The Boring Test Tunnel is a tunnel in Hawthorne, California for testing Hyperloop and Loop-based transportation. It was completed by The Boring Company in late 2018. The single-bore tunnel was constructed during 2017‒2018 using a 4.2-metre (14 ft) diameter tunnel boring machine, giving a finished 3.8-metre (12 ft) internal diameter.
Boring Test Tunnel
The tunnel starts between the Dominguez Channel storm drain and Crenshaw Boulevard at an entrance pit constructed on car park land owned by SpaceX. A short straight section heading northwards is followed by a 530-foot-radius (161.5 m) curve westwards under West 120th Street, then a long straight tunnel, a slight curve and a final short straight to the Exit Shaft. The midpoint of the tunnel is planned to connect with a very short northwards spur to a small car parking system-style car elevator leading up inside a residential garage behind a house at 3834 West 119th Place.
On December 17, 2016, Elon Musk stated that he was frustrated with traffic jams, and would start building a tunnel. By April 2017, The Boring Company had obtained a second-hand tunnel boring machine, transported the machine to Hawthorne, and had it repainted in Boring Company colours.
On January 31, 2018, the Boring Company acquired the land around a family house at 3834 West 119th Place for $500,000. On May 9, 2018, the Boring Company acquired land on the corner of West 120th and Prairie Avenue for $2 million, purchasing the corner plots 309 and 308 at 12007 Prairie Avenue and Plots 304‒307 behind.
On October 5, 2018, the Hawthorne City Council granted an easement for up to 2,600 metres (8,600 ft) of tunnel, in exchange for a structural encroachment fee of $2.5 million. Permission for the first 210 metres (700 ft) of tunnel under SpaceX's own land had been obtained earlier.
On October 17, 2018, in preparation for opening "The Brick Store", the company applied for permission to paint the building at 12003 Prairie Avenue in The Boring Company black-and-white corporate colours.
During the launch day on December 18, 2018, cars operated using guided busway-style side-facing guide wheels. This fleet of Tesla Model X vehicles travelled at up to 65 kilometres per hour (40 mph).
