Phase 1 of the Silver Line is 83% finished, and on target for a summer 2013 completion. It will open in late 2013, after a few months of required testing by WMATA. During that time trains will sometimes be visible running on the tracks.

A construction contract will be awarded for Phase 2 in May 2013, with construction starting later that year, and completion anticipated in 2018.

In early November construction crews put in place the pedestrian bridge at Wiehle-Reston East station that crosses over the Dulles access highway. Here’s a photo from the interior:
