Roadways and Bridges

Major transportation contains the primary road polygons and bridges in Fairfax County. The original data in this layer was captured during the 1997 data conversion effort for Fairfax County. After that an update capture was completed in 2014 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery. The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos The data in this layer provides the areal extent of the paved and unpaved roads up to the edge of pavement. Major transportation features are features that exist in the rights of way as opposed to roads that are on parcels. This also contains the areas of bridges and medians which exist between divided highways.
