Excavation for the foundations at the Herndon station has begun.

Most of the sound wall at the Innovation Center Station are complete. The foundation for tower crane is within the footprint of the north, track N2 sound wall, not in the N2 track way as noted in my previous post.

The bridge girders over Centerville Road have been set. They are of the same design as the girders over Horsepen Run.

The right of way barrier walls east of Rudder Road have proceeded several hundred feet more further east.

Columns have begun to come out of the ground west of the east abutment west of Rudder Road.

Excavation at the airport station on the mezzanine side of the of the pedestrian tunnel is nearly complete. Columns have begun to come out of the ground west of the station.

All of the mainline columns from the southern most column along Airfright Lane to the shoulder of the Dulles Greenway are done. Girders continue to be set heading north along Autopilot Drive, as of this date 36 have set along Autopilot Drive and 8 along Airfright Lane.

All of the column in the Dulles Yard lead Y are done. I did not go back into the woods to check the progress on rest of the the columns west of the east lead junction, I think we are safe to assume they are mostly done.

No work has begun on the columns in the median of the Dulles Greenway.

Land is being cleared on the north side of the Dulles Greenway to make way for the entrance at the Loudoun Gateway station. Land is also being cleared on the south side for what appears to be a staging area.

Land is being cleared on the remainder of the site at Dulles Yard.

Most of the girders between the abutments over Broad Run have been set. To reduce the disruption to traffic on the Dulles Greenway the contractor built the column in the stream bed and set those girders before building the abutments and setting the on girders either side of the stream.

Test track and Commissioning Facility

The track work on the test track is done. The signals at the crossover are in place south of the E10 Greenbelt interlocking and are covered with bags. The marker coils for the simulated station alone with the signage marking the location of the ends of the station are in place. The simulated station is located under the Greenbelt Road overpass. The north end is roughly 185' north of the north side of the overpass. The center of the platform is located at roughly E 609+95.
