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.
The Boring Company is pleased to announce our Series D funding round of $3 billion, led by the United Arab Emirates. The financing now values The Boring Company at $23 billion.
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.

Thanks to the @USArmyReserve soldiers from Branch 1 in Nashville for taking the time to tour the Prufrock-MB1 and Prufrock-MB2 tunneling site.
Also loved your appreciation of our “topologically impossible” TBC Mugs!
Friday night tunneling in Nashville!
Prufrock-MB2 is boring through the Music City limestone using 1,000,000+ lb of axial thrust, and 4,000,000+ lb of lateral gripping force.
Part 2 of the 3+ hour Boring Factory tour.
Especially love when John drives a loaded 40,000+ lb Liner Truck with a PS5 controller (1:13:35).
Thanks to @teslaownersSV for spending the day with us!
Prufrock-2 has emerged!
Fun facts:
- 2.28 miles long
- Longest single Vegas Loop tunnel drive (previous TBC record was 2.26)
- 4th tunnel at @WestgateVegas
- ~68k cubic yards of dirt moved
- ~4.8 miles of continuous conveyor belt driven w 6 motors totaling 825 hp
Vegas Loop dropoff at the Airport!
Still in the early phases of the program, providing a small number of rides each day.
The ride includes both a tunnel portion and a long surface portion, with the latter shifting to subsurface when the 2.25 mile Airport Connector twin tunnels open, hopefully in Q1 2026.
Thanks to @LASAirport@LVCVA@ClarkCountyNV@NevadaDBI in reaching this milestone.

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.
