In some refreshingly good news, the Las Vegas Convention Center continues to make headway with its expansion, including the underground transportation system from Elon Musk and the Boring Company.

The drilling of a second tunnel, part of the Convention Center Loop, is now underway.

The tunnel system will transport convention attendees from one end of the Convention Center to the other, a distance of 4,486 feet. That’s 0.84962121 miles for the math nerds.

Passengers in the underground transportation system, expected to move up to 4,400 people an hour in Tesla vehicles. The trip will take about a minute, or the average duration of a lovemaking session with this blog. We blame it on the rum.

The $52.5 million underground transportation system is on pace for completion by the end of 2020 but will officially debut in January 2021.

In another notable moment in the convention center expansion, crews just completed a massive concrete pour.

Workers poured 75 million pounds of concrete for a 600,000-square-foot floor and the time lapse video is supremely satisfying. Take a look.

The concrete used in the recent pour required 1,800 trips by concrete trucks, which is the most common means of transporting concrete, other than “in our pants.”

Another fun fact: The convention center’s new exhibit hall will be 328,000-square-feet, and the space will be column-free, making it the largest such space in North America.

Vegas doesn’t do small.

You can keep your eyes on the Las Vegas Convention Center expansion project, as well as Elon Musk’s underground wizardry, on Web cams pointed at the sites.

The LVCVA says the convention center expansion is 77% complete. Oddly specific, but we like it, especially given current events. We’ve had our fill of bad news lately, so it’s great to see a project moving forward, especially one that will result in drawing new business to Las Vegas.

More to come!
