The Boring Company announced Tuesday that it has selected three American cities — New Orleans, Baltimore, and Dallas — to receive a fully funded, one-mile underground transit loop through its expanded Tunnel Vision Challenge. The announcement came as a surprise: the competition, which launched in January with plans to crown a single winner, ended with the company tripling its commitment after what it described as the "strength and diversity" of the 487 global submissions received.

The three winning projects, which The Boring Company is branding internally as "The Thrilling Three," represent the most aggressive move yet by Elon Musk's tunnel company to export its Las Vegas Loop model beyond Nevada.

A Contest That Outgrew Its Own Ambitions

The Tunnel Vision Challenge launched in January 2026 with a straightforward premise: cities and organizations worldwide could submit proposals for a one-mile underground loop, with The Boring Company pledging to fund and build the winning entry at no cost to the recipient. The goal was to demonstrate that the company's tunneling costs and timelines had reached a level where gifting a loop to a city was feasible as a marketing and proof-of-concept exercise.

By the submission deadline, 487 proposals had arrived from cities and transit authorities across six continents. Company executives said the volume and quality of entries made narrowing to a single winner "an impossible editorial choice," and the decision was made internally to expand the prize pool to three.

"We set out to find one great project and found dozens," the company said in a statement published Tuesday on X. "New Orleans, Baltimore, and Dallas each proposed something we couldn't walk away from."

The Three Winners

The Boring Company did not release the full text of the winning proposals, but provided summary descriptions of the rationale behind each selection.

New Orleans was selected for a proposed loop connecting the French Quarter and the Ernest N. Morial Convention Center — a route that currently requires navigating some of the most congested surface streets in the city during large events. New Orleans has long faced infrastructure constraints from its geography, sitting largely below sea level, which has historically complicated large-scale underground construction. The Boring Company said its small-diameter tunnel approach, which minimizes excavation volume and water table risk, made the New Orleans corridor viable in a way that conventional tunneling would not be.

Baltimore was chosen for a loop proposal connecting the Inner Harbor to key destinations in the city's downtown medical and university corridor. Baltimore has operated without a new major transit infrastructure project for decades, and its selection drew immediate reaction from local officials. Mayor Brandon Scott called the announcement "a once-in-a-generation opportunity for Baltimore's transit future" in a statement published within hours of Tuesday's announcement.

Dallas was selected for a proposal focused on connections within and around the Dallas Convention Center and nearby entertainment district — a use case directly modeled on the LVCC Loop in Las Vegas. Dallas has been one of the fastest-growing major cities in the United States for the past decade and has faced persistent criticism that its transit infrastructure has not kept pace with population growth.

What "Fully Funded" Actually Means

Each winning city will receive a one-mile loop built entirely at The Boring Company's expense, including tunnel boring, vehicle procurement, station construction, and initial operating infrastructure. The company has not specified how long each project will take to complete, nor has it disclosed the estimated construction cost per loop.

For context, the original LVCC Loop — 1.7 miles serving the Las Vegas Convention Center — reportedly cost approximately $52 million to build, a figure The Boring Company and independent analysts have cited as dramatically below conventional subway construction costs, which typically run $500 million to $1 billion per mile in American cities.

Ongoing operations — vehicle maintenance, staffing, and utilities — are not covered under the Tunnel Vision Challenge grant. Each city will be expected to establish an operational structure to run the loop after construction. The Boring Company said it will work with each winner to develop a viable operating model, which in Las Vegas involves the Convention Center authority managing day-to-day operations.

Expanding Beyond Vegas

The three new loops would mark the first time The Boring Company has operated tunnels outside Nevada. The company currently runs the LVCC Loop and the recently opened Resorts World extension in Las Vegas, and has the Downtown Las Vegas Loop under active construction. Proposals in Austin, Chicago, and Los Angeles remain in regulatory or planning phases.

The Tunnel Vision Challenge selections signal a strategic shift toward actively seeding new markets rather than waiting for city governments to initiate and fund transit projects through conventional procurement. By absorbing the capital cost upfront, the company eliminates the political and budgetary friction that has stalled most of its non-Las Vegas proposals for years.

Musk did not post publicly about the announcement on X at the time of publication, which is unusual for a company decision of this scale given his typical social media activity around Boring Company and xAI milestones.
