Boring Company Wins Phoenix Airport Loop Contract

LAS VEGAS — The Boring Company has won a contract to build an underground Loop system at Phoenix Sky Harbor International Airport, adding one of the busiest airports in the United States to a pipeline that keeps expanding from its Las Vegas base.

The project calls for a network of tunnels moving passengers between the airport's terminals, its rental-car center, and a nearby transit connection in Tesla vehicles running on demand. For a hub that handles tens of millions of travelers a year, the promise is a fast, weather-proof link that sidesteps surface congestion entirely.

A Proven Playbook Goes National

Phoenix follows a template the company has refined underground in Las Vegas, where the system recently passed 7 million total rides as its station count climbed. The Vegas Loop gave the company years of operating data on throughput, safety, and rider experience — the kind of track record airport authorities want before committing to a new kind of transit.

The airport win also fits a broader pattern of recent contracts. The company's earlier Austin airport Loop deal showed how its pitch resonates with fast-growing cities looking to add capacity without tearing up the surface, and Phoenix extends that momentum to the Southwest's largest aviation hub.

Faster, Cheaper Tunnels

Central to the pitch is the company's tunneling technology, which has steadily driven down the cost and time of boring. Faster machines and a simplified tunnel design let the company quote prices and schedules that traditional rail projects struggle to match, a gap that has become its central selling point to public agencies.

At Phoenix, that efficiency matters. Airport construction is notoriously disruptive, and a system built largely underground promises to add capacity while leaving existing terminals and roadways operating through construction.

Building a Network

Officials framed the deal as a first phase, with room to extend the Loop toward downtown Phoenix and regional destinations if ridership meets expectations. That staged approach mirrors how the Vegas system grew — start with a high-demand core, prove it out, then expand station by station.

For the Boring Company, the Phoenix award is another sign that its model is moving from novelty to infrastructure, winning real contracts at real airports. Project specifics and timelines will be detailed as design work begins, the company said on its official website.

With Las Vegas as a live proof of concept and a widening roster of airport and city deals, the company heads into 2027 with its strongest project pipeline yet — and a growing argument that tunnels, built fast and cheap, can reshape how people move.
