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.

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.

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. @ClarkCountyFD

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.

TBC is excited to announce the first residential Music City Loop station agreement, serving those living at the beautiful Prime, Alcove, and Paramount towers in downtown Nashville. Residents will take an elevator directly to a Loop station within the building, board a Tesla, and be at the airport in ~9 minutes or Lower Broadway in ~2 minutes.

Tunnel Vision Challenge results! We've been overwhelmed with the amazing submissions…so we are announcing three winners! The Thrilling Three are: - NOLA Loop (New Orleans, LA) - Ravens Loop (Baltimore, MD) - University Hills Loop (Dallas, TX) What happens next? TBC and the project stakeholders enter into a rigorous diligence process which includes: - Meetings with elected officials, regulators, community leaders, and business leaders - Geotechnical borings - Utility and subsurface infra investigation Once the diligence (100% funded by TBC) is complete, if all 3 projects are feasible, will fund/build all 3 - this would be awesome. If only 1 is feasible, will fund/build 1. IN ADDITION, there were multiple other projects that TBC thought were so compelling that we are going to continue to work with the entrants and try to get them built. This includes the following two: - Hendersonville Utility Tunnel (Hendersonville, TN) - Morgan's Wonderland Tunnel (San Antonio, TX) Thanks again to all of the participants - your enthusiasm and positivity has been inspiring for the TBC team.
