Excavation is underway on the second of two tunnels that will form a transportation system beneath the Las Vegas Convention Center.
The Convention Center Loop, the first commercial endeavor for Elon Musk's Boring Co., is designed to transport up to 4,400 convention attendees per hour across the convention center's 200-acre campus.
The boring machine tunneled 4,486 feet to complete the first tunnel 40 feet below ground. The second tunnel follows a parallel path alongside the first tunnel, which has been completed.
The $52.5 million system will use Tesla vehicles to whisk convention attendees between three stations in South Hall, Central Hall and new West Hall, scheduled to open in January. The trip from one end of the loop to the other will take about one minute. Convention attendees will be able to ride for free.
Work on the second tunnel is expected to be wrapped up by December, in time for CES.
