Cranes, concrete and structures are slowly emerging from the ground along the Dulles International Airport Access Highway for phase 2 of the Silver Line, which is scheduled to open around 2020.
So far, 26 percent of the $2.7 billion project is complete:
- Design – 94 percent complete
- Construction – 10 percent complete
There’s a massive crane at the site of the future Innovation Center Station.
The crane towers rise about 187 feet with a 252-foot horizontal working arm able to lift 22,000 pounds of steel, concrete, large tools, generators and a wide variety of other materials that will be used to build the stations.
Once the first crane has completed its work at Innovation Center Station it will be disassembled and moved to the Reston Town Center Station site.
Phase 2 of the Silver Line includes:
- 3 stations in Fairfax County
- 1 station at Dulles International Airport
- 2 stations in Loudoun County
Here’s a quick run down of the work happening at each station in Fairfax County and at Dulles airport, according to the Washington Metropolitan Airports Authority, which is constructing the line.
This month, support structures will be installed to help with site excavation and bearing piles. This work will continue into the winter months.
Excavation of the site has begun, and 6,000 cubic yards of dirt of have been removed to make room for the station. The tower crane will help build the station’s foundation. Also, some work is underway at the adjacent Herndon-Monroe Kiss and Ride lot:

To date, 1,902 cubic yards of concrete have been placed for the footings and track wall. Crews will be erecting 170 structural and architectural elements through the winter. Structural steel is scheduled to go up in February.
Excavation of the station is nearly complete, with more than 35,000 cubic yards of soil and rock removed to date. Cast-in-place concrete operations will then begin and continue for approximately nine months. The pedestrian tunnel between Daily Garage 1 and the airport will close in early January while utilities are relocated and the moving walkways are modified to accommodate the tunnel’s tie-in to the future station. During the closure, shuttle bus frequency will increase to transport travelers from the garage to the main terminal. The duration of this closure is not yet known.
The Board of Supervisors received an update at its recent transportation committee meeting:
