The company announced on Twitter this week that Prufrock-1 had reached the Westgate Resort and Prufrock-2 had arrived at the Encore Resort.

From launch to retrieval, Prufrock-2 completed the 716m tunnel in 10 weeks. In comparison, it took more than 10 weeks just to launch Godot, the TBM that built the Las Vegas Convention Centre Loop.

The loops provide passenger transport in Tesla electric cars.

In May, Clark County approved TBC’s plans to extend the Vegas Loop from the Las Vegas Strip corridor. The 40km expansion will include 18 new stations.

The arrival of Prufrock-1 at Westgate and Prufrock-2 at Encore marks significant milestones for the tunneling company’s Vegas Loop project. TBC aims to open the Westgate station of the Vegas Loop by the summer. Vegas Loop station will be connected to the Las Vegas Convention Center via the LVCC Loop. The Westgate station will surface at the Riviera station located at the Las Vegas Convention Center’s West Hall parking lot.

Elon Musk’s tunneling company recently received approval from the Las Vegas planning commission to expand the Vegas Loop’s route.

“It’s gonna change the way that we travel up and down the boulevard and hopefully to the airport and to Allegiant Stadium and everything else. I love that we have the connectivity and downtown and the Medical District and everything,” said Commissioner Trinity Haven Schlottman.
