Baltimore-Washington Parkway

The long-term plan is for the Loop to connect Washington DC and New York City. That would involve tunnels under Philadelphia, New Jersey, New York, and part of Delaware. Logically the line would be extended to Richmond, Virginia, Hartford, and New Haven, Connecticut, Providence, Rhode, Island, and Boston.

The Loop Project is a questionable one because Musk’s companies have no Hyperloop vehicles. There is a Hyperloop Test track at SpaceX headquarters in Hawthorne, California that has been used for competitions designed to test Hyperloop vehicles created by teams from universities.
