Work has commenced on the excavation of the tunnels that will hold the conduits that will carry third rail power from the substation to the right of way east of Dulles Airport. Work continues on the installation of the 34.5 KV power feed bus.

Grading work continues from roughly Centreville Road to the location of the east abutment north of Autopilot Drive.

The foundations for the Innovation Center station are mostly done. A tower crane has been erected at what looks like mid platform in the track bed of track N2, north side, of the station.

The east abutment north of Autopilot Drive is well underway.

Excavation for the Dulles Airport station mezzanine has begun. The lanes of Saarinen Circle have been shifted to accommodate the excavation.

There were reports of cracks in the precast girders shortly after they were set on the columns along Air Fright Lane in April. No reports have been made as what will be done with those girders. It seem the cracking issues has been addressed as the Track N2 girders were set on the columns north of the Hertz Rent-a-car entrance on Autopilot Drive.

All but a couple of the mainline columns from southern most column along Airfright Lane to the shoulder of the Dulles Greenway are done. Most of the columns for the east yard lead are done and all of the west yard lead column are done from the junction of the yard leads to the shoulder of the Dulles Greenway. The column for the straddle bents that will support both the mainline and the west yard lead have been built. Work on the column piles in the median of Dulles Greenway has not begun yet.
