The single-bore tunnel was constructed during 2017‒2018 using a {{convert|4.2|m|adj=on}} diameter tunnel boring machine, giving a finished {{convert|3.8|m|adj=on}} internal diameter. Route{{Boring Test Tunnel}}Most of the route runs outside and set back from the perimeter of Hawthorne Municipal Airport, with a very short section under the corner of the airport fence, without going under the runway.[2] 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 {{convert|530|ft|m|sigfig=4|adj=mid|-radius}} 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.[3] TimelineOn 17 December 2016, Elon Musk stated that he was frustrated with traffic jams, and would start building a tunnel.[4] 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.[5] On 31 January 2018 the Boring Company acquired the land around a family house at 3834 West 119th Place for $500,000.[6] On 9 May 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[7] and Plots 304‒307 behind.[8] On 5 October 2018, the Hawthorne City Council granted an easement for up to {{convert|8600|ft|disp=flip}} of tunnel, in exchange for a structural encroachment fee of $2.5 million. Permission for the first {{convert|700|ft|disp=flip}} of tunnel under SpaceX's own land had been obtained earlier.[9] On 17 October 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.[10] An opening ceremony for the test tunnel was originally scheduled for 10 December 2018,[11] then moved to 18 December 2018.[12] OperationDuring the launch day on 18 December 2018, cars operated using guided busway-style side-facing guide wheels. This fleet of Tesla Model X vehicles travelled at up to {{convert|40|mph|kph|round=5|order=flip}}.
