隧道的大部分路段均位于霍桑市际机场英语Hawthorne Municipal Airport (California)的机场范围外部,有一个非常短的部分位于机场围栏的角落处,但并非位处跑道上[2]。 隧道起点Dominguez雨水道和克伦肖大道之间的SpaceX停车场下方,穿过120西街,一条大直路和微转弯后抵达终点。隧道的中间处计划连接一个小型汽车升降机[3]

时间线

2016年12月17日, 伊隆·马斯克 表示对塞车感到沮丧,因而着手兴建隧道[4]。2017年4月前,钻洞公司获得一个二手的隧道掘进机,并把机器运送至霍桑,并涂上公司的标志[5]

On 31 January 2018 the Boring Company acquired the land around a family house at 3834 West 119th Place for $0.5 million.[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 2,600米(8,600呎) of tunnel, in exchange for a structural encroachment fee of $2.5 million. Permission for the first 210米(700呎) 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]

隧道原定在2018年12月10日举行开幕仪式[11],其后押后至12月18日[12]

运作

2018年12月18日,钻洞试验隧道正式开始运作,所使用的车辆类似导向巴士。车队中的特斯拉X型车最高时速为65公里。
