Three primary design concepts have emerged regarding this proposed tunnel. The first is the immersed tunnel method where a trench would be dug on the ocean floor, and pre-cast segments would be installed—an endeavor complicated by the uneven topography of the Atlantic seabed.

Alternatively, Musk could draw from advancements demonstrated by The Boring Company in projects such as the Las Vegas Loop, where single-lane tunnels exclusively accommodate Tesla vehicles. This technology utilizes specialized tunnel boring machines designed to handle excavation efficiently.
