Silver Line Phase 2 Slowly Emerging from the Ground

Construction at Dulles Airport Metro Station

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


Cranes, Oh My!

craneOne of the most visible signs of construction and progress is kind of hard to miss.

There’s a massive crane at the site of the future Innovation Center Station.

And another crane is coming this week to the future Herndon 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.

What’s Happening at the Stations

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.


>>Reston Town Center Station

This month, support structures will be installed to help with site excavation and bearing piles. This work will continue into the winter months.


>>Herndon Station

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:


>>Innovation Center Station

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.


>>Dulles Airport Station

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.
