Elon Musk’s ambitious goal to prevent traffic congestion by building multi-level road and rail networks underneath Los Angeles appears to be gaining support from the right places.

In a tweet, the CEO of Tesla (TSLA) and SpaceX claimed that the revolutionary idea, hatched by his recently founded Boring Company, has already led to “promising conversations” with Los Angeles mayor Eric Garcetti, little over one month after a video illustrating the concept went viral.

Garcetti’s enthusiasm was confirmed in a recent interview on ABC 7’s "Eyewitness Newsmakers." When asked about the city’s transit issues, the mayor responded that Musk’s tunneling idea could represent the best solution to ease Los Angeles's rising traffic problems. During the interview, Garcetti even discussed the idea of creating an express line between LAX airport and L.A.’s Union Station.

“Like many other cities have, I’d love to see maybe even with the new tunneling technology that people like Elon Musk is looking at, whether we could have a quick and direct route from LAX to Union Station,” he said in the interview.

When Musk outlined his plans to build tunnels underneath Los Angeles at a TED conference in Vancouver, the response was mixed. Some in the industry, including Apple (AAPL) co-founder Steve Wozniak, lent support to the idea, claiming that the creation of earthquake-proof underground road and rail networks represented a logical way to deal with growing traffic congestion.

However, the concept was also met with skepticism from some quarters. Critics were particularly vocal about the difficulties that Musk would face in securing permits to burrow holes in the city, as well as potential hurdles sourcing the right technology. Now that the mayor of Los Angeles has seemingly lent his support to the project, some of those issues might eventually become easier to bypass.
