VDOT Functional Classification

Virginia updates the road classifications every 10 years and the next update will be published in 2015. The proposed functional classifications are available via an interactive map that can be found here (requires Silverlight). The updates have been conditionally approved and should be used for setting road type in WME.

The previous versions of Functional Highway Maps represent the previous road classifications, and may be used to help understand functional classification changes.

Consult the Road Types (USA) page for further guidance on how to type based on functional class and road signage. Note, however, that where that page says that "signed, numbered state highways" must be designated at least as Minor Highway type, in Virginia that applies only to primary state highways. See Virginia#Road type guidance for more detail.


Functional Highway Maps Classification Suggestions

Rural farm and logging roads that are never open to the public should be marked as Private Road type to prevent routing. Most should be left off the map unless they serve multiple residences or residences out of sight of the main road. The Dirt Road/4x4 Trail designation should be reserved for public (state/locality maintained) dirt roads and Forest Service roads, etc, that a user may actually traverse freely during at least part of the year.

Other Virginia Statewide Resources

  • AARoads Virginia Contains pictures of most BGS on highways as well as other ground level imagery.


Regional Resources

  • Virgina.gov has a comprehensive list of local government GIS activities. The Virginia.gov site includes some of the links below as well as indicating when there is no government GIS site for a county or area.

Resources by City/County

Alleghany County
Arlington County
Botetourt County
City of Alexandria
City of Charlottesville
City of Chesapeake
Chesterfield County
City of Fairfax
  • City of Fairfax GIS Only includes the area within the city limits. See Fairfax County below for the surrounding area.
Fairfax County
Franklin County
Goochland County
Hanover County
City of Harrisonburg
Henrico County
Isle of Wight County
Loudoun County
  • Loudoun County GIS
    • To show street addresses, check "LandRecords"; Address Points, Road Centerline, and Parcel Boundaries underneath LandRecords are useful.
    • To show Census Designated Places, check "Planning" and then underneath check "Census 2010 - CDP"
    • If you are looking to make sure all schools are landmarked in your area, you can find them by checking "Schools" and then "School Sites".
    • "BaseLayers" should be checked by default.
City of Manassas
Page County
Powhatan County
Prince William County
City of Richmond
City of Roanoke
Roanoke County
Rockbridge County
Spotsylvania County
Stafford County
City of Suffolk
  • Suffolk City GIS Includes a "YourMap" tool, which is a bit slow but includes very detailed information. However, recommend considering the OrthoPhotography link first. It's faster, and will still display full parcel data with street names and house numbers. OrthoPhotography will often work fine when YourMap won't even load.
Surry County
City of Virginia Beach
