Preliminary Planning for Silver Line Underpass to Begin This Year

Local and state officials plan to explore options to build a Silver Line underpass from Town Center Parkway and Sunset Hills Road to Sunrise Valley Drive.

The project, which is expected to cost around $169 million, is in its early planning phases.

Pending the Fairfax County Board of Supervisors’ approval on Tuesday (May 15), the county’s transportation department and the Virginia Department of Transportation will propose three options for the four-lane underpass.

Preliminary engineering and designing will begin in fiscal year 2020. No timeline for construction has been set.

County officials said the project is a “high priority” to improve circulation in Reston, support traffic from additional development and improve connectivity in the overall road network.

In 2014, the county board approved a plan that recommended constructing the underpass west of Edmund Halley Drive and committed $8.7 million to advance the effort. Three years later, the board incorporated the project in Reston’s funding plan for transportation improvements.

The underpass is planned beneath a future Metrorail line. Metrorail tracks will span the future road roadway extension. 

The board will vote on the agreement between state and county officials to begin exploring options on Tuesday. The scope of the study includes:

  • A review of previous studies
  • Aerial mapping
  • Three planning and profile studies
  • A preliminary project cost estimate
  • Information on environmental impacts

    There must be a Dilbert cartoon somewhere related to the pre-planning…

      Preliminary planning is politician’s talk for “not going to see it for a very long time, if you’re lucky”.

    will the developers pay for it ?
    That’s a joke when the taxpayers have unlimited funds to be tapped

  • Willie Reston

    “No timeline for construction has been set.”

    Why to Sunrise Valley? Why not just to the Metro Station?

      More developers get a free property value increase

      It does?
      Exiting on the south or north side of this proposed road will technically put you next to the parking lot for the station.

      The road between Sunset Hills and Sunrise Valley is sorely needed. If you look at it from an entrance/exit point of view, there is only 1 real entrance to the south side of RTC and that’s through Sunset Hills onto Dominion Parkway.

      On every side of RTC, there are multiple entrances but the south side and that’s where the majority of the traffic gets caught up.

      Sunrise/Sunset onto Reston Parkway.
      Sunrise/Sunset onto Fairfax County Parkway.

      If you work in RTC and live in any area between Reston Parkway and Fairfax County Parkway, you typically add nearly 30 minutes of commute time on what would take only about 3 to 5 minutes to drive.

      Basically, if you live on Glade Dr, you are generally screwed.

      The cut through under the Silver Line is sorely needed for locals.

      Also, if we wanted to look at this as a business perspective, the majority of the office workers on Sunrise Valley don’t actually go to RTC for lunch and things like that.

      Having this cut through should increase business for RTC.

        Meant to say Sunset Hills on to Town Center Parkway.

        Let BP pay for it then

      Because that is where the only parking is located. It may be private buildings now, but powers that be want to change that. Fannie will not be able to build enough parking for what they want to build to house all staff. None of their current locations can handle employees now, that isn’t going to change with the new site. They think everyone will ride metro. They dont now, not even to the Wisconsin building.

    Oh and this is entirely for the community benefit, and not part of the hidden Fannie Mae enticement package? What other tax payer obligations are coming up to get this boondoggle? If they make this “Fannie Only street access” to their new digs there better be a revolt.
