Tesla's FSD Starts Being Used in Underground Las Vegas Airport Loop, Roadmap Outlined

Last week, The Boring Company (TBC) published a detailed roadmap for building a direct underground link between the Las Vegas Strip and Harry Reid International Airport.

According to TBC President Steve Davis, the company has already started limited airport pickups, initiating a four-phase rollout intended to reduce surface-level traffic.

Four-Phase Roadmap

The airport connection will be activated in stages so passengers can begin traveling point to point immediately rather than waiting for a single, final build-out.

Phase 1

Phase 1 is currently active and provides limited test rides—about 50 per day—using existing Loop stations at Resorts World, Encore, Westgate, and the Las Vegas Convention Center. This week, 100 of the fleet’s 130 Teslas were fitted with the necessary airport transponders, enabling pickups and operation on a hybrid route that combines tunnel travel with surface streets.

Phase 2

Phase 2, planned to begin in the coming months, will add a new 2.2-mile, dual-direction tunnel now under construction. That section will run from Westgate toward Paradise Road; once operational, vehicles will exit the tunnel much closer to the airport, removing roughly two miles of surface traffic from the trip.

Phase 3

Phase 3 will extend the tunnel network nearer to Terminal 1 at Harry Reid, bypassing a major congestion point at Tropicana and University Center. To handle the increased volume, Phase 3 will also expand the Loop fleet to nearly 300 vehicles.

Phase 4

The final phase calls for a dedicated underground station directly at the airport terminals, allowing passengers to step from a plane into a Tesla without going aboveground.

FSD Goes Underground

As the network expands, the vehicles operating inside the tunnels are receiving software and marking updates.

TBC vehicles have recently been seen bearing new Tesla Self-Driving decals and are using FSD (Supervised) for the first time to begin traversing the Loop. The cars remain monitored by TBC employees and are not fully autonomous.

The Loop now serves as a validation track for Tesla’s FSD, focusing on close-range driving in the tight confines of the Boring Loop. In certain straightaway sections, the controlled environment will eventually support speeds up to 150 mph.

2027 Target

TBC aims to complete the full 68-mile Vegas Loop by 2027, but needs to accelerate approvals as well as construction.

The company requires more than 600 additional permits across Clark County to finish the system. At the current rate of about one approval every one to two weeks, completion would take decades; TBC is coordinating with local officials to pursue an operator-style permitting process similar to how SpaceX handles approvals at Starbase.
