The Boring Company has completed the first of the two tunnels planned for Las Vegas Convention Center’s underground loop transportation system. The Las Vegas Convention and Visitors Authority (LVCVA) tapped Elon Musk’s company to develop the LVCC loop, which could cost around $52.5 million. The company called this development a “breakthrough” on its Twitter account and retweeted a video of its machinery breaking through a wall in the facility posted by the LVCVA.
