lagging to maintain a safe roof until Tunnel-2 is exposed. This is a slow process of 10 feet per day.
4. Install waterproofing and rebar, the latter which anchors into both Tunnels 1 and 2 (see pic)
5. Install solid steel liner plate (see pic)
6. Pour high-strength concrete around the liner plate, reinforced with the rebar from Step 4
7. Open up Tunnel-2, finalizing the connection
Finally, the cross-passage is built out with a walking surface, ventilation, fire suppression valves, fire-rated doors, safety equipment/sensors, lighting, and cameras.
Vegas Loop isn’t just tunnels! It is also stations, merge/exit ramps, cross-passages, ventilation chambers, and emergency egress shafts.
See pics for the construction of an egress shaft; construction time is ~8 days. Steps:
1. Excavate down to expose the tunnel exterior
2. Install waterproofing, conduit, and rebar, followed by pouring a concrete base slab adjacent to the tunnel
3. Add steel-reinforced concrete walls and backfill the perimeter
4. Pour a concrete roof (leaving an opening for egress) and pave over the structure with asphalt; final surface impact is ~120 square feet
Once the structure is complete, a doorway is cut into the tunnel to connect the tunnel to the shaft. Finally, the shaft is built out with stairs, ventilation, standpipe, safety equipment/sensors, access hatch, lighting, and cameras.

UPDATE BORING COMPANY VEGAS LOOP
Ok this is bizarre. I get home from a trip to LA and THIS has been installed in our lobby. It’s a Boring Loop terminal for calling for a car directly to where I live.
I assume it would take me into the tunnel at Westgate or Riviera. It means I now have door to door service to the Convention Center or Encore or the Airport. When the Loop is connected to A’s stadium or Allegiant, it would be a non-stop door to door pick up and delivery that’s fast and cheap compared to other services.
Crazy! After covering the Loop progress for years they gave me a little present.

I will not pretend that it has not been a tough two weeks. Damien and I tried to finally take a holiday together and it was totally hijacked when three councillors in an incorrect use of the legislation tried to call a council meeting to vote to kill -#SummerInTheCity. 1/2

If you where the @EIB would you lend @GovIE @DarraghOBrienTD @Dept_Transport @TIITraffic @IrishRail & NTA for #Metrolink? for God knows how much it will end up costing for something that will be woefully, outdated, primitive & completely DraghiReport ignored! – at Dublin City, Ireland

More than €350 million has already been spent on MetroLink, with transport officials warning the project could exceed its original €7–€12 billion cost estimate.
Appearing before the Oireachtas Infrastructure Committee today, transport executives gave few firm answers, including on whether more than €80 million was paid to acquire the former Carlton Cinema site on O'Connell Street for the project.

Precast concrete operation at TBC Dubai. The first phase of Dubai Loop will utilize ~25,000 segments, each weighing ~4,000 pounds. Total tunnel weight: ~100 million pounds!

Tunneling on a Wednesday night in Nashville.
Great rock. And a winning smile.

AMERICA IS BUILDING AGAIN 🇺🇸
I went underground with @boringcompany checking out the MUSIC CITY LOOP — a massive 25-mile twin-tunnel system in Nashville that will move people from the airport to downtown with ZERO traffic
@USDOT processed approval requests within 1 MONTH — that’s 6X FASTER THAN NORMAL
Even better — the project used ZERO TAXPAYER DOLLARS
This is the kind of innovation that is powering the next revolution in transportation

Today, the Clark County Fire Department and The Boring Company Tunnel Rescue Team completed a rigorous hands-on technical rescue exercise inside a Vegas Loop tunnel.
These joint trainings help ensure first responders are prepared, coordinated, and ready to respond in any scenario.
TBC has hosted trainings for more than 200 firefighters and first responders with more than 150 hours of in-tunnel drills.
Thank you to CCFD for the continued collaboration and partnership in keeping safety as top priority in Vegas Loop.

See how Prufrock continuously mines - pushing and building at the same time.
The machines, from Las Vegas to Dubai, are remotely controlled from our Bastrop Operations Center.
These advances help TBC deliver more miles each year in the battle against soul-destroying traffic.

That's why I'd prefer to put them underground!
