We look forward to future conversations with the cities and states along this route and we expect to secure the formal approvals necessary to break ground later this year." Ars also contacted the US Department of Transportation, and a White House spokesperson noted, “We have had promising conversations to date, are committed to transformative infrastructure projects, and believe our greatest solutions have often come from the ingenuity and drive of the private sector.” It’s worth noting that back in January, Musk signalled his willingness to work with President Donald Trump, who made $1 trillion in infrastructure spending through public-private sector partnerships a tenet of his campaign.
Musk became a member of President Trump’s Strategic and Policy Forum, although the Tesla and SpaceX CEO quit his advisory position when Trump announced his intention to withdraw from the Paris Agreement.
In his remarks that day, Musk confirmed the construction was to test out a tunnel-digging project.

At the time, Musk invited investors and press to a party with demo solar roof tiles on homes, but the undertone was that without a deal to buy SolarCity, the solar roof would never happen.
