Rendering of Dulles Toll Road Land Bridge over Town Center Parkway/Credit: Dulles Corridor Metrorail Project

The flurry of construction you see in the median of the Dulles Toll Road near Reston Parkway isn’t all the Reston Town Center Metro Station.

Designers of the Silver Line’s Phase 2 are planning way ahead — perhaps decades from now — when a possible new road will take vehicle traffic under rather than over the toll road.

Crews have started construction of a so­-called “land bridge structure” in the median. The bridge will enable the future connecter — a four-lane highway linking Town Center Parkway to Sunrise Valley Drive — to be built without disrupting the toll road, said Dulles Corridor Metrorail Project spokeswoman Marcia McAllister.

The structure is being built in the median of the toll road near mile marker 4.8, approximately 500 feet west of the future Reston Town Center Station. That station is slated to open in early 2020.

The bridge was requested by Fairfax County as an element of the Board of Supervisors’ Six Year Transportation Priorities for FY2015 to FY2020. The county pledged $8.7 million for the $157 million underpass project in late 2014.

Building the bridge­-like structure in advance would minimize any impact to Silver Line Phase 2 service during future construction of the planned roadway, McAllister said.

    Way ahead?
    I thought this was a done deal.
    Metro station traffic is a b*tch that is strangling the life out of reston.
    Reston needs more toll road crossings to provide relief to wiehle, reston pkwy, and ffx county pkwy. Why are developer proffers not being asked to fund the costs to defray the substantial impacts the increased traffic will cause?

      It’s a done deal as far as approval but there are no plans to build it anytime soon (and also not the full $157 million). So it will be many years before this happens.

        Ugh. For a planned community there certainly seems to be a lack of infrastructure planning to go along with all the development.

        Seems like the BoS is happy and quick to increase the county tax base, but not spend any of it to augment the infrastructure.

        Thanks Karen.

    My bet is that it will be built sooner than later. Edmund Halley buildings will be torn down, densely redeveloped and the road will be proffered. Perhaps even the Target will go soon. That lot’s got to be a very valuable piece of land by now.

      I am watching for applications to rezone currently residential areas across Sunrise Valley. The Golf Course probe was indicative. But I can see developers buying up whole blocks of houses, say Great Meadow, or Headlands and applying for redevelopment. I know as far east as Oldfield telephone and mail campaigns have offered to buys homes.
