WMATA: Dulles Corridor Metrorail Project Pictures 10 24 2010,
Tysons 123 (Tysons Center) station


All of the column in the Capitol Beltway VA I-495 Chain Bridge Road VA-123 interchange are complete. Only two pairs columns between the Capitol Beltway interchange and the east end of the Tysons 123 (Tysons Center) station platform remain uncompleted.

All of the columns that will support the Tysons 123 (Tysons Center) station platform east of Tysons Boulevard are done. The columns that will support the Tysons 123 (Tysons Center) station platform west of Tysons Boulevard are in various stages of completion.

The contractor boring the NATM tunnels broke through on the outbound track N2 tunnel in the excavation at the east end of the cut and cover tunnels in the Chain Bridge Road VA-123 Leesburg Pike VA-7 interchange on 10 20 2010. (See Dulles Corridor Metrorail Project progress update e-mail 11 08 2010 for pictures of that) The outbound track N1 tunnel will likely brake through around the end of November.
