The Washington Post writes that The Boring Company does not list the D.C.-Baltimore tunnel among the potential projects on its site. The project would link the two cities with two tunnels of about 30km in which the cars would move at the speed of 150mph.

Officials say they have not got any indication from TBC that the company would move ahead with the project.
