Breakthrough at Boring Company's LA tunnel

Elon Musk has celebrated the Boring Company breaking through at end of the test tunnel in Los Angeles, US.

The Boring Company tunnel boring machine (TBM) has broken through to the vertical shaft in Hawthorne, Los Angeles, Elon Musk has tweeted.

“Congratulations @BoringCompany on completing the LA/Hawthorne tunnel! Cutting edge technology!” Musk wrote in the tweet, which included footage of the TBM (see below). 

The 4.3km test tunnel will be used for Boring Company engineers as a “proof-of-process” tunnel, to develop construction techniques, and system and safety testing of the transportation. It would run within the City of Los Angeles and Culver City.

In July, the firm said the entrance to the 3.65m diameter tunnel is on private land and bored between 9.4m to 21m below ground. There will be no stations and, according the Boring Company, the tunnel would take around nine months to complete.

The Los Angeles City Council’s public works committee unanimously approved an environmental review exemption for the test tunnel (shown in red on the map below). The exemption allows developments to not undertake an environmental impact report if they can be built on less 2ha of land and use existing public services.
