Workers have completed the second of two underground tunnels for a people mover connecting exhibit halls at an expanded Las Vegas Convention Center.
A spokeswoman says a drilling machine reached the end of the nearly 1-mile (1.6-kilometer) tunnel a little before 1 a.m. Thursday.
The $52.5 million people-mover is being built by billionaire Elon Musk’s company, called The Boring Co.
It's due to open in time for the big CES gadget show in January 2021.
The transit system is key to an ongoing convention center expansion that will add a three-story building across the street from existing exhibit halls.
