Is Los Angeles' subway system bleeding money, or is Elon Musk just dreaming of a cheaper underground future? The tech mogul has once again set his sights on the City of Angels, this time taking aim at the exorbitant costs associated with its subway projects. Musk, through his company The Boring Company, is touting a vision where digging tunnels could be a bargain compared to the massive price tags of traditional rail expansion.
It all started with a viral post on X, where Musk amplified the idea that his tunneling startup could construct underground passages for a fraction of the cost that L.A. Metro is currently paying for its rail endeavors. He's not just criticizing; he's advocating for tunnels as an underrated solution – one that could be both faster and more economical.
Let's look at the numbers. Los Angeles is on the cusp of completing a nearly 9-mile subway extension (the D Line, or Purple Line) from Koreatown to Westwood. This ambitious project is clocking in at a staggering $9.5 billion, which breaks down to roughly $1 billion per mile for certain sections. And that's not even the most far-reaching plan! The proposed Sepulveda Transit Corridor, an entirely underground route designed to traverse the Santa Monica Mountains, is projected to cost an eye-watering $20 billion to $25 billion for a mere 12 to 14 miles, with service not expected until the late 2030s or early 2040s.
But here's where it gets controversial... Musk's Boring Company has presented plans for highway tunnels in Nashville that are estimated to cost between $240 million and $300 million for a similar length of 10 to 13 miles. This is a tiny fraction of what L.A. is shelling out for its subways. However, it's important to note that these Nashville projects are not yet completed, and the final costs are still up in the air.
And this is the part most people miss... The systems are fundamentally different. The Boring Company's tunnels are designed to be much narrower and are intended for electric vehicles, not high-capacity trains. They feature smaller stations and fewer safety redundancies, which is how they achieve lower costs. The trade-off? A significantly limited passenger capacity compared to heavy rail.
Musk's journey into tunneling began with his frustration over Los Angeles' infamous traffic and what he perceived as glacially slow and incredibly expensive infrastructure development. Early proposals in L.A., including a test tunnel in Hawthorne and a privately funded link to Dodger Stadium, faced significant roadblocks. These included lengthy environmental reviews, permitting challenges, and community opposition. Similar ventures in Chicago and elsewhere were eventually shelved.
The Boring Company's most extensive operational system is currently in Las Vegas. The Las Vegas Convention and Visitors Authority funded an initial underground loop beneath the convention center, which opened in 2021. This system, now known as the Vegas Loop, utilizes Tesla vehicles to transport passengers through short tunnels. It has already served millions of riders, with stations at key locations like the convention center, Resorts World, and Westgate, and ambitious plans for future expansion to the airport, stadium, and downtown areas.
What's a key differentiator for the Vegas Loop's progress? It's largely privately financed. This allows it to bypass many of the federal funding requirements and lengthy approval processes that typically bog down traditional public transit projects, enabling it to move forward at a much faster pace.
So, what do you think? Is Elon Musk onto something with his cost-effective tunneling approach, or are the differences in scale and purpose too significant to draw direct comparisons? Are we paying too much for public transit in cities like Los Angeles? Let us know your thoughts in the comments below!
