Although not currently proposed, Loop enables future expansion opportunities to communities along the proposed tunnel alignment. Potential future expansions are not currently planned, and would require separate environmental review. Refer to the Potential Expansion Map below for the communities Loop could potentially service indicated by the blue spurs, and are included as a concept, not as a finalized proposal or alignment.

Travel time to spots along the way would vary linearly with distance – in other words, a trip from DC to Greenbelt would take approximately 5 minutes and from Laurel to Baltimore would take approximately 9 minutes. With Loop, all trips are express, independent of the number of stops along the alignment.

Specifics would be developed in cooperation with federal, state, and local agencies and the general public. The Boring Company looks forward to receiving feedback from Washington DC and Maryland residents on potential future station locations.
