In January, the Boring Company, founded by Elon Musk, posted on social media, calling for pitches for 1-mile tunnel ideas. The winner will get their pitched project built for free.

The Boring Company is currently working on a project in Nashville called the Music City Loop. According to the company's website, the project will be a "cutting-edge, zero-emission underground transit system connecting downtown Nashville, Music City Center and Lower Broadway to West End Ave and the Nashville International Airport," and said it will span 13 miles.
